1. Introduction

F000539F000451F000648

This manual includes information for the normaloperation, maintenance, and servicing of the Series90 family of hydrostatic pumps and motors. Themanual includes the description of the units and theirindividual components, troubleshooting information,adjustment instructions, and minor repair procedures.Unit warranty obligations should not be affected ifmaintenance, adjustment, and minor repairs are per-formed according to the procedures described in thismanual.

Many service and adjustment activities can be per-formed without removing the unit from the vehicle ormachine. However, adequate access to the unit must

be available, and the unit must be thoroughly cleanedbefore beginning maintenance, adjustment, or repairactivities. Since dirt and contamination are the great-est enemies of any type of hydraulic equipment,cleanliness requirements must be strictly adhered to.This is especially important when changing the sys-tem filter and during adjustment and repair activities.

A worldwide network of Sauer-Sundstrand Autho-rized Service Centers is available should repairs beneeded. Contact any Sauer-Sundstrand AuthorizedService Center for details. A list of all Service Centerscan be found in bulletin BLN-2-40527, or in brochureSAW (Ident. No. 698266).

1.1 Use of This Manual

Loss of Hydrostatic Braking Ability

WARNINGWhen Series 90 units are used in vehicularhydrostatic drive systems, the loss of hydro-static drive line power in any mode of opera-tion (e.g. acceleration, deceleration or “neu-tral” mode) may cause a loss of hydrostaticbraking capacity. A braking system which isindependent of the hydrostatic transmissionmust, therefore, be provided which is adequateto stop and hold the system should the con-dition develop.

Disable Work Function

WARNINGCertain service procedures may require thevehicle/machine to be disabled (wheels raisedoff the ground, work function disconnected,etc.) while performing them in order to preventinjury to the technician and bystanders.

Fluid Under High Pressure

WARNINGUse caution when dealing with hydraulic fluidunder pressure. Escaping hydraulic fluid un-der pressure can have sufficient force to pen-etrate your skin causing serious injury. Thisfluid may also be hot enough to burn. Seriousinfection or reactions can develop if propermedical treatment is not administered immedi-ately.

Flammable Cleaning Solvents

WARNINGSome cleaning solvents are flammable. Toavoid possible fire, do not use cleaning sol-vents in an area where a source of ignition maybe present.

1.2 Safety Precautions

Observe the following safety precautions when using and servicing hydrostatic products.

2.1.1 Variable Displacement Pumps

The Variable Displacement Pump (PV) is designed toconvert an input torque into hydraulic power. Theinput shaft turns the pump cylinder which contains aring of pistons. The pistons run against a tilted plate,called the swashplate. This causes the pistons tocompress the hydraulic fluid which imparts the inputenergy into the hydraulic fluid. The high pressure fluidis then ported out to provide power to a remotefunction.

The swashplate angle can be varied by the controlpiston. Altering the swashplate angle varies the dis-placement of fluid in a given revolution of the inputshaft. A larger angle causes greater displacementwhich yields greater output torque for a given input. Asmaller angle reduces the displacement per revolu-tion and yields greater speed for a given input.

2.1.2 Fixed Displacement Motor

The Fixed Displacement Motor (MF) is designed toconvert an input of hydraulic power into an outputtorque. It operates in the reverse manner of thepump. The high pressure hydraulic fluid enters throughthe input port. The fluid pressure builds behind thepistons causing them to move down the swashplate(the path of least resistance). As the piston returns upthe swashplate again, the fluid is allowed to exitthrough the exit port. The spinning pistons are housedin a cylinder which is connected to the output shaft.The output torque can be applied to a mechanicalfunction.

The Basic Closed Circuit

The main ports of the pump are connected by hydrau-lic lines to the main ports of the motor. Fluid flows, ineither direction, from the pump to the motor then backto the pump in this closed circuit. Either of the hydrau-lic lines can be under high pressure. The position ofthe pump swashplate determines which line is highpressure as well as the direction of fluid flow.

Case Drain and Heat Exchanger

The pump and motor require case drain lines toremove hot fluid from the system. The motor shouldbe drained from its topmost drain port to ensure thecase remains full of fluid. The motor case drain canthen be connected to the lower drain port on the pumphousing and out the top most port. A heat exchanger,with a bypass valve, is required to cool the case drainfluid before it returns to the reservoir.

2.3 Common Features of Pumps and Motors

2.3.1 End Caps and Shafts

Series 90 pumps and motors can be supplied with avariety of end caps and shafts to allow for almost anyconfiguration. For pumps, end caps are availablewith system ports on either side ("side ports") or bothports on one side ("twin ports"). Motors have endcaps with ports on the face of the end cap ("axialports") or both ports on one side ("twin ports"). Seethe Series 90 Technical Information manuals (BLN-10029 and BLN-10030) or the Series 90 Price Book(BLN-2-40588) for information on available options.Removing the end cap will void the warranty on aSeries 90 pump or motor.

