Testing
om617 - 0244-1.jpg
1   Connect tester according to wiring diagram.
2   Remove closing plug (2) on regulator housing, screw in Rl-transmitter (5) and connect electrically with tester.

 

Attention!
When removing closing plug, approx. 0.2 I of engine oil will flow out. Collect oil.
3 Start engine. Read Rl-value (indirect injection timing) and idle speed 700—800/min on tester.
om617 - 0244-2.jpg
Rl-test value: -15° ± 1° (after TDC)
Note: If tester indicates values such as: on Bosch MOT 001.03 -20° or +147° or
-151
Hartmann & Braun +67° or -89°, the injection pump is more than 5° too much in retard.

 

For adjustment refer to adjusting injection timing (begin of delivery) (07.1-114).
4   Stop engine.
5   Disconnect tester, remove Rl-transmitter and screw in closing plug.
6   Run engine and check for leaks.
7   Check oil level and correct, if required.
