5. Thread the long screw supplied with the tool plate into
the small end of the adapter, also supplied with the tool
plate. Insert the adapter into the tool plate and rotate to
provide a solid position to force the injection pump
shaft from the gear. Caution should be made to align
the screw over the center of the injection pump shaft.
6. Remove the screw and adapter leaving the tool plate in
place. This holds the gear in proper tooth alignment
until the injection pump is re-installed.
Injection Pump Reinstallation
1. Position injection pump shaft into gear, rotating shaft to
mate key with keyway in gear.
2. Secure injection pump to gear case with previously
removed hardware.
3. Remove hardware holding gear to tool plate, then
remove tool plate.
4. Secure gear to injection pump shaft with lockwasher
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 84 to 90 ft-lb (113 to 122 N•m)
5. Fasten cover plate to gear case and reinstall all compo-
nents removed previously to facilitate injection pump
removal.
Fuel Solenoid System
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 1 amp 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 be
de-energized after a few seconds to keep it from being dam-
aged.
