Install (005-014-026)
Verify cylinder No. 1 is at TDC by barring engine slowly
while pushing in on TDC pin.
Install a new gasket.
CAUTION
The driveshaft must be clean and free of all oil before
installation. Failure to make certain the driveshaft is
free of oil can result in the drive gear slipping on the
shaft.
NOTE: The shaft of a new or reconditioned pump is locked
so the key aligns with the drive gear keyway when cylinder
No. 1 is at TDC on the compression stroke.
Install the pump. Make sure the key does not fall into the
gear housing.
Use your hands to tighten the three mounting nuts. The
pump must be free to move in the slots.
