The bronze sealing ring (8) is easily damaged and care must be exercised when handling.
The bronze sealing ring (8) is also held in place by internal O-ring (9) friction. Work this part free and carefully
slide over the shaft.
Remove the screws (10) and lift the manifold (11) off the motor end cap (12). Refer to paragraph 4-9.10.2 to
repair the manifold.
Remove all but two of the screws (13) and washers (14) holding the end cap (12) to the housing. Make sure the
two remaining screws are opposite each other.
There is an internal spring loading on the end cap and as the last two screws are loosened, it should begin to
separate from the housing. Loosen these screws alternately until the end cap has fully separated from the
housing, then remove the screws entirely.
The end cap (12) can now be lifted off the motor; however, be certain that the valve plate (16) 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 (17), remove it at this time.
All surfaces exposed are critical and caution must be used to avoid damage.
The end cap (12) is actually an assembly consisting of a tapered bearing race (18) which is a slip fit in the end
cap and the valve plate locating pin (20). These parts should be removed from the end cap. There may or may
not be a shim (21) located under the bearing race which should be removed.
Remove the bronze bearing plate (17) and pilot ring (22) from the cylinder block (23). (If the pilot ring remains
with the bearing plate, remove it at this time.) k. The tapered bearing (19) must now be removed from the shaft.
A bearing puller should be used that will pull against the inner race of the bearing. Protect the cylinder block face
(23) during this operation.
After removal of the bearing (19), slip the spacer (24) out of the bore in the cylinder block (23).
Place the motor in a horizontal position. Slide the cylinder block assembly (25-33) off the shaft (34) while holding
the external end of the shaft.
