Injection Pump Timing
Use this timing procedure when installing a new
injection pump. It is not necessary to use this timing
procedure when removing and reinstalling the original
injection pump. In that case, align the index marks on
the injection pump and the gear case as they were
before removing the injection pump.
1. Before removing the old injection pump, 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 index mark on the
gear case. If not, make a mark on gear case in line
with the index mark on the injection pump (see
).

2. Clean the area with brake cleaner or something
similar. Place an injection angle sticker on the gear
case so the center line on the sticker is aligned with
the index mark on the injection pump. An injection
angle sticker is provided with the new injection
pump.
