Major Repair
When the four (4) cap screws (Item 16) are loosened,
the internal spring loading will cause the end cap
(Item 14) to separate slightly. Loosen these screws
evenly to prevent distortion of parts. If separation does
not occur as screws are loosened, tap end cap with soft
hammer until parts separate.
IMPORTANT: All surfaces exposed are critical and
caution must be used to avoid damage.
Note the orientation of housing (Item 9) to end cap
(Item 14). To insure proper assembly scribe a line
across housing and end cap for an assembly guide.

The end cap (Item 14) can now be removed from the
motor, however, be certain that the valve plate (Item 1)
does not fall and become damaged. If the valve plate
tends to lift off with the end cap (Item 14), hold it in place
on the end cap and remove both parts together. If the
valve plate remains on the cylinder block, remove it at
this time.
The end cap is actually an assembly consisting of a
needle bearing which is a press fit in the end cap and
the valve plate locating pin (Item 13). Inspect the bear­
ing (Item 12) and remove if replacement is required.
