Injection Pump Reinstallation
1. Position injection pump shaft into gear, rotating shaft to mate key with keyway in gear. Take
care to make sure the key mates with the keyway.
2. Secure injection pump to gear case with previously removed hardware. Make sure to align
the index marks on the injection pump and the gear case like they were in step 1 of

e:: If a different injection pump is being installed, see
“Injection Pump Timing,” p. 59
to
set the timing.
3. Remove hardware holding gear to tool plate, then remove tool plate.
4. Secure the gear to the injection pump shaft with the lock washer and nut. Use a shop rag, as
before, to prevent the lock washer or nut from falling into the gear case. Torque the nut to 78
to 88 N•m (58 to 65 ft-lb).
5. Fasten cover plate to gear case and reinstall all components removed previously to facilitate
injection pump removal.
Fuel Solenoid
The fuel solenoid is located on the end of the injection pump. It contains two coils: the pull-in
coil, and the hold-in coil. The pull-in coil draws approximately 35 to 45 amps at 12 volts. The
hold-in coil draws approximately 0.5 amps at 12 volts.
The pull-in coil must be energized to move the injection pump governor linkage to the fuel on
position. Once the injection pump governor linkage has been moved to the fuel on position, the
hold-in coil will keep it in fuel on position until the 8D circuit is de-energized. The pull-in coil must