2.3.2 Speed Sensors

An optional speed sensor can be installed on Series90 pumps and motors to provide unit speed informa-tion. The sensor reads a magnetic ring wrappedabout the unit's cylinder. See Sec. 4 to locate thespeed sensor port. See Sec. 8.4 and 9.6 to adjust andinstall the sensor.

2.4.1 Charge Pump

The charge pump is necessary to supply cool fluid tothe system, to maintain positive pressure in the mainsystem loop, to provide pressure to operate thecontrol system, and to make up for internal leakage.Charge pressure must be at its specified pressureunder all conditions of driving and braking to preventdamage to the transmission.

The charge pump is a fixed-displacement, gerotortype pump installed in the variable displacementpump and driven off the main pump shaft. Chargepressure is limited by a relief valve

The standard charge pump will bemost applications. However, if the chavailable for the given main pump equate, a gear pump may be mountemounting pad (Sec. 2.4.8) and supadditional charge flow. For repairpump see Sec. 9.2.4.

2.4.4 Multi-Function Valves

All Series 90 pumps include two multi-function valves.The multi-function valve incorporates the systemcheck valve, the pressure limiter valve, the highpressure relief valve, and the bypass valve in areplaceable cartridge. These functions are describedseparately. There are two multi-function valve car-tridges in each Series 90 pump to handle functions ineither direction. See Secs. 8.1.2 and 9.2.1 for adjust-ments and repairs.

NOTE: Some multi-function valves do not in-clude a pressure limiter valve.

2.4.5 Pressure Limiter and High PressureRelief Valves

Series 90 pumps are designed with a sequencedpressure limiting system and high pressure reliefvalves. When the preset pressure is reached, thepressure limiter system acts to rapidly destroke thepump so as to limit the system pressure. For unusu-ally rapid load application, the high pressure reliefvalve acts to immediately limit system pressure bycross-porting system flow to the low pressure side ofthe loop. The pressure limiter valve acts as the pilotfor the high pressure relief valve spool. The highpressure relief valve is sequenced to operate atapproximately 35 bar (500 psi) above the level thatinitiates the pressure limiter valve.

Both the pressure limiter sensing valves and reliefvalves are built into the multi-function valves (seeabove).

NOTE: For some applications, such as dual pathvehicles, the pressure limiter function may bedefeated so that only the high pressure reliefvalve function remains.

2.4.6 Bypass Valves

The bypass valves ("tow") can be operated when it isdesired to move the vehicle or mechanical functionwhen the pump is not running. The valve is opened bymanually resetting the valve position (Sec. 8.1.3).

The bypass valves are built into the multi-functionvalves (see above).

2.4.7 Displacement Limiters

Series 90 pumps sizes 042 - 250 are designed foroptional mechanical displacement (stroke) limiters.The maximum displacement of the pump can belimited in either direction.

The setting can be set as low as 0° in either direction.

For instructions on adjustment see Sec. 8.1.5.

2.4.8 Auxiliary Mounting Pads

Auxiliary mounting pads are available on all Series 90pumps. SAE A through E and H mounts are available(availability varies by pump size). This pad is used formounting auxiliary hydraulic pumps and for mountingadditional Series 90 pumps to make tandem pumps.The pads allow for full through-torque capability.

2.4.9 Filtration Options

All Series 90 pumps are available with provisions foreither suction or charge pressure filtration (integral orremote mounted) to filter the fluid entering the chargecircuit. (See Sec. 6 for more information.)

Suction Filtration

The suction filter is placed in the circuit between thereservoir and the inlet to the charge pump. Whensuction filtration is used, a reducer fitting is placed inthe charge pressure gauge port (M3). Filtration de-vices of this type are provided by the user.

Charge Pressure Filtration

The pressure filter may be integrally mounted directlyon the pump or a filter may be remotely mounted forease of servicing.

A 200 mesh screen, located in the reservoir or thecharge inlet line, is recommended when using thisfiltration option. A non-bypass filter is preferred on alltypes of filtration.

2.4.10 Pressure Override (POR) - 180Frame Size Only

The pressure override valve (POR) modulates thecontrol pressure to the displacement control to main-tain a pump displacement which will produce a sys-tem pressure level less than or equal to the PORsetting. For unusually rapid load application, the highpressure relief valve function of the multifunctionvalves is available to also limit the pressure level.

The pressure override consists of a three-way nor-mally open valve which operates in series with thepump displacement control. Control supply pressureis normally ported through the pressure overridevalve to the displacement control valve for controllingthe pump's displacement. If the system demands apressure above the override setting, the POR valvewill override the control by reducing the control pres-sure supplied to the displacement control. As thecontrol pressure reduces, the internal forces tendingto rotate the swashplate overcome the force of theservo pistons and allow the pump's displacement todecrease.

