4 EATON Hydraulics Remanufactured Products M-SRSR-MC001-E February 2003

Fluid Power is the most reliable form of power andmotion control, and the most reliable source forpower and motion control systems is Eaton. Formore than 80 years, engineers have chosen Eatonand Vickers brand products for their quality,reliability and high performance features. This samequality and reliability is now available in a completeline of products remanufactured by Eaton Hydraulics.

Today, users are inundated with remanufacturedproducts that resemble Eaton and Vickers brandproducts. “Will fitters” claim these products are “asgood as new” Eaton and Vickers brand products.However, they cannot offer the same highperformance found with Eaton’s GenuineRemanufactured Parts because the parts are not toEaton’s original equipment specifications.

This publication presents Eaton’s remanufacturedproducts and identifies critical areas of performance.We’ll show you the difference between “will fit” andEaton’s Genuine Remanufactured Parts. In the end,you will have a more complete knowledge of theremanufacturing process, as well as a greaterappreciation for the quality and attention given eachand every Genuine Remanufactured Part from EatonHydraulics.

Introduction

EATON Hydraulics Remanufactured Products M-SRSR-MC001-E February 2003 5

Pumps are the heart of any hydraulic system.

So whenever anything goes wrong, it’s usually the pump that gets the blame.

No one knows Eaton’sproducts better thanEaton In fact, it’s unusual for a

pump failure to be caused bya defect in the pump. Mostoften, it’s a symptom ofproblems hidden elsewherein the system.

Typically, 90 to 95 percent of pump failures can beattributed to one or more of the following causes:

Aeration is the presence ofdispersed bubbles of air in asystem’s hydraulic fluid. Animplosion effect occurswhen the compressed airbubbles are subjected tosystem pressure at thepump outlet. This implosioncan cause metal to be pulledfrom the pressure plates,wear plates, etc. damagingboth the hardware and thefluid.

Cavitation occurs whenrestricted inlet flow to thepump creates fluid voids thatimplode causing shocks thatbreak away critical surfacematerial.

Contamination is anymaterial foreign to ahydraulic fluid that has a harmful effect on itsperformance in a system.Contaminants can be solidparticles, liquids, or gases.Most contaminants cause an abrasive action betweenmating components,resulting in accelerated wear and tear.

Excessive heat is a thermalcondition above a specifiedlimit causing fluid quality andviscosity to be affected. Anextreme system duty cycle,aeration, cavitation, over-pressurization, andcontamination are somefactors that contribute toexcessive heat.

Over-pressurizationsubjects a pump to operatingpressures greater than thosefor which it was designed.This often leads topremature failure.

Improper fluid can causeexcessive wear andincreased internal leakage.The lack of antiwearadditives and low viscositymay result in pump siezure.

Each of these conditionsleaves its own “footprint” on parts. If you recognizethese distinctive types ofdamage, you will understandtwo things:

(1) The need for specificcorrective maintenance soan early failure does notsubject you to more andmore downtime; and

(2) How important it is forany remanufacturingprocess to be done byprofessionals who clearlyunderstand whether apart can be reworked and still meet originalequipment standards.

And, no one understandsyour Eaton and Vickers partsbetter than Eaton and ourAuthorized Distributors.

Install quality, not doubt.

Once you’ve made the decision to use aremanufactured product, it’simportant to select one youcan trust. Other reman-ufactured products simplydon’t compare to Eaton’sGenuine RemanufacturedProducts.

Why? Other remanufaturingsources do not use Eaton’sprocesses or testingmethods. Only Eaton’sRemanufactured Productsguarantee 100 percent useof genuine Eaton parts for longer life at ratedconditions. Mostimportantly, only Eatonoffers remanufacturedproducts that continuallymeet Eaton’s originalequipment specifications.

There’s a big differencebetween “will fit” and “will work.”

