PUMP REPAIR
There is a gasket between the charge pump and end cap that should be replaced (refer to Fig. 14).

Figure 15.
The charge relief valve can be inspected by removing the hex plug, spring, and poppet. Remove the shims
from the counterbore of the hex plug. Do not alter these shims unless new parts are used, in which case the
valve must be reshimmed to the proper setting. (refer to Fig. 15).

The removal of the charge check valves requires the use of a drag-link socket (refer to Fig. 16).
These check valves are cartridges and are interchangeable with each other. It is suggested that these check
valves be replaced in pairs (refer to Fig. 17).
Use caution when installing these valves to prevent damage to the O-ring on the cartridge as it is inserted past
the threads (refer to Fig. 18).
