3.3.19. Checking and Adjusting the Timing
In case of difficult starting of the engine, smoky exhaust as well as in case of replacement
and installation of the fuel pump after bench test, every 2,000 service hours or after repair, check
obligatorily the timing on the diesel engine. Check the timing in the following order:
- set the throttle lever to the position corresponding to the maximum fuel delivery;
- disconnect the high-pressure pipe from the first section of the fuel pump and connect
instead the meniscus for setting the timing (momentoscope);
- turn the diesel engine crankshaft clockwise by means of a wrench until the fuel without
air bubbles appears from the glass gauge of the momentoscope;
- remove some quantity of fuel from the glass gauge by shaking it;
- turn the crankshaft back (counter clockwise) by 30-40;
