SERVICE NOTES:

• Use a clean lubricant (compatible with the working fluid) on all pump components during assembly.• Thoroughly clean the reservoir, suction lines, suction strainer, drain lines, etc. before re-installing the

pump. Most premature pump failures occur when contaminants from a previous failure have not beencompletely removed from the system, or cause for previous failure is still present (i.e. water in oil, filterbypassing, etc.).

• Always fill the case with clean fluid before starting a new or serviced pump (fill as high as inlet portwill allow on a PAVC style pump). For flooded suction, purge air from suction lines by cracking the inletfitting or vent plug on pump body. This should prevent an airlock condition and allow for fasterpriming. Starting the pump slowly by jogging (or turning over engine without allowing it to start) willhelp the pump prime and makes it easier to determine when priming has occurred.

• Check for proper shaft rotation if there is a possibility it may have changed during a system rebuild.• Start pump with an open circuit whenever possible. Reduce the compensator to its minimum setting

during start-up. Cycle the pump on and off stroke while increasing the compensator to its requiredsetting. This will assist in break-in of new components and help purge air from the case.

BASIC TROUBLESHOOTING:

Pump Won’t Prime Note : Pump should prime within 30 seconds. If it does not, STOP!

• Check for proper drive rotation.• Make sure pump shaft is turning (i.e. key at coupling hubs is engaged).• Make sure reservoir is full.• Check for major sources of a suction leak (vent plug open, shaft seal missing (PAVC), flange not tight, pinched

o-ring at flange or pump housing, etc.).

Can’t Build Any Pressure• Make sure pump is primed.• Check alignment, especially on PAVC pumps without “9” option.• Make sure system is not an open circuit. (A pump produces flow, not pressure. It can only limit pressure when

the system requirement is higher than the pump compensator setting.)

Can Only Build A Few Hundred PSI• Compensator is backed all the way out.• Remote/load sense line is vented.• Control orifice is plugged.• Pressure control dart is lodged open.• Torque control plug missing (PAVC).• Wrong compensator spool (PVP).

Pump Won’t Compensate• Differential spring over-compressed (i.e. spring guide dislocated).• Drain line blocked (PAVC).• Pressure control stem vent hole is plugged.• Spool travel hindered.• Control orifice missing (PAVC).• Saturation orifice missing in load sense circuit.

SERVICE NOTES:

• Use a clean lubricant (compatible with the working fluid) on all pump componentsduring assembly.

• Thoroughly clean the reservoir, suction lines, suction strainer, drain lines, etc., beforere-installing the pump. Most premature pump failures occur when contaminantsfrom a previous failure have not been completely removed from the system, orcause for previous failure is still present (i.e. water in oil, bypassing filter, etc.).

• Always fill the case with clean fluid before starting a new or serviced pump (fill ashigh as inlet port will allow on a PAVC style pump). For flooded suction, purge airfrom suction lines by cracking the inlet fitting or vent plug on pump body. This shouldprevent an airlock condition and allow for faster priming.

• Check for proper shaft rotation, if there is a possibility it may have changed duringa system rebuild.

• Start pump with an open circuit whenever possible. Reduce the compensator to itsminimum setting during start-up. Cycle the pump ON and OFF stroke while increasingthe compensator to its required setting. This will assist in break-in of new componentsand help purge air from the case.

These service parts are intended for use in hydraulic pumps. Incorrect installation or assembly of these parts could cause the pump or pumps being repaired to fail in subsequent use, or to operate incorrectly.

The following precautions should be followed:1. All parts should be cleaned and then lightly coated with mineral oil, or another lubricating fluid compatible with the system fluid being used, prior to assembly.2. The pump should be disassembled, repaired, and reassembled in a clean environment.3. Use proper tools to disassemble and reassemble the pump.4. If you are uncertain as to how to install these parts, you should obtain assistance either from a Parker Hannifin distributor, or from the Fluidpower Pump Division.

