100 cc 75 cc
Note: Intermediate production 75 cc and 100 cc pumps
use the same charge pump drive shaft. Two
keyways are provided in the drive shaft for the
charge pumps used in these units. The rear
keyway (with identifier groove) is used in 75 cc
pumps. The front keyway (closest to the inter-
nally splined end of the shaft) is used in 100 cc
pumps.
8. Install the charge pump shaft. The internally splined
end of the shaft must engage the main pump shaft.
Note: The outside diameter of the internally splined
end of some early production charge pump
shafts was chamfered. Early production end
caps may not be machined to accept a non-
chamfered shaft. Always use a chamfered
charge pump shaft in pumps with the early end
cap.
9. For pumps with an auxiliary mounting pad, install the
auxiliary drive coupling.
10. Install a new O-ring onto the non-auxiliary pad charge
pump cover. (If an auxiliary pad is installed, an O-ring
is not used on the cover.)
11. Carefully remove the alignment pin from the charge
pump parts. Install the pin in its hole in the charge
pump cover (see previous page for correct orienta-
tion) and retain with petroleum jelly. Install the cover
(with alignment pin) into the end cap and aligned
charge pump parts. (Take care not to damage the
cover O-ring, if used.)
Caution
In order to avoid loss of charge pressure in pumps
with an auxiliary mounting pad, always install the
charge pump cover with the pad drain hole located
on the same side of the end cap as the charge inlet
port. Refer to the section „Auxiliary Pad Installation“
for details.
