2. Remove the cover plate from the gear case.
Remove the nut and lock washer which 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.
3. Use the hardware from the cover plate to
attach the tool plate (with the marked side
pointing up and out) to the gear case.
4. 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.
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.
