the engine back (against direction of rotation) approx-
imately 30° (41/42/43/44/300 series) and approxi-
mately 45° (31/32 series) or until the clock "stops".

Turn the engine in the direction of rotation. Ensure
that the clock does not move when the rotation be-
gins, this is to ensure that the turning begins at
"zero".

cator should be read off. Compare the read off value
with Workshop manual "Technical data".

If the injectors need to be adjusted, slacken off the
pump securing nuts and turn the pump until the cor-
rect value is obtained. Turn clockwise (seen from the
front) if value is too low (injection too late) and coun-
ter-clockwise if the value is too high (injection too
early).
Tighten the pump and dismantle specialtools. Rein-
stall the reset cover (144P-A series only).
NOTE! The support bracket at the rear of the pump
must block the cylinder block and pump before final
tightening, so that no tensions are introduced.
NOTE! Do not forget to remove tool 884 895 from the
flywheel housing.

ets underneath and at the rear are installed. Wrench
