c.
Remove the housing (2) from the shaft. This part is actually an assembly that is being held together by the
friction of an internal O-ring (4). It will normally remain assembled until physically separated.
d.
The bronze sealing ring (5) is also held in place by internal O-ring (6) friction. Work this part free and carefully
slide over the shaft.
NOTE
All of the shaft seal (7) parts have now been removed. It is recommended that this entire shaft
seal (7) be replaced.
e.
To remove the charge pump (10), remove cap screws (8) and washers (9). Before removing the charge pump,
mark its housing and the main pump end cap (25) to insure proper orientation when re-assembling.
CAUTION
Protect exposed surfaces and ports to prevent damage and parts falling into main pump.
