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.

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.

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.