2.5 Pump Control Options

2.5.1 Manual Displacement Control (MDC)

The manual displacement control converts a mechani-cal input signal to a hydraulic signal using a spring-centered four-way servo valve. This valve portshydraulic pressure to either side of a dual-actingservo piston. The servo piston rotates the cradleswashplate through an angular rotation of ±17°, thusvarying the pump’s displacement from full displace-ment in one direction to full displacement in theopposite direction. The MDC is designed so theangular position of the pump swashplate is propor-tional to the rotation of the control input shaft. Foradjustments see 8.2.1; for repairs see 9.3.2, 9.3.8.

Non-Linear MDC

The non-linear manual displacement control (photoin Sec. 8.2.2) operates in the same manner as theregular MDC except that it is designed so the changein the angular position of the pump swashplate pro-gressively increases as the control input shaft isrotated toward its maximum displacement position.For adjustments see Sec. 8.2.2; for repairs see 9.3.2.

Solenoid Override Valve

A solenoid override valve option (not shown here) isavailable for MDC. This safety feature will return theswashplate to zero displacement position when acti-vated. The valve may be set in either a normally openor normally closed mode. For repairs see 9.3.3, 9.3.4.

Neutral Start Switch (NSS)

The neutral start switch is an optional feature avail-able with MDC. When connected properly with thevehicle’s electrical system, the neutral start switchensures that the prime mover can be started onlywhen the control is in a neutral position. For adjust-ments see Sec. 8.2.3.

2.5.2 Hydraulic Displacement Control (HDC)

The hydraulic displacement control uses a hydraulicinput signal to operate a spring-centered four-wayservo valve. This valve ports hydraulic pressure toeither side of a dual-acting servo piston. The servopiston rotates the cradle swashplate through anangular rotation of ±17°, thus varying the pump’sdisplacement from full displacement in one directionto full displacement in the opposite direction. TheHDC is designed so the angular position of the pumpswashplate is proportional to input pressure. Foradjustments see 8.2.4; for repairs see 9.3.5, 9.3.8.

2.5.3 Electric Displacement Control (EDC)

The electric displacement control is similar to thehydraulic displacement control with the input signalpressure controlled by a pressure control pilot (PCP)valve. The PCP valve converts a DC electrical inputsignal to a hydraulic signal which operates a spring-centered four-way servo valve. This valve ports hy-draulic pressure to either side of a dual-acting servopiston. The servo piston rotates the cradle swash-plate through an angular rotation of ±17°, thus vary-ing the pump’s displacement from full displacementin one direction to full displacement in the oppositedirection. The control is designed so the angularposition of the swashplate is proportional to the EDCinput. For neutral adjustment see Sec. 8.2.4; forrepairs see Sec. 9.3.5, 9.3.6, and 9.3.8.

2.5.4 Automotive Control (AC and AC II)

Automotive Control (AC) allows a vehicle to be drivenin a manner similar to an automobile with an auto-matic transmission.

The AC control includes a three-position electriccontrol to provide direction control.

The AC II control can be combined with a manual,hydraulic, or electric displacement control to provideboth direction control and control over maximumvehicle speed. It may also be combined with a 3-position electric control to provide direction control.

2.5.5 3-Position (FNR) Electric Control

This control utilizes a 12 or 24 VDC electricallyoperated spool valve to port pressure to either side ofthe pump displacement control piston. Energizingone of the solenoids will cause the pump to go to itsmaximum displacement in the corresponding direc-tion.

All functions of the three-position (FNR) electric con-trol are preset at the factory. For repairs, see Sec.9.3.7.

2.6 Motor Features

2.6.1 Motor Loop Flushing Valve andCharge Relief Valve

All Series 90 motors are designed to accommodate aloop flushing valve. The loop flushing valve is used ininstallations which require additional fluid to be re-moved from the main hydraulic circuit because oftransmission cooling requirements, or unusual cir-cuits requiring additional loop flushing to removeexcessive contamination in the high pressure circuit.

A shuttle valve and charge relief valve are installed inthe motor end cap to provide the loop flushing func-tion. The shuttle valve provides a circuit between thelow pressure side of the closed loop and the chargerelief valve in the motor end cap.

The motor charge relief valve regulates the chargepressure level only when there is a pressure differen-tial in the main loop. The shuttle valve is springcentered to the closed position so that no high pres-sure fluid is lost from the circuit when reversingpressures.

For charge relief valve adjustment see Sec. 8.3.1, forrepairs see Sec. 9.4.1.

Series 90 Start-Up 5

The following start-up procedure should always befollowed when starting-up a new Series 90 installa-tion or when restarting an installation in which eitherthe pump or motor had been removed.

WARNINGThe following procedure may require the ve-hicle/machine to be disabled (wheels raised offthe ground, work function disconnected, etc.)while performing the procedure in order toprevent injury to the technician and bystanders.Take necessary safety precautions beforemoving the vehicle/machine.

Prior to installing the pump and/or motor, inspect theunits for damage incurred during shipping and han-dling. Make certain all system components (reser-voir, hoses, valves, fittings, heat exchanger, etc.) areclean prior to filling with fluid.

