Installing the Pump
Verify Cylinder Number 1 is at TDC by barring engine
slowly while pushing in on TDC pin.
Install a new gasket.
Note: The shaft of a new or reconditioned pump is
locked so the key aligns with the drive gear keyway
when Cylinder Number 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.
