- while rotating slowly the diesel engine crankshaft clockwise, observe the fuel level in
the tube; at the moment when the fuel will rise, stop the crankshaft rotation;
- turn out the splint from the threaded hole of the rear sheet in accordance with Fig. 27
and insert it in the same hole with its opposite side directed towards until it rests
against the flywheel; when doing this, the splint shall be aligned with the hole in the
flywheel.
This means that the first cylinder piston is set to the position corresponding to:
- 20 before the top dead centre for the D-243 diesel engine and its modification, D-245
and D-245.2;
- 18 before the top dead centre for the D-245.4 and D-245.5 diesel engines.
If the timing is wrong, splint and flywheel hole do not align, adjust it as follows:
remove the cover (fig.28);
align the splint with the drilling in the flywheel by rotating the crankshaft;
loosen fuel pump drive nuts (make 1-1 ½ turns);