Fill the reservoir with recommended hydraulic fluid.This fluid should be passed through a 10 micron(nominal, no bypass) filter prior to entering the reser-voir. The use of contaminated fluid will cause damageto the components, which may result in unexpectedvehicle/machine movement. See the publicationsBLN-9887 and SDF 697581 for further related infor-mation.

The inlet line leading from the reservoir to the pumpmust be filled prior to start-up. Check inlet line forproperly tightened fittings and make sure it is free ofrestrictions and air leaks.

Be certain to fill the pump and/or motor housingwith clean hydraulic fluid prior to start up. Fill thehousing by pouring filtered oil into the upper casedrain port.

Install a 50 bar (or 1000 psi) pressure gauge in thecharge pressure gauge port (see Sec. 4.2 for loca-tion) to monitor the charge pressure during start-up.

It is recommended that the external control inputsignal (linkage for MDC, hydraulic lines for HDC, or

electrical connections for EDC) be disconnected atthe pump control until after initial start-up. This willensure that the pump remains in its neutral position.

WARNINGDo not start prime mover unless pump is inneutral position ( 0° swashplate angle). Takeprecautions to prevent machine movement incase pump is actuated during initial start up.

“Jog” or slowly rotate prime mover until charge pres-sure starts to rise. Start the prime mover and run atthe lowest possible RPM until charge pressure hasbeen established. Excess air may be bled from thehigh pressure lines through the high pressure systemgauge port.

Once charge pressure has been established, in-crease speed to normal operating RPM. Chargepressure should be as indicated in the pump modelcode (see Sec. 8.1.1). If charge pressure is inad-equate, shut down and determine cause for improperpressure. Refer to Troubleshooting Sec. 7.

WARNINGInadequate charge pressure will affect theoperator’s ability to control the machine.

Shut down the prime mover and connect the externalcontrol input signal. Also reconnect the machinefunction if disconnected earlier. Start the prime mover,checking to be certain the pump remains in neutral.With the prime mover at normal operating speed,slowly check for forward and reverse machine opera-tion.

Charge pressure may slightly decrease during for-ward or reverse operation. Continue to cycle slowlybetween forward and reverse for at least five minutes.

Shut down prime mover, remove gauges, and plugports. Check reservoir level and add filtered fluid ifneeded.

The transmission is now ready for operation.

Series 90 Fluid and Filter Maintenance 6

To ensure optimum service life of Series 90 products,regular maintenance of the fluid and filter must beperformed. Contaminated fluid is the main cause ofunit failure. Care should be taken to maintain fluidcleanliness while performing any service procedure.

Check the reservoir daily for proper fluid level, thepresence of water (noted by a cloudy to milky appear-ance, or free water in bottom of reservoir), and rancidfluid odor (indicating excessive heat). If either ofthese conditions occur, change the fluid and filterimmediately.

It is recommended that the fluid and filter bechanged per the vehicle/machine manufacturer’srecommendations or at the following intervals:

It may be necessary to change the fluid more fre-quently than the above intervals if the fluid becomescontaminated with foreign matter (dirt, water, grease,etc.) or if the fluid has been subjected to temperaturelevels greater than the recommended maximum.Never reuse fluid.

The filter should be changed whenever the fluid ischanged or whenever the filter indicator shows that itis necessary to change the filter.

Filters can be in either pressure filtration or suctionfiltration configurations. For suction filtration, filtersshould have a Beta-ratio of β

10>2. For charge pres-

sure filtration, filters should have a Beta-ratio ofβ

10>10. See Sauer-Sundstrand publication BLN-9887

or 697581 and ATI-E 9201 for more information onfiltration.

8. Inspections an d Adjustments

This section offers instruction on how to perform inspections and adjustments on pump and motor components.Read through the entire related section before beginning a service activity. Refer to Sec. 4 for location of gaugeports and suggested gauge size.

8.1 Pump Adjustments

8.1.1 Charge Relief Valve Adjustment

The following procedure explains how to check andadjust the charge relief valve. (For description seeSec. 2.4.2.)

WARNINGThe following procedure may require the ve-hicle/machine to be disabled (wheels raised offthe ground, work function disconnected, etc.)in order to prevent injury to the technician andbystanders.

1. To measure pump charge pressure, install a pres-sure gauge in the pump charge pressure gaugeport (M3). Also install a gauge to measure casepressure (tee into L1 or L2 or use servo gaugeport). Operate the system with the pump in “neu-tral” (zero displacement) when measuring pumpcharge pressure.

2. The table on the following page shows the accept-able pump charge pressure range for some nomi-nal charge relief valve settings (see sample modelcode at right). These pressures assume 1775pump rpm and a reservoir temperature of 49°C(120°F ), and are referenced to case pressure(see footnote on next page). Smaller displace-ment charge pumps will produce charge pressurereadings in the lower portion of the range, whilelarger displacement charge pumps will producereadings in the higher portion of the range.

