Turn the crankshaft until the No. 1 piston is at
the top center compression position. See IN-
STALL FUEL INJECTION PUMP HOUS-
ING AND GOVERNOR.
Turn both balancer shafts until the flat part on
each shaft is away from the oil pan plate. Install
two 3/8”-16 NC bolts (1) 1½” long through
the oil pan plate and into the holes in the ba-
lancer shafts. This will make the shafts so they
will not turn. Do not tighten the bolts against
the bottom of the holes in the shafts.
Put the oil pump (2) in position on the engine
block and install the locks (left side only) and
bolts that hold the oil pump in place.
Remove bolts (1). Check to see that the ba-
lancer shaft timing is correct. The balancer
shaft timing is correct when the holes in the
balancer shafts are in alignment with the holes
in the oil pan plate, and No. 1 piston is at the top
center compression position.
Connect tube assembly (4) to the oil pump.
Install suction bell (3) and the gasket to the oil
pump.
