Start Disassembly HereCAUTION:1. If prying off sections becomes necessary, take extreme care not to mar or damage machined surfaces. Excessive force while prying

can result in misalignment and seriously damage parts.

2. If parts are difficult to fit during assembly, tap gently with a soft hammer (never use an iron hammer).

3. Gears are closely matched, therefore they must be kept together as sets when removed from a unit. Handle with care to avoiddamage to the journals or teeth. Avoid touching gear journals.

4. Never hammer bushings into bores; use an arbor press.

1) Place the pump in avise with the drive shaftpointIng down. Caution:DO NOT GRIP ON ORNEAR ANY MACHINEDSURFACES DURINGASSEMBLY ORDISASSEMBLY.Match-mark all sections.Be sure to align thesemarks whenreassembling.

4) Remove the thrustplate. Examine andreplace if necessary.See wear guide page 10.

5) Carefully remove thedrive and driven gears.Avoid tapping the gear teethtogether or against otherhardened surfaces. Keepthese gears togetherbecause they are a matchedset. Examine and replace ifnecessary. (See page 10).Remove the thrust platefrom the bearing carrier.Examine and replace ifnecessary.

For multiple assemblies only

6) Lift the gear housingfrom the bearing carrier.If prying is necessary,take care not to damagemachined surfaces.Examine and replaceif necessary.(See page 10)

For multiple assembliesonly

2) Use a socket wrenchto remove the 4 capscrews on single units orthe 4 hex nuts, studsand washers of multipleunits.

3) Lift off the port endcover. If prying isnecessary, be careful notto damage the machinedsurfaces. Dowel pins willremain in either the portend cover or the gearhousing.



7) Carefully lift or pry offthe bearing carrier toprevent damage tocontact face and edges.Dowel pins will remain ineither the bearing carrieror the gear housing.DO NOT REMOVE THEM.

For multiple assemblies only

8) Remove theconnecting shaft.Remove the thrust plate.Examine and replace ifnecessary. (See page10). Remove the drivengear and the integral gearand drive shaft. Keepthese together as theyare a matched set.Examine and replace ifnecessary. (*See page10). Be careful not todamage the machinedsurfaces of the gears.

9) Lift or pry off the firstsection gear housing. Becareful not to damagemachined surfaces.Examine and replace ifnecessary (see page 10).

13) Grip the shaft endcover in a vise with themounting face down.Remove double lip sealby inserting the specialseal removal tool (seeTool List) into the notchbetween the double lipseal and the shaft endcover. Tap the seal outand discard.

Remove and discard allrubber and polymer seals.

12) Use a bearing pullerto remove the outboardbearing.

10) Inspect all bushingsfor scoring ordiscoloration andreplace if necessary.Use a bushing puller asshown in the tool list toremove bushings (seepage 4).

11) If the pump isequipped with anoutboard bearing, placethe shaft end cover inthe vise with themounting face up.Remove the snap ringwith snap ring pliers. If aunit is equipped with aspiral-lock retaining ring,remove with a smallscrewdriver or awl.



Start Assembly Here1) Stone all machinedsurfaces with a mediumgrit carborundurn stone.

2) If the bushings havebeen removed, deburrthe bushing bores with anemery cloth. Rinse partsin a solvent. Air blast allthe parts and wipe witha clean, lintless clothbefore starting assembly.

3) Grip shaft end cover invise with mounting facedown. Examine plug orplugs* to be sure they'retightly in place.Replacement is necessaryonly if parts are damaged.Remove with screwdriver.

*PGP/PGM315 and 330have two plugs in both theshaft end and port endcovers. PGP/PGM350 and365 have one plug on theoutlet side of their shaft endand port end covers.

7) Repeat Steps 1 and 2,stone and rinse parts.

5) Note: Assembly steps 5, 6, 7 & 8apply to shaft end cover, bearingcarrier and portend cover.Any bushings removed from theshaft end cover, portend coveror bearing carrier should beassembled in the drive bores withthe groove to the top of unit (12o'clock). Assemble the bushings inthe driven bores with the groove tothe bottom of the unit (6 o'clock).The PGP/PGM315 does not havegrooved bushings, therefore thebushing seams should be placedat the 12 and 6 o'clock positions.