NOTE: These pressures assume a pump speedof 1775 rpm. At higher pump input speeds (withhigher charge flows) the charge pressure will riseover the rated setting.

3. Earlier production Series 90 pumps are equippedwith a shim adjustable charge relief valve. Shimkits are available from Sauer-Sundstrand. Adjust-ment of charge pressure is accomplished by re-moving the plug [1 inch Hex] and changing theshim thickness behind the spring. The plug for thistype of charge relief valve should be torqued to 68Nm (50 lbf•ft).

Later production Series 90 pumps are equippedwith an external screw adjustable charge reliefvalve. Adjustment of the charge pressure is ac-complished by loosening the lock nut (with a 1-1/16 inch hex wrench for 030 through 100 units, ora 1-5/8 inch hex wrench for 130 through 250units), and turning the adjustment plug with alarge screwdriver or a 1/2 inch hex wrench. Clock-wise rotation of the plug increases the setting, andcounterclockwise rotation decreases the setting(at a rate of approximately 3.4 bar (50 psi) perturn). The lock nut for this type of charge reliefvalve should be torqued to 52 Nm (38 lbf•ft).

4. Once the desired charge pressure setting isachieved, remove the gauges.

8.1.2 Multi-Function Valve PressureAdjustment

Adjustment of the pressure limiter setting and thehigh pressure relief valve setting is accomplishedsimultaneously. The latter is automatically set ap-proximately 35 bar (500 psi) above the former. Fordescription of multi-function valve see Sec. 2.4.4.

In order to adjust the pressure limiter setting, themotor output shaft must be locked so it does notrotate. This may be accomplished by locking thevehicle’s brakes or rigidly fixing the work function soit cannot rotate.

WARNINGTake necessary precautions that the motorshaft remains stationary during the adjust-ment procedure.

1. Install two 1000 bar (or 10,000 psi) pressuregauges in the high pressure gauge ports (M1 andM2). Install a 50 bar (or 1000 psi) pressure gaugein the pump charge pressure gauge port (M3).

2. Start the prime mover and operate at normalspeed.

3. Loosen locking nut (smallest hex on multi-func-tion valve) with a 10 mm wrench for earlier 042through 100 frame size units, a 19 mm wrench for030 and later 042 through 100 frame size units, ora 13 mm wrench for earlier 130 frame size units.

4. Insert a 3 mm (early 042 through 100 units), 5 mm030 and (late 042 through 100 units), or 4 mm(earlier 130 units) internal hex wrench into thepressure adjusting screw.

NOTE: A plastic dust plug is installed in theadjusting screw on 030 and late 042 through 250units.

5. The factory preset pressure limiter setting is shownon the model code as at right. It is referenced tocharge pressure, so the pressure limiter setting isthe difference between the high and low pressuresides of the system loop. Activate or move thecontrol input so that pressure increases in the highpressure side of the closed circuit to the pressurelimiter pressure setting. The pressure limiter set-ting is reached when the pressure stops increas-ing and remains steady at a given pressure level(as shown on the gauges).

6. Return the pump to its “neutral” (zero flow) posi-tion and adjust the pressure limiter setting byrotating the pressure adjusting screw with theinternal hex wrench.

Clockwise rotation of the pressure adjustmentscrew will increase the pressure setting, andcounterclockwise rotation will decrease the pres-sure setting. Each complete rotation of the pres-sure adjusting screw changes the pressure set-ting by approximately 83 bar (1200 psi) on earlier042 through 100 units, or by approximately 93 bar(1350 psi) on 030 and later 042 through 100 units.

7. To verify the actual pressure setting, actuate ormove the control input so that the pump againdevelops pressure in the high pressure circuit tothe newly adjusted pressure limiter pressure set-ting, and read the high pressure gauge. Thenallow the pump to return to its “neutral” position.The pressure in the high pressure circuit shouldreturn to the charge pressure setting.

8. While holding the pressure adjusting screw sta-tionary, tighten the pressure adjusting screw locknut to 3 Nm (26 in•lbf) on early production units, or16 Nm (12 ft•lbf) on late production units. Do notover-torque.

9. Shut down the prime mover, remove the gaugesand install the gauge port plugs. Replace theplastic dust plugs (if used).

The same procedure is used for setting the pressurelimit of the other multi-function valve, but the controlinput signal must be activated or moved in the oppo-site direction so that high pressure develops in theopposite side of the closed circuit.

Loosening and Rotating Bypass Hex on Multi-Function Valve

8.1.3 Engaging the Bypass Function

The bypass function (see Sec. 2.4.6 for description)is performed by the multi-function valve cartridges.The prime mover should be shut down when openingor closing the bypass valves.

The bypass valves on both of the multi-functionvalves must be opened to engaged the bypass func-tion.

