8. DISMANTLING ­ REASSEMBLY (continued)
When the end­plate is free on the shaft, hold it by hand sup­
porting it.
Once the end­plate is out, the rotating part 697 of the mecha­

friction face.

8.2 Dismantling on drive side

Uncouple the pump by removing the coupling.
Remove the key 508 and clean the end shaft. Then proceed
in the same way as when dismountling on the other side. It is
necessary to push cover 705 slightly a side to avoid damaging
O­ring 707 on key.
Unscrew the screws 723A, remove the cover 705 with its seal
714A taking care not damaging seal 707.
Remove the circlip 537.
Operate then in a identical way in § D
.
TO DRIVE SYSTEM
Open the pump on one side or the other.
Remove the vanes 317.
Check for wear (see § M
AINTENANCE
If vane wear is abnormal, check surface condition of body and of
end­plate faces.
Refit the vanes (new if necessary) respecting the direction of
assembly and check that they slide freely.
Reassemble the pump and check that it rotates freely when turned
by hand.

and its seal 605 are in the front cover 401 and the rotating
part 697 is on the shaft. Then, position the front cover 401 on
the shaft and approach it as far as possible by hand.
Finish fitting the end­plate, screwing the 2 nuts 412 gradually
on to the 2 screws 411.
Make sure that end­plate is centred while screwing.
When the end­plate is in place, remove the screws 411 and
their nuts 412 and screw them up taking care to position one
of the drainage port L pointing down.
Replace the screws 410.
Remove the cover 712 or 705.
Replace the circlip 537.
Replace the cover 705 or 712 with its seal 707 after check
