Service Manual and Repair Instructions
Take care that the shaft seal is only
tted after the end cap has been screwed
down. If any of those parts are replaced,
the shaft end play must be checked:
drive shaft - bearings - housing - front
cover - end cap.
To check the shaft end play, assemble the
above parts plus the gaskets. The shaft
end play should be from 0.08 to 0.18
mm [0.003 - 0.007 in] for frame sizes 033
- 089 and from 0.15 to 0.3 mm [0.006
- 0.012 in] for frame sizes 119 - 334. If
adjustment is necessary, a shim can be
placed under the bearing race in the end
cap. Disassemble these parts and resume
reassembly procedure.
The tapered bearing can be pressed off
the shaft if required. Be careful not to
damage the seal diameter of the shaft
while removing the bearing.
Remove the thrust plate and set the
pump on the servo housings.
Insert the shaft and bearing assembly
through the cast hole in the swash plate,
allowing the bearing to rest on the cast
leveled edge.
In order to replace the pump shaft, the
stripping operations given under pages
19, 21, 22, 23,24, 25, 27
must be carried out.