1. Using a 1-1/16 inch (030 through 100) or 1-3/8inch (130 through 250) wrench on the middlesized hex of the multi-function valve cartridge, anda 1-1/4 inch (030 through 100) or 1-5/8 inch (130through 250) wrench on the large hex to preventrotation of the cartridge assembly, rotate the middlehex three revolutions counterclockwise to openthe bypass valve. Do not rotate more than 3-1/2revolutions, as additional rotation will permit ex-ternal leakage.

2. For units with an MDC-type control, prior to mov-ing the vehicle or otherwise causing the motorshaft to turn, move the control handle of themanual displacement control on the pump to themaximum full forward position. Hold the handle inthis position during bypass valve operation.

WARNING“Tow” at extremely low speeds and for shortdistances only.

3. To close the bypass valve, rotate the middle hexclockwise until it is seated. Then torque the middlehex to 41 Nm (30 lbf•ft).

1. Install two 1000 bar (or 10,000 psi) pressuregauges in the high pressure gauge ports (M1 andM2). Install a 50 bar (or 1000 psi) pressure gaugein the pump charge pressure gauge port (M3).

2. Start the prime mover and operate at normalspeed.

3. With the pump operating at approximately 20%displacement, load the work function and note thepressure as the POR valve operates (pump dis-placement reduces to “zero”).

4. Adjustment of the pressure override setting ismade by loosening the lock nut with a 9/16 inchhex wrench and turning the adjustment screw witha 3/16 inch internal hex wrench. The POR settingshould be at least 50 bar (750 psi) below the highpressure relief valve setting of the multi-functionvalves for proper operation.

5. Following the adjustment, torque the lock nut to 43Nm (32 lbf•ft).

6. Shut down the prime mover and remove thegauges and install the gauge port plugs.

Loosen Displacement Limiter Lock Nut

8.1.5 Displacement Limiter Adjustment

The maximum displacement can be limited in eitherdirection (see Sec. 2.4.7).

1. Loosen the seal lock nut retaining the displace-ment limiter adjusting screw.

2. Rotate the adjusting screw.

Rotating the adjusting screw clockwise will de-crease the maximum displacement of the pumpwhile rotating the adjusting screw counterclockwisewill increase the maximum displacement.

WARNINGSCare should be taken in adjusting displace-ment limiters to avoid undesirable flow or speedconditions. See Sec. 3 for speed and pressurelimits.

The seal lock nut must be retorqued after everyadjustment to prevent an unexpected changein operating conditions and to prevent externalleakage during unit operation.

3. After establishing the desired maximum displace-ment setting, tighten the lock nut on the adjustingscrew as follows.

8.2 Pump Contro l Adjustments

8.2.1 Standard Manual DisplacementControl (MDC) Adjustment

There are no adjustable elements in the manualdisplacement control. The control spool is held in its“neutral” position by centering springs and washerson each end of the spool. Since there is no centeringspring on the control input shaft, the shaft will auto-matically assume the appropriate position when thecontrol is installed on the pump.

For a functional description see Sec. 2.5.1.

This adjustment must be made on a test stand or onthe vehicle/machine with the prime mover operating.

WARNINGThe following procedure requires the vehicle/machine to be disabled (wheels raised off theground, work function disconnected, etc.) inorder to prevent injury to the technician andbystanders.

1. Install two 50 bar (or 1000 psi) gauges in each ofthe displacement control cylinder gauge ports(M4 and M5). Disconnect the external controllinkage from the control handle and make certainthe control shaft is in its “neutral” position. Start theprime mover and operate at normal speed.

2. Loosen the lock nut on the neutral adjusting screwwith a 13 mm hex wrench.

3. Using a 4 mm internal hex wrench, rotate theneutral adjusting screw clockwise until the pres-sure increases on one of the pressure gauges.Note the angular position of the wrench.

4. Rotate the adjusting screw counterclockwise untilthe pressure increases by an equal amount on theother gauge. Note the angular position of thewrench.

5. Rotate the adjusting screw clockwise half thedistance between the locations noted above. Thegauges should read the same pressure (casepressure), indicating that the control is in its “neu-tral” position.

6. Hold the adjusting screw stationary and tightenthe lock nut to 13.6 Nm (10 in•lbf). Do notovertorque the nut.

7. Once the neutral position is set, stop the primemover, remove the gauges, and install the gaugeport plugs. Reconnect the external control link-age.

8.2.3 MDC Neutral Start Switch (NSS)Adjustments

The neutral start switch (NSS) provides a means toprevent the system prime mover from starting whilethe pump control handle and control input shaft are ina position which would command the pump to go “in-stroke” in either the “forward” or “reverse” direction.

When the control input shaft is in its “neutral” position,the inner end of the switch pin moves into a slot on theeccentric cam attached to the control shaft. Thisallows the spring loaded NSS to close, completingthe electrical starting circuit for the prime mover.

When the control input shaft is NOT in its “neutral”position, the eccentric cam moves the switch pin outof the slot. This forces the NSS to open, breaking theelectrical starting circuit for the prime mover.

