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. 4-73
