See that
PC
mark on flywheel aligns with timing
pointer on gear case cover, Figure 27.

Align
PC
mark on flywheel to timing pointer by
rotating crankshaft clockwise in the direction of
engine rotation to take out all gear backlash
in
that direction.
INSTALLING PUMP
Another method of aligning the drive gear slot for
pump installation uses a straight edge as shown. An
experienced person can “eye ball” the slot in the
screw hole and place the pump on the engine with
proper gear teeth meshing.
.-
The flat area just above the pump has a number markedonit which
refers to the shim thickness required between the pump and its
’
mounting pad
for
assuring proper backlash in the gearing. Don’t
forget the
shims.
With the pump drive gear locked by the 1/8-inch
(3.18 mm) brass rod, position the pump in the hole
(Figure 29) and firmly apply pressure. The arr0.w on
Figure 29 shows the position of the injection pump
cam and gear on the camshaft. A slight spring
reaction indicates the pump and camshaft gears are
meshed. Maintain this pressure, remove brass rod
and rotate the crankshaft manually to make sure the
gears mesh properly, Figure
30.
Install mounting
screws and torque to 15-16 ft. Ib. (20-22 Nom).

Remove the screw shown on the side of the pump,
rotate drive gear, and insert
a