The NSS must be adjusted to meet the followingthree requirements:

i. The distance the control handle can be turnedwithout opening the NSS is called the “NSSdeadband.” The distance the control handle canbe moved without moving the control spool enoughto port hydraulic fluid to the pump displacementcontrol cylinders is called the “control deadband.”These deadbands must be centered in relation toeach other.

Since the position of the control deadband cannotbe adjusted, the position of the NSS deadbandmust be adjusted to match it. The switch pin islocated in an eccentric plug which is turned tomove the center of the NSS deadband.

ii. The NSS deadband must be wide enough so theNSS will not open within the loose area of controlhandle movement caused by normal operatingclearances in the control linkage (control shaft“free-play”). By setting the NSS to open outsidethis area, the control spool springs or control shaftcentering spring can always act to return thehandle to “neutral” and re-close the NSS.

iii. The NSS deadband must be narrow enough sothe NSS will open before the unit builds 7 bar (100psi) differential system pressure in either direc-tion.

The neutral start switch is threaded into the spe-cial lock nut for the eccentric plug. Turning theNSS clockwise (CW) into the special nut will movethe NSS closer to the switch cam on the controlshaft, and will narrow the NSS deadband. Turningthe NSS counterclockwise (CCW) out of the spe-cial nut will move the NSS farther from the switchcam on the control shaft, and will widen the NSSdeadband.

1. Using two 1-1/8 inch wrenches, hold the neutralstart switch from turning and loosen the locknut.

2. Disconnect the external control linkage and makecertain the control shaft is in its “neutral” position.

3. Attach a continuity checker to the terminals of theswitch. With the control shaft in its “neutral” posi-tion, turn the switch clockwise (CW) until electricalcontinuity is broken, then turn the switch counter-clockwise (CCW) until electrical continuity is ob-tained. Turn the switch counterclockwise (CCW)an additional 1/4 turn (90°) after continuity hasbeen obtained.

4. Hold the switch in place and tighten the locknut to27 Nm (20 ft•lbf) torque.

5. With the continuity checker attached to the switch,rotate the control handle (or the control shaft) ineach direction to assure continuity is broken whenthe control is not in the “neutral” position.

6. If continuity is obtained in “neutral” and satisfacto-rily interrupted in each direction, proceed to checkthe switch with the prime mover running. Theswitch must open before the unit builds 7 bar (100psi) differential system pressure in either direc-tion.

If the switch opens after the unit builds systempressure in either direction, loosen the switch locknut and turn the switch clockwise (CW) 1⁄12 turn(30°). Tighten the switch lock nut and recheck theswitch operation. Repeat this procedure if neces-sary.

7. If neutral start switch operation is satisfactory,reconnect the external control linkage.

8. If continuity is not interrupted with an equal move-ment of the control handle in each direction,continue with the next section.

3. Position the eccentric plug so the switch pin isoffset toward the control mounting surface. Thiswill provide the best contact between the pin andthe cam on the control shaft.

4. Hold the control shaft in its “neutral” position (inthe center of the control shaft “free-play” area).Locate the switch pin in the slot of the switch camby turning the eccentric plug while checking thepin position (depth) in the plug. When the pinengages the cam slot, the pin will be at its maxi-mum depth in the plug. Hand tighten the plug locknut to hold the eccentric plug in position.

5. Turn the control shaft an equal amount in eitherdirection from “neutral.” The switch pin shouldmove out of the eccentric plug an equal distancewhen the control shaft is turned. Turn the eccen-tric plug to center the switch pin with the cam slot.Only a small amount of adjustment in either direc-tion should be needed to center the pin.

6. While holding the eccentric plug in place, tightenthe eccentric plug lock nut to 27 Nm (20 ft•lbf).Reinstall and adjust the switch as outlined in theprevious section.

NOTE: The eccentric plug normally requiresbetween 5-1/2 and 6-1/2 turns to install into thecontrol housing .

CAUTIONDo not turn the eccentric plug into or out of thehousing beyond specifications.

Checking Switch ContinuityRecheck switch continuity to determine whether addi-tional adjustment of the eccentric plug is necessary.

WARNINGThe following procedure requires the vehicle/machine to be disabled (wheels raised off theground, work function disconnected, etc.) inthe event the pump should go into strokeduring this adjustment.

1. Install two 50 bar (or 1000 psi) gauges in each ofthe displacement control cylinder gauge ports(M4 and M5). Attach a continuity checker to theterminals of the neutral start switch.

2. Energize the starter circuit, and start the primemover.

3. While operating at normal speed and with thepump in its “neutral” (zero flow) position, note thepressure reading on the gauges. This readingshould be noted as the base pressure.

4. Slowly move the control handle in one directionwhile observing the pressure gauges and thecontinuity checker. Continuity must be brokenbefore the pressure on either gauge increasesmore than 0.9 bar (12 psi) from the base pressureobtained at “neutral.”

5. Slowly move the control handle in the oppositedirection. Again, continuity must be broken beforethe gauge pressure increases more than 0.9 bar(12 psi) from base pressure.

