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 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.
7. 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. 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 “Injection Pump Removal,” p. 79.
NNoottee:: If a different injection pump is being installed, see “Injection Pump Timing,” p. 73 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.