8) See that dowel pinsare in place in any newcastings. Examine all ofthe dowels. Beforeinserting, make certainthat the hole is clean andfree from burrs. Gentlystart the pin straight intothe hole and tap lightlywith a soft hammer.

4) New plugs should bescrewed in tightly. Stakethe plug with a prickpunch at both ends of thescrewdriver slot andaround edges. Peen theedge of the hole 1/32" to1/16" with a1-1/2"diameter steel ball.NOTE: If new plug orplugs are being installed,coat threads withLoctiteTM thread sealant.

6) Bushings should bepressed into the bores,one at a time, using thespecial installation tooland an arbor press. Besure the that the grooves(or seams) are positionedas stated in Step #5. Thebushings must be pressedinto the bores flush withthe casting face. Be sureto support the castingsso that they are squareand level.



9) Before inserting a new lipseal in the shaft end cover,coat the outer edge of thelip seal and its recess withPermatex AviationForm-A-Gasket™ No. 3non-hardening sealant orequivalent. With the metalside of the lip seal up, pressit into the mounting flangeside of the shaft end coverwith an arbor press and bar(see Tool List on page 4).Be careful not to damagethe lip of the seal. Press inuntil flush with the recess.Wipe off excess sealant.

10) If the unit is equippedwith an outboard bearing,guide the bearing into itsrecess in the shaft endcover. This is a lightpress fit. It may benecessary to lightly tapthe bearing into thebore.

11) Install the snap ring inthe groove to retain theoutboard bearing.

12) Grease the new gasketseals and insert them intothe grooves in both sides ofall gear housings. Positionthe first gear housing overthe shaft end cover anddowels. Tap it with a softhammer until it rests tightlyagainst the shaft end cover.Be careful not to pinch thegasket seal. Also be surethat the large rounded coreis on the inlet side.

16) Slip the thrust platewith the seal over the gearjournals and into thehousing bore. The flat sideof the seal should face upwith the relief groovefacing the outlet side. (Forsingle pump assembliesgo directly to Step #21).

15) Slide the driven gearthrough the housing and intothe bushing in the shaft endcover. Coat the steel sleevetool with grease. Place thelightly-greased drive shaftinside the sleeve and slideboth through the shaft endcover with a twisting motion,until the integral gear restsagainst the thrust plate.Avoid damaging the doublelip seal. Remove the steelsleeve. Squirt clean oil overthe gears.

14) Gently slip the thrustplate through the gearhousing and into place onthe shaft end cover. Thechannel seal from Step#13 should face the shaftend cover. The reliefgroove in the plate shouldface the outlet side of thepump.

13) Assemble the channelseals into the grooves inthe thrust plates with theflat side of the seal facingaway from the thrust plateas shown below.

ThrustPlate



17) Place the bearingcarrier onto the journalsof the drive and drivengears. Be sure to line upthe dowel holes over thedowel pins. When theparts are parallel,squeeze them togetheror alternately tap overeach dowel until theparts are together.

18) Insert the connectingshaft into the spline ofthe drive gear. Positionand place the secondgear housing on thebearing carrier asoutlined in Step #12.


19) Place the thrust platein the gear housing perStep #14. Insert the driveand driven gears of thesecond section in theirrespective bearings. Makecertain the gears are incontact with the thrustplate face. Place the portend cover plate in thehousing per Step #16.


20) Check the plug orplugs in the port endcover to be sure thatthey are tight. Follow theprocedure outlined inStep #4 for new plugs.For multiple assembliesonly

22) Thread the fastenersinto the shaft end coverand tighten alternately orcross corner. Rotate thedrive shaft with a 6"wrench to check forbinding. If there is nointernal binding, torquediagonally opposedfasteners to 200 ft. lbs.(2400 in. lbs.); 141 ft. lbs.(1700 in. lbs.) for PGP/PGM315 models; 450 ft.lbs. (5400 in lbs.) for PGP/PGM365.

21) Place the port endcover over the gearjournals. Align the dowelswith the holes in themating casting. Beingcareful not to pinch thegasket-seal, tap the portend cover lightly in thecenter between bearingbores to engage thedowels and to move partstogether in the finalseating.



Guideline for acceptable wear

Gear Housings

Wear in excess of .007" cut-out necessitatesreplacement of the gear housing. Place a straight-edgeacross bore. If you can slip a .007 feeler gage under

the straight-edge in the cut-out area, replacethe gear housing.