6. Continuity must again be verified when the controlis returned to neutral.

7. If continuity is not broken at base pressure plus 0to 0.9 bar (0 to 12 psi) in either direction, stop theprime mover and readjust the eccentric plug asdescribed in the previous section. If the pressuredifference is equal in each direction but greaterthan 0.9 bar (12 psi), loosen the switch locknutand turn the switch clockwise 1/12 turn (30°) toincrease the sensitivity. Retighten the locknut andrecheck pressure differences and continuity.

8. After verifying proper control and switch opera-tion, stop the prime mover. Remove the continuitychecker and pressure gauges. Reinstall the servopressure port plugs and reconnect the electricalleads from the machine starter circuit to the neu-tral start switch. Install and adjust, if necessary,the external control linkage.

8.3.1 Charge Relief Valve Adjustment

Motor charge relief is explained in Sec. 2.6.1.

1. To measure motor charge pressure, install a 50bar (or 1000 psi) pressure gauge in the motorcharge pressure gauge port (M3). Also install agauge to measure case pressure. Operate thesystem with the pump in stroke (forward or re-verse) when measuring motor charge pressure.

2. The following table shows acceptable motor chargepressures for some nominal charge relief valvesettings (see model code at right). These pres-sures assume a reservoir temperature of 49°C(120°F). They are referenced to case pressureand assume a one pump/one motor system.

3. Earlier production Series 90 motors are equippedwith a shim adjustable charge relief valve. Shimkits are available as service items. Adjustment ofthe charge pressure is accomplished by removingthe plug (7/8 inch hex) and changing the shimthickness behind the spring. The plug for this typecharge relief port should be torqued to 68 Nm (50ft•lbf).

Later production Series 90 motors are equippedwith an external screw adjustable charge reliefvalve. Adjustment of charge pressure is accom-plished by loosening the lock nut (with a 1-1/16inch hex wrench for 030 through 100 units, or a 1-5/8 inch hex wrench for 130 through 250 units),and turning the adjustment plug with a largescrewdriver or a 1/2 inch hex wrench. Clockwiserotation of the plug increases the setting, andcounterclockwise rotation decreases the setting(at a rate of approximately 3.4 bar [50 psi] perturn). The lock nut for this type charge relief valveshould be torqued to 52 Nm (38 ft•lbf).

4. Once the desired charge pressure setting isachieved, remove the gauges.

9.1.2 Shaft Seal and Shaft Replacement

Lip type shaft seals are used on Series 90 pumps andmotors. These seals and/or the shafts can be re-placed without major disassembly of the unit. How-ever, replacement usually requires removal of thepump or motor from the machine.

1. Position the pump with the shaft facing up.

NOTE: If the unit is positioned horizontally whenthe shaft is removed, the cylinder block couldmove out of place, making shaft installation diffi-cult.

2. Remove the three or four screws holding theretainer plate and seal carrier to the housing,using a 10 mm hex wrench (030 and 042 units),a 5 mm internal hex wrench (055 through 100units), or a 6 mm internal hex wrench (130 through250 units). Remove the retainer plate.

NOTE: Certain earlier production units use a onepiece retainer plate and seal carrier.

3. After removing the screws, the spring force on theshaft may move the seal carrier out of its bore byapproximately 5 mm (1/4 inch). If the seal carrierdoes not move from its bore after removing thescrews, pry it from its bore as shown and/or lightlytap the end of the shaft with a soft mallet.

4. Remove the O-ring from the seal carrier.

5. Place seal carrier and seal in an arbor press andpress out old seal.

6. Inspect the seal carrier, the new seal and the O-ring for any damage or nicks.

MV Displacement Limiters

9.4.2 Variable Motor DisplacementLimiters

1. Remove the tamper-resistant cap from the dis-placement limiter. Using a 19 mm hex wrench,loosen the seal lock nut and remove the nut.Remove the limiter screw from the motor housingwith a 6 mm internal hex wrench.

2. Install the limiter screw and seal lock nut. Do notinstall a new tamper-resistant cap until the limiterhas been adjusted.

3. The displacement limiter should be initially ad-justed so the motor swashplate contacts the lim-iter screws BEFORE it contacts the internal stops.Hold the swashplate in its maximum or minimumangle position and turn the appropriate limiterscrew clockwise until it contacts the swashplate.Then turn the screw an additional 1/4 turn clock-wise and torque the seal lock nut to 54 Nm (40ft•lbf).

4. Final adjustment of the displacement limitersshould be performed on a test stand. Do not turnthe limiter screws counterclockwise beyondtheir initial adjustment positions.

WARNINGCare should be taken in adjusting displace-ment limiters to avoid undesirable speed con-ditions. The seal lock nut must be retorquedafter every adjustment to prevent an unex-pected change in operating conditions and toprevent external leakage during unit opera-tion.

One full turn of the displacement limiter adjustmentscrew will change the displacement as follows:

5. Following the final adjustment, install new tamperresistant caps.
