GENERAL INSTRUCTION
Preliminary
Any servicing work done on main pump is to be done in a clean environment to prevent potential
contamination by foreign particles.
Appropriate tools and equipment are required in order to insure proper disassembly and
reassembly in suitable conditions. In case of repetitive service, a specific working bench is
recommended.
To prevent oil leakage and body tilting during assembly, housing bolts are to be tightened as per
the following pattern !

Rotor :
Side surfaces and vane slots should be free of scratches. Side feeds, vane slots and holdout pin
orifices should be free of any contamination. Serration(driving splines) should not be deformed
by the shaft.
③
③
Parts
Parts must be kept clean at all time. If cleaning is needed, solvent is to be used. It is needed to
check and oil the inner parts before assembly.
In case of replacement of parts with mulitiple numbers, such as vanes and holdout pins, all the
parts are to be changed.
Vanes
The faces and edges should be free of scratch from contamination. Vanes should move
smoothly in the rotor slots, without excessive clearance. Edges may be stoned with a fine lndia
stone to remove burrs.
Vane holdout pins :
Holdout pins should have no matting marks.

Camring :
No scratches or vane shock marks(waves) should be seen. Visual axial waves on new camring
are from grinding process and therefore normal.
④
④
Port plates :
Faces should not be scratched. No cavitation/aeration/fretting corrosion marks should be seen.
When there, the bronze bushing should be clean, with no abnormal wear sign.
Bi-directional cartridges use same port plates for CW and CCW rotation. Unit-directional
cartridges require different port plates.
⑤
⑤
Seals :
All oil seals must be cleaned, with no wear or cutting mark. When servicing a pump from field
operation, it is highly recommended to change all seals. All seals are to be greased lightly
before assembly.
Use seal driver tool to install shaft seal, and protective cone to install shaft assembly.
Backup rings(1) on pressure plates are to be replaced, anytime a cartridge is taken out of a
pump. Backup rings are to be installed as follow, behind the square seal :

Back up ring Seal
Shaft :
Key-way should be clean and not worn on the sides by excessive torque. No fretting corrosion
due to poor coupling should be visible. On spline shaft, splines should not be deformed.
No axial scratch should be on the sealing area(1). The shaft seal lip contact line may be visible,
but should not be a groove. Bronze-bushing contact area(2) should be clean and cylindrical,
without scratch marks.

Ball bearing(3) should turn freely and snap ring(4) should be in place. Some shaft assemblies
have 2 snap rings, before and after the ball bearing.
Never insert a snap ring from shaft seal side, to avoid scratching the sealing surface.
Use protective cone to install shaft assembly. If not available, make sure not to damaged the
shaft seal lips.
Pre start check and priming.
Before operating the pump again, the following points are to be checked :
Pump rotation is as per electric motor or engine.
All fittings are properly connected and tight. No oil-leak and/or air intake being allowed.
If any, valve on suction line is to be fully opened.
When electric motor or engine is started up, the pump should prime immediately. However,
depending on installation and amount of air in the discharge lines, priming may take a few
seconds.
In case priming does not occur within 15 seconds, equipment should be switched off at once.
Then :
Manually fill the pump housing with fluid.
Bleed off air that may be trapped in the pump.
Check air bleed-off valves.
Start rotation in a jogging manner until a prime is picked up.