Pressure pushes the gears against thehousing on the low pressure side. As thehubs and bushings wear, the cut-out

becomes more pronounced. Excessivecut-out in a short period of time indicates excessivepressure or oil contamination. If the relief valve settingsare within prescribed limits, check for shock pressuresor tampering.When the cut-out is moderate, 007" or less, the gearhousing is in good condition and may be reused.

Gears

Any scoring on gear hubs necessitatesreplacement. Scoring, grooving, or

burring of the outside diameter of theteeth requires replacement. Nicking,

grooving, or fretting of teeth surfaces alsonecessitates replacement.

Drive Shafts

Replace if there is any weardetectable by touch in the seal

area or at the drive coupling. Themaximum allowable wear is .002".

Wear in the shaft seal area indicates oilcontamination. Wear or damage to splines, keys,or keyways necessitates replacement.

Thrust Plates

The thrust plates seal the gear section atthe sides of the gears. Wear here will allowinternal slippage, that is, oil will bypasswithin the pump.

A maximum of .002" wear is allowable. Replacethrust plates if they are scored, eroded or pitted.

Check center of thrust plates where the gears mesh.Erosion here indicates oil contamination.Pitted thrust plates indicate cavitation or oil aeration.Discolored thrust plates indicate overheating, likely dueto insufficient oil.

Dowel Pins

If either the dowel or dowel hole is damaged,the dowel or machined casting, or both, mustbe replaced.

If more than reasonable force is required toseat dowels, the cause may be poorly deburred

or dirty parts; cocking of the dowel in the hole orimproper pin-to-hole fit.

Bushings

If gears are replaced, bushings must bereplaced. Bushings should fit into the bore witha heavy press fit.

Seals and Gaskets

Replace all rubber and polymer seals,including all "0" rings, thrust plate channel

seals, shaft seal and gasket seals.

Plugs

Examine the plugs in the shaft end and portend cover to make sure that they are in the

proper position and tight. The PGP/PGM315 andPGP/PGM330 should have two plugs in both theshaft end and port end in tandem units only. ThePGP/PGM350 and PGP/PGM365 have one plug intheir shaft and port ends high pressure side only.



Lubrication and OilRecommendationsAll parts, with the exception of the outboard bearing,are lubricated by the hydraulic oil in the circuit.Particular attention must be paid to keep clean oil inthe circuit system. Whenever there is a pump ormotor failure, and there is reason to feel that metalparticles may be in the system, the oil must bedrained, the entire system flushed clean and anyfilter screens thoroughly cleaned or replaced. New oilshould be supplied for the entire system. Oil suitableand recommended for use in circuits involvingParker's pumps and motors should meet the followingspecifications:

Viscosity: • 50 SSU minimum @ operating temperature 7500 SSU maximum @ starting temperature

• 150 to 225 SSU @ 100° F. (37.8°C.) (generally) 44 to 48 SSU @ 210° F. (98.9° C.) (generally)

Viscosity Index: 90 minimum

Aniline Point: 175 minimum

Recommended Additives: Foam depressant,rust and oxidation inhibitors. Filtration: 10 micronrecommended for maximum pump life.

Other Desirable Characteristics:

• Stability of physical and chemical characteristics.

• High demulsibility (low emulsibility) for separationof water, air and contaminants.

• Resistant to the formation of gums, sludges, acids,tars and varnishes.

• High lubricity and film strength.

General Recommendations:

A good-quality hydraulic oil conforming to thecharacteristics listed above is essential to thesatisfactory performance and long life of anyhydraulic system.

The oil should be changed on regular schedules inaccordance with the manufacturer's recommendations,and the system periodically flushed.

The oil temperature in the reservoir must not exceed200° F., (93.3° C.) with a maximum temperature of180° F. (82.2° C.) recommended. Higher temperatureswill result in rapid oil deterioration.

Reservoir capacity should equal in gallons the pumpoutput in gpm or the total gpm of all pumps, wherethere is more than one in the system.

Oil poured into the reservoir should pass through a100-mesh screen. Pour only clean oil from cleancontainers into the reservoir. A 100-mesh screen maybe used in the suction line leading to the pump. Asuction filter should be of sufficient size to handletwice the pump capacity. It must be cleaned andchecked regularly to avoid damage due tocontamination and cavitation.

