PUMP REPAIR
Do not reuse the screw holding the spring to the servo piston as it has a nylon-locking insert that is not effective
when reused. These springs should not be removed unless necessary (refer to Fig. 29).
Figure 29.
Figure 30.
The trunnions should be marked to insure reassembly to the correct side of the housing (refer to Fig. 30).
Remove the hex head screws from each trunnion (refer to Fig. 31).

Friction caused by the O-ring on the trunnion can make it necessary to drive the trunnion assembly out of the
housing (refer to Fig. 32 and 33).
