Setting Static Fuel Injection Pump
Timing
To set the static fuel injection pump timing, prior
to pump removal, proceed as follows:
1. Remove the TEM sensor (on mechanically
governed engines, remove plug) from the
fixed timing port.
Figure 7-14 — Removing TEM Sensor
Thoroughly clean all residue from the fixed timing
port threads (timing access window) before
installing tool sensor. This will prevent the
possibility of a false reading.
2. Clean all residue from the TEM sensor or
plug threads.
