Remove bolts (1) that hold the oil pump to
the scavenge tube.
Bend the locks away from bolts (2) and re-

INSTALL OIL PUMP
1. Turn the crankshaft until the No. 1 piston is
at the top center compression position. See
REMOVE FUEL INJECTION PUMP
HOUSING AND GOVERNOR.
2. Turn both balancer shafts (1) until the flat
part on each shaft is away from the oil pan
plate. Install two 3/8"-16 NC bolts (2) 1
1/2” long through the oil pan plate and into
the holes in the balancer shafts. This will
prevent the shafts from turning. Tighten the
bolts until they are against the bottoms of
the holes in the shafts, then loosen the bolts
1/2 turn.
3. Put oil pump (3) in position on the cylinder
block and install the locks and bolts that
hold the oil pump in place. Connect the
scavenge line to the oil pump. Make sure
there is a new gasket between the oil pump
and the scavenge line.
4. Remove bolts (2). Check to see that the bal-
ancer 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.
