Test Procedure
1. Remove the screw plug (5) and seal (4) and collect
oil in a suitable vessel.
2. Install the position sensor (1) into the governor
housing of the injection pump to be the guide pin of
the position sensor facing up.
3. Connect the battery terminal of position sensor (1)
to positive terminal (+) of battery.

4. Rotate the crankshaft by hand (in direction of engine
rotation) until the lamp ’B’ lights up. Rotate the
crankshaft carefully further until both lamps ’A and
B’ come on. In this position, check the Rl value on
the crankshaft vibration damper.

Notice
If only lamp ’A’ lights up, repeat the test and if out of
specification, adjust start of delivery.