Introduction:The PVP16 **** 12 series piston pumps are designed to provide long life while operating with HydraulicOil. Refer to catalog 1550/USA for limits. However, should maintenance be required, the followinginstructions should be used for disassembly, replacement of parts, cleaning and assembly.

Note:Prior to any pump disassembly, plug the open ports and clean all dirt from the outside of

the pump.

Prior to assembly all parts should be cleaned and then lightly coated with oil.

Warning:Protective eye wear should be worn during all maintenance procedures.

Notes:

1. Make sure "R" or "L" stamped on port plate (corresponding to rotation) is by antirotation pin.2. Installed depth of item 2 (trunnion pin) below surface of item 35 (housing) to be .050/.100 with swashplate clearance

removed by pressing "in" on pin.3. Installed height of item 14 (servo post) above item 45 (rear cover) to be 1.538/1.534.4. Installed height of item 29 (needle bearing) above item 45 (rear cover) to be .150/.130.5. Illustration shows righthand (CW) rotation pump. Lefthand (CCW) pumps will have inlet and outlet ports reversed with

compensator on outlet side.

Service Notes & Basic Troubleshooting

Service Notes:

� Use a clean lubricant (compatible with the workingfluid) on all pump components during assembly.

� Most premature pump failures occur whencontaminants from a previous failure have not beenremoved from the system, or cause for previousfailure is still present (i.e. water in oil, filterbypassing, etc.)

� Thoroughly clean the reservoir, suction lines, suctionstrainer, drain lines, etc. before re-installing thepump.

� Always fill the pump case with clean fluid beforestarting a new or serviced pump for flooded suction,purge air from suction lines by cracking the inletfitting or vent plug on pump. This should prevent anairlock condition and allow for faster priming.

� Starting the pump slowly by jogging (or turning overengine without allowing it to start) will help the pumpprime and make it easier to determine when priminghas occurred.

� Start pump with an open circuit whenever possible.Reduce the compensator to it's minimum settingduring start-up. Cycle the pump on and off strokewhile increasing the compensator to its requiredsetting.This will assist in break-in of new components andhelp purge air from the case.

Basic Troubleshooting:

Pump Will Not Prime∆ Pump should prime within 30 seconds. If it does not,

STOP.∆ Check for proper drive rotation.∆ Make sure pump shaft is turning (i.e. key at coupling

hubs is engaged).∆ Make sure reservoir is full.∆ Check for major sources of a suction leak (vent plug

open, shaft seal missing (PAVC), flange not tight,pinched O-Ring at flange or pump housing.

Cannot Build Any Pressure∆ Make sure pump is primed.∆ Check alignment, especially on PAVC pumps

without "9" option.∆ Make sure systems is not an open circuit.

A pump produces flow, not pressure. It can onlylimit pressure when the system requirement is higherthan the pump compensator setting.

Can Only Build A Few Hundred PSI∆ Compensator is backed all the way out.∆ The remote or load sense line is vented.∆ Control orifice or spool is plugged.∆ Incorrect compensator spool (PVP).∆ Pressure control dart is lodged open.∆ Torque control plug is missing (PAVC).

Pump Will Not Compensate∆ Differential spring over-compressed (i.e. spring

guide dislocated).∆ Control drain line blocked (PAVC).∆ Pressure control stem vent hole is plugged.∆ Control spool travel is hindered.∆ Control orifice is missing (PAVC).∆ Saturation orifice is missing in load sense circuit.

These service parts are intended for use in hydraulic pumps. Incorrect installation or assembly of these parts could cause the pump or pumps being repaired to fail in subsequent use, or to operate incorrectly.

The following precautions should be followed:1. All parts should be cleaned and then lightly coated with mineral oil, or another lubricating fluid compatible with the system fluid being used, prior to assembly.2. The pump should be disassembled, repaired, and reassembled in a clean environment.3. Use proper tools to disassemble and reassemble the pump.4. If you are uncertain as to how to install these parts, you should obtain assistance either from a Parker Hannifin distributor, or from the Fluidpower Pump Division.
