Inspect the inner race of ball bearing (13, fig. 3-4) for galling or roughness If no damage
is apparent and if no damage was observed when the outer race was inspected, then it is not necessary
to remove the inner race from the shaft. If damage to either the inner or outer race is observed, both
must be replaced. The inner and outer races are serviceable as a matched set only. Remove retainer
ring (12). Slip inner face from pump shaft (53).
Assemble Hydraulic Pump.
Inspect pump shaft (53, fig. 3-4) for excess wear or damage. If either spline shows dam-
age or if bearing journal or seal surface shows galling, scoring or heat discoloration, replace shaft.
If inner and outer races of ball bearing (13) are not damaged or won, assemble inner
race on shaft (53) with retaining ring (12) using snapring pliers. If either inner or outer race is damaged,
replace bearing as a set only. Install new inner race as described above.
If previously removed, install inner retainer ring (47). Inspect old ball bearing. If galled
or damaged, press new ball bearing (48) on pump shaft. Ball bearing (48) should seat against inner
retainer ring (47).
Be sure not to deform inner retainer ring by forcing
ball bearing (48) against it. If deformed, back ball
bearing (48) off and reseat.
Care should be taken to support inner race of ball bearing (48) in arbor press while pressing in pump
shaft (53). Heating the ball bearing in hot oil will aid in a smooth bearing installation. Install outer
retaining ring (47).
