MOTOR REPAIR
The end cap can now be lifted off the motor; however, be certain that the valve plate does not fall and become
damaged. If the valve plate tends to lift off with the end cap, hold it in place on the end cap and remove both
parts together. If the valve plate remains on the bearing plate, remove it at this time (refer to Fig. 5).
CAUTION
All surfaces exposed are critical and caution must be used to avoid damage.
Figure 5.
Figure 7.
The end cap is actually an assembly consisting of a tapered bearing race (which is a slip fit in the end cap) and
the valve plate locating pin. These parts should be removed from the end cap. There may or may not be a
shim located under the bearing race which should be removed (refer to Fig. 6).
Remove the bronze bearing plate and pilot ring from the cylinder block (refer to Fig. 7).
If the pilot ring remains with the bearing plate, remove it at this time (refer to Fig. 8).
Note that the valve plate has four tapered slots, two at the top and two at the bottom. These four slots identify
it as a motor valve plate and it is not interchangeable with the pump valve plate (refer to Fig. 9).