Normal Temperatures:

O° F. (-1 8° C.) to 100° F. (37.8° C.) Ambient 100° F.(37.8° C.) to 180° F. (82.2° C.) System. Be sure youroil is recommended for the temperatures you expect toencounter.

Cold Weather Operation:

Oils for use in cold weather should have a viscositynot exceeding 7500 SSU at the minimum start-uptemperature. A pour point of at least 20° F. belowstart-up temperature is recommended. Start-upprocedures should allow for a gradual warm-up untilthe oil reaches a reasonably fluid state.

The Use of Other Fluids:

• Automatic Transmission Fluid (ATF): In general, ATFperformance is satisfactory; however these fluids aresometimes too expensive for normal use in hydraulicsystems.

• Diesel Fuel or Kerosene (Coal Oil): Thoughsometimes used as dilutants for cold weatheroperations, they are not recommended, as theyare not sufficiently refined.

• Fire Resistant Fluids: DO NOT USE ANY FIRERESISTANT FLUIDS OR NON-PETROLEUM OILSWITHOUT CONSULTING OUR TECHNICAL SERVICEDEPARTMENT.

Recommended Start-upProcedure For New orRebuilt PumpBefore installing a new or rebuilt pump, back offthe main relief valve until the spring tension on theadjusting screw is relieved. This will avoid thepossibility of immediate damage to the replacementunit in the event that the relief valve setting hadbeen increased beyond the recommended operatingpressure, prior to removing the old unit.

Before connecting any lines to the pump, fill all portswith clean oil to provide initial lubrication. This isparticularly important if the unit is located above theoil reservoir.

After connecting the lines and mounting thereplacement unit, operate the pump at least twominutes at no load and at low rpm (400 min.) Duringthis break-in period, the unit should run free and notdevelop an excessive amount of heat. If the unitoperates properly, speed and pressure can then beincreased to normal operating settings.

Reset the main relief valve to its proper setting whilethe pump is running at maximum operating engine(motor) speed for the vehicle.

ALWAYS USE AN ACCURATE GAUGE

RecommendedTest ProcedureMake certain that there is an adequate supply of oil forthe pump; at least one gallon of oiI for each gpm ofpump capacity.

If one section of a tandem pump is being tested,make sure that all other sections not being testedare adequately supplied with oil. If any of the othersections run dry, or if plugs are left in ports, seriousand permanent damage will result.

The oil should be a good quality hydraulic oil rated at150 SSU at 100° F., with the oil temperature held at120° F. plus or minus 50° F. (Test procedures aredescribed in detail in SAE handbooks; see HydraulicPower Pump Test Procedure, SAE J745c.)

The feed line must be of adequate size with no morethan 5" mercury vacuum adjacent to the pump inlet. Asa rule, the feed line must provide a feed flow velocitynot in excess of 8 feet per second.

Feeding hot oil into a cold pump may cause the pumpto seize. Jog the pump by momentarily starting andstopping repeatedly the driving engine or motor togradually equalize pump and oil temperatures.

Run the pump at least two minutes at no load andmoderate speed (not over 1500 rpm). If the pumpbecomes excessively hot, shut down immediately andlocate the problem source.

Gradually increase pressure on pump, in 500 psiincrements until the desired test pressure has beenreached. This should take about five minutes.

Delivery should run close to rated catalog performancefigures, which are averaged from testing severalpumps. A 5% lower reading may be used as a ratedminimum if new or relatively new parts have beenused. When rebuilding the pump with parts from theoriginal pump, which, while worn, appear satisfactoryfor reuse, a 10% or 15% lower reading may bepermitted, depending on the performance expectedfrom the equipment. One's own experience will provethe best guide here.

Many repairmen measure the output at normaloperating speed and at zero pressure, then again at1000 psi (or the operating pressure of the equipment)and allow a volume decrease approximating the listingbelow. It is a suggested reference only which makesallowance for reused parts.

At test speeds other than 1800 rpm, gpm delivery willvary almost proportionately, but the same (drop-off)figures should be used.

Be sure to run the pump in the direction for which itwas designed and built. Driving the pump in the wrongdirection will build up pressure behind the shaft seal,damaging it and necessitating replacement.

After completing testing procedures, the pump isready for installation and immediate duty operationon equipment. Again, it must be remembered thatto prevent seizure, hot oil must not be fed into acold pump.
