NOTE: The charge pump rotation is determined by the
orientation of the gerotor assembly outer eccentric ring
and the location of the alignment pin in the end cap.
Install the inner port plate and the gerotor assembly
outer ring.
Install the alignment pin to properly orientate the port
plates and outer eccentric ring for correct pump rotation.
Install the gerotor assembly.
Install the outer port plate.
Install the spacer plate (if used).
Install the charge pump drive key into the charge pump
shaft.
NOTE: The 75 cc and 100 cc pumps use the same
charge pump drive shaft. Two keyways are provided in
the drive shaft for the later production charge pumps
used in these units. The rear keyway (with identifier
groove) is used in 75 cc pumps. The front keyway
(closest to the internally splined end of the shaft) is
used in 100 cc pumps.
Install the charge pump shaft. The internally splined
end of the shaft is installed next to the end cap.
NOTE: The outer diameter of the front (internally
splined) end of the earlier production charge pump
shafts is chamfered. Earlier production pump end caps
may not be machined to accept the current (non-
chamfered) shaft. Always use a chamfered end shaft in
units with the earlier end cap.
For pumps with an auxiliary mounting pad, install the
auxiliary drive coupling.
Carefully remove alignment pin from cavity without
disturbing aligned parts. Using petroleum jelly place pin
in charge pump cover.
Install charge pump cover with aligning pin into the
aligned parts in the cavity, taking caution not to damage
the cover o-ring during assembly.