In this publication, we will point out importantcomponent parts and their affect on overallperformance. Once youunderstand why these parts

are critical, you will knowwhy it is sometimesnecessary to replace a partrather than remanufacture.Likewise, you willunderstand why theremanufacturing process isincomplete if all parts do not meet Eaton’s originalequipment specifications.The problem is most “willfitters” do not understandthese importantperformance standards.That’s why you have noguarantee a “will fit”component will perform toyour expectations. As aresult, you will discover “will fit” parts can adverselyaffect overall systemperformance and machine life.

In contrast, when you selectan Eaton RemanufacturedProduct, you can feelconfident you are installingthe best quality possible.The same engineering,testing and attention to detail that goes into every new Eatonproduct also goes into everyEaton Remanufactured Part,or it isn’t shipped. Eaton’s

Remanufactured Productsare built for long life andcarry a two-year warranty.

Eaton Aftermarket Service Center.

Eaton’s parts areremanufactured at aspecially-dedicated facility inMemphis, Tennessee, witheasy access to an overnightshipping network. Eaton’sexperienced techniciansknow the correct toleranceof every Eaton product aswell as how the parts shouldbe remanufactured toEaton’s original qualityspecifications.

There’s no replacementfor Eaton and VickersRemanufacturedProducts

Introduction

EATON Hydraulics Remanufactured Products M-SRSR-MC001-E February 2003 7

As parts enter ourRemanufactured Products Facility, they’redisassembled and the piecesare inspected against certainspecifications to determine ifthe part can be remanu-factured. If so, the parts arereworked to perform likenew, following the exactsame processes we use inour manufacturing facility.

Eliminate the guesswork.Choose Eaton’s productthe first time and everytime.

When remanufacturedproducts are right for you,purchase Genuine Eaton orVickers RemanufacturedProducts from your localEaton Authorized Distributor.To locate a Distributor visitwww.eatonhydraulics.com.

Our expertise means more value.

Here’s another advantage of dealing only with Eaton’sAuthorized Distributors.When you return your coreto be remanufactured, your Eaton and/or Vickersdistributor can inspect it to see if there is a systemproblem that should becorrected. If contamination

is part of the problem, askyour Authorized Distributor to explain how using VickersContamination Controlproducts can help improveyour system reliability andextend the warranty of yourremanufactured product for one additional year.

Look for the GenuineRemanufactured PartsSeal.

It’s on each and every part we remanufacture. And it’s your assurance that the part has been diagnosed,remanufactured and tested to meet Eaton’s higheststandards for performance. If you receive a “Vickers” or “Eaton” product in a boxthat doesn’t carry this seal,it’s not a GenuineRemanufactured Productfrom Eaton.

Vickers Vane Pumps

Principles of operation

In intra-vane pumps, aslotted rotor is splined to thedrive shaft and turns inside acam ring. Vanes are fitted tothe rotor slots and follow theinner surface of the cam ringas the rotor turns. Centrifugalforce and pressure under thevanes hold them out againstthe cam ring. Pumpingchambers are formedbetween the vanes and thecam ring and are enclosed by the two end plates.

Outlet pressure is constantlyapplied to the small intra-vane area of the vane. As thepump vane rotates throughthe high and low quadrants,outlet pressure is alternatelyapplied to the rest of theunder vane area. This varyingpressure under the vanereduces wear and increasespump efficiency.

Critical parts

Certain parts are critical tothe proper operation of avane pump.The contactbetween the ring surface andvane tips means that bothare subject to wear. To

maintain a constant degreeof contact, the vanes comefarther out of their slots as they wear down.

If the remanufacturingprocess does not provide thesame tolerances, materialsand surface treatments asnew, you may experienceany one or many of thefollowing:• Reduced pump output• Higher power

requirements• Loss of parts durability• Increased noise• Excessive heat generation• Generation of

contaminants• Shortened life• Catastrophic failure

The adverse effects of theseproblems are compoundedwhen they also affect the integrity of othercomponents as well assystem performance. Thebottom line becomessubstandard performanceand less uptime.

