CHECKING INJECTION TIMING (BEGIN OF DELIVERY) WITH DIGITAL TESTER (RIV METHOD)

Testing and adjusting value
RI-test value (indirect injection timing) -15° ± 1.5° (after TDC)
RI-adjusting value (indirect injection timing) -15° (after TDC)

Tightening torque
Closing plug on regulator (measuring point) 30-35 Nm (22-26 ft lb)

Special tools

RI-transmitter (617 589 10 21 00):

RI-adapter (for available digital testers) (617 589 09 21 00):

Digital tester e.g. Bosch, MOT 001.03









Testing




1. Connect tester according to wiring diagram.

2. Remove closing plug (2) on regulator housing, screw in RI-transmitter (5) and connect electrically with tester.




Attention! When removing closing plug, approx. 0.2 l of engine oil will flow out. Collect oil.

3. Start engine. Read RI-value (indirect injection timing) and idle speed 700-800 rpm on tester.

RI-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). With Digital Tester (RIV Method)

4. Stop engine.

5. Disconnect tester, remove RI-transmitter and screw in closing plug.

6. Run engine and check for leaks.

7. Check oil level and correct, if required.
