d.
Turn crankshaft slowly in the direction of normal rotation and feel for air
being forced out during the compression stroke. When compression is felt
turn crankshaft until timing marks (5) on the FIP (1) are aligned in the
center of the timing hole (6).
The exact pump timing will be indicated by the flywheel degree mark aligned
with the timing pointer.
e .
Aline FIP timing marks (5) exactly and check timing mark on flywheel (7).
Record flywheel degree.
f .
Remove two nuts (8) securing three wires (9) to top of FIP (1). Tag and
remove three wires (9).
Install and hand tighten two nuts (8).
g .
Remove four screws (10), lock washers (11), thrust plate gear hausing cover
(12), and gasket (13) from gear housing (14). Discard lock washers (11) and
gasket (13).
h.
Remove thrust plug (15), spring (16), nut (17), and lock washer (18) that
secure drive gear (19) to FIP drive shaft (20). Discard lock washers (18).
i .
Remove two bolts (21) and lock washers (22) that secure FIP (1) to gear
housing.
Discard lock washers (22).
When the FIP is removed for repair, secure the throttle in the wide open
position after removal. This will prevent internal damage while in transit
or storage.
Place clean rag against drive gear to keep it from falling into gear housing.
j .
Move FIP (1) from gear housing approximately 1/4 inch (6.35 mm).
Using a
mallet, tap FIP drive shaft (20) to remove FIP (1).
3.8.9.2 Repair.
a .
Inspect FIP (1) for damage.
b .
Inspect all mounting hardware for damage.
c .
Replace all damaged or defective components.
3.8.9.3 Installation.
a .
Place thumb over the number 1 cylinder fuel injection nozzle opening on
engine.
b.
Turn crankshaft slowly in the direction of normal rotation and feel for air
being forced out during the compression stroke. When compression is felt,
turn crankshaft until flywheel degree pointer aligns with degree marks as
recorded during removal of FIP. (1).
c .
Remove two bolts (2), cover plate (3), and gasket (4) from side of FIP (1).