Vickers Vane Pumps

B: Rotors

An old rotor will frequently have wider slots due tovane instability and/ornormal wear over theservice life of thecomponent. In “will fit”products, rotor slot width isa critical dimension whichwe often find out of spec.“Will-fitters” willoccasionally try to usethicker vanes to compensatefor wider rotor slots. Ifthicker vanes are used,there may be higher vane tiploading on the ring contourand excessive ring wearcould develop and result inearly failure.

A: Flex Plates (VQ)

The depth of metering andtiming notches andlubrication grooves plays avital role in VQ pumpoperation. As these steel-backed bronze plates flex,they eliminate the potentialfor pump seizure during coldstart-up or at higherpressures. “Will fitters”often replace these plateswith “look-alikes” withoutthe same materialcomposition. The result…erosion that generatescontamination or ineffectiveprotection against seizure. Ifplates are not made of thecorrect blend of materials,they will not “flex” properly.This can result in high heatand low volumetricefficiency.

C: Vanes

Vane tip radius is veryimportant in maintaining the proper vane tip-to-ringcontact pattern. Almost all used vanes cannot be reworked withoutweakening them or causingexcessive contact stressbetween the vane and thecam ring. All vanes in a pumpshould be the same length. Ifthey are not, vane breakagewill occur and pumps willseize immediately. Eatonuses new vanes in all Vickersremanufactured vane pumpcartridge kits.

D: Rings

Ring contour, slope and dwellangles are critical and involveintricate machining and closetolerances. “Will fit” ringsoften do not maintain therequired dwell angles at theminor diameter area. Thiscauses irregular vaneoperation which can lead tovane instability and excessiverotor slot wear.

Often, the contoured ringsurfaces are not properlytreated and premature wearis inevitable. This, in turn,causes internal leakage,adversely affecting overallperformance. Also, if ringwear becomes excessive,contaminants can beintroduced into the system.The tolerance between therotor and ring thickness isalso very critical. If thistolerance is not maintained,either excessive leakage orinadequate lubrication willcause excessive heat whichin turn willl lead to loss offlow or seizure.

Vickers Vane Pumps

E: Pressure Plate/Wear Plate (VHO)

The depth of metering and timing notches andlubrication grooves, as wellas surface treatment in VHOwear/pressure plates, plays a vital role in pumpoperation. Metering notchesat the inlet/outlet ports aresynchronized with the dwellangles in the pump ring inorder to provide a smoothertransition of the vanes asthey move from inlet, tooutlet, to inlet. If “willfitters” grind these notches and grooves out of tolerance, the vanes willvibrate causing higher noiseand increased internalleakage which will result inlower volumetric efficiency.

If surface treatment of the plates is not tospecification, the film of oilthat should be presentbetween the wear plate,rotor and pressure platediminishes and pumpperformance deteriorates.

F: Bodies

Body surfaces in V10/V20square pumps can bereworked to some extent.However, the 0-ring groovedepth is very crucial andmust be maintained. Surfacetreatment/hardness must beto specification for properpump efficiency. Bearing andshaft seal bore diametersmust be within tolerance.Any deviation in thedimensions will causepremature failure.

Eaton andVickers PistonPumps

Principles of operation

In axial piston pumps, thepistons reciprocate parallel tothe axis of rotation of thecylinder block. The simplesttype of axial piston pump isthe swash plate in-linedesign.

The cylinder block in thispump is turned by the driveshaft. Pistons fitted to boresin the cylinder block areconnected through pistonshoes and a shoe plate, sothat the shoes bear againstan angled swash plate.

As the block turns, the pistonshoes follow the swashplate, causing the pistons toreciprocate. The ports arearranged in the valve plate so that the pistons pass theinlet as they are pulled outand pass the outlet as theyare forced back in.

The displacement of axialpiston pumps is determinedby the size and number ofpistons, as well as the strokelength which is determinedby the angle of the swashplate.

In variable displacementmodels of the in-line pump,the swash plate is installedin a movable yoke.

“Pivoting” the yoke onpintles changes the swashplate angle to increase ordecrease the piston stroke.

