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.
Position Sensor 617 589 08 21 00
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.

3. Connect the digital tester and TDC pulse sender unit according to connection diagram.
4. Run the engine at idle speed and check the Rl value on the digital tester Notice
If out of standard, adjust the start of delivery.
5. Stop the engine.
6. Remove the Rl sensor, digital tester and TDC pulse sender unit.
7. Replace the seal and tighten the plug.
8. Check engine oil level and adjust if necessary.
