Injection Pump Removal
The injection pump drive gear will not fit through
the gear housing when removing the pump. The
gear must be separated from the pump using tool
P/N 204-1011. When this tool is used, it is not
necessary to remove the water pump belt, fuel
pump, crankshaft pulley, crankshaft seal or front
plate. See Figure 68 “Injection Pump Gear Tool”
on page 104.
1. Note the alignment of the index marks on the
injection pump and the gear case. The index
mark on the injection pump is usually aligned
with the single index mark on the gear case. If
not, mark it so the injection pump can be
returned to the same position when it is
reinstalled.
2. Remove the starter for clearance. Also remove
the fuel lines, harness and mounting hardware
from the injection pump. Cover all injection
lines and fuel lines with plastic covers or tape.
The smallest amount of dirt can damage the
fuel system.
3. Remove the cover plate from the gear case.
Remove the nut and lockwasher that secure
the gear to the injection pump shaft. Use a
shop rag to prevent the lock washer or nut
from falling into the gear case.
NOTE: The injection pump gear assembly is
made of three pieces; the flange, the gear,
and the transfer pump cam. Do not loosen or
remove the four bolts that fasten the gear to
the flange because that changes the timing.
4. Use the hardware from the cover plate to
attach the tool plate (P/N 204-1011) to the
gear case. Attach the plate with the marked
side pointing up and out away from the case.
5. Align the threaded holes in the injection pump
gear with the two holes in the tool plate by
rotating the engine crankshaft. Attach the gear
to the tool plate with the screws provided with
the tool plate.
6. Thread the long screw into the small end of
the adapter (both parts are supplied with the
tool plate). Insert the adapter into the tool
plate. Carefully align the screw over the center