Critical parts

Eaton and Vickers axial pistonpumps are highly efficientunits, available in a widerange of capacities. Theirparts are closely fitted andsurfaces finely machined.

Certain parts and clearancesare critical to the properoperation of a piston pump.If the remanufacturingprocess does not provide thesame tolerances, materialsand surface treatments asnew, you may experienceany one or many of thefollowing:• Reduced pump output• Higher power requirements• Loss of parts durability• Increased noise• Excessive heat generation• Generation of contaminants

The adverse effects of theseproblems are compoundedwhen they also affect theintegrity of other systemcomponents as well assystem performance. Thebottom line becomessubstandard performanceand less uptime.

Eaton andVickers PistonPumps

Piston Pump Rotating Group

The most critical element inpiston pump operation is therotating group. Some keyparts of the rotating groupare the cylinder block, valveplate and piston shoe sub-assembly.Most “will fitters” do notattempt to rework Eaton andVickers piston pumps. The few rotating groups that arereworked by “will fitters”generally do not provide the same overall life as ourgenuine remanufacturedrotating groups, becauseoriginal tolerances areseldom maintained.Often, will-fit rotating groupsfail due to heavy internalleakage which results in highsystem temperature. Thesefactors lower the volumetricefficiency of any given pump,and the adverse effects areeven more dramatic at higherpressures.

A. Cylinder Block

Cylinder block boredimensions are veryimportant. Boreconcentricity and diameterare two key areas. Cylinderblock face-flatness is alsoimportant and requiresspecial treatment. “Willfitters” seldom meetrequired dimensionaltolerances and surfacetreatment is frequentlysubstandard. This leads to poor pump efficiency.

C. Piston Pump Valve Plate

The valve plate in a piston unit is somewhat like thewear/pressure/flex plates in a vane pump. Themetering and timingnotches on the plate arevery critical from anoperational point of view.Most “will fitters” try torework old plates, but do not always maintain correctdimensions. Surfacetreatment, or lack of, isgenerally a problem. A re-worked plate can end upwith a poor surface finish,which causes heavyinternal leakage and,consequently, reducedvolumetric efficiency.

B. Piston Shoe Sub-Assembly

Piston diameters, inconjunction with cylinderblock bore diameters, alsoplay a key role in providingoptimum piston pumpefficiency. If pistondiameters are out oftolerance, there is either high internal leakage, or theopposite…metal-to-metalscuffing or fusion.The way piston shoes areswaged to the pistons isalso of prime importance.The shoe cannot be tooloose or too tight. All shoeheights must be withincertain limits to avoid shoelifting and rolling.

SystemicContaminationControl

For Reliable Performance, Depend on Eaton and

Vickers Brands for Quality Contamination Control

Systemic Contamination Control and Eaton’s GenuineRemanufactured Products

Eaton has determined that the cause of 80 percent of allhydraulic equipment failures is inadequate contaminationcontrol practices. The goal of the Vickers SystemicContamination Control Program is to clean the fluid to thepoint at which contamination is no longer a factor in thefailure of the system, during the desired useful life of thesystem. The easy to follow Systemic Contamination Controlthree-step approach involves:

Step 1. Setting a target cleanliness level for the system;

Step 2. Selecting filters and filter placements to achieve the target;

Step 3. Sampling fluid to confirm achievement of the target cleanliness level.

Vickers fluid analysis service can provide a thorough analysis of your systems fluid. The analysis will not onlyprovide information on the amount of contamination in thesystem, but also what the contamination is so the source of the contamination can be found and eliminated.

Because of the superior quality and reliability of Eaton’sgenuine remanufactured products, Eaton has elected toinclude these products under the Systemic ContaminationControl Extended Warranty Program. Eaton will extend, byone year, the standard warranty on all Eaton and Vickersremanufactured products used in a system that is protectedby Vickers filters (and elements) applied consistently withthe principles presented in the Guide to SystemicContamination Control (561).
