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 Figure 22, p. 73).
