Adjusting start of delivery
If the check according to method a) or b) should
prove that the delivery start is not correct, proceed
as follows:
Fig. 10
Remove timing case cover (13mm).
Fig. 11
Loosen all bolts fastening the drive gear to the in-
jection pump hub (13mm). For this, two complete
turns of the engine are necessary.

Turn engine to specified angle for delivery start.
Remove cylinder head cover from cylinder no. 6
(flywheel end). When the values of this cylinder
are in crossover, the piston in cylinder no. 1 is at
ignition TDC.
Remove screw plug from governor housing (see
Fig. 5). The delivery start pointer must be visible in
the centre of the inspection hole.
Turn the injection pump camshaft on the drive
flange to the left or right until the conditions men-
tioned under a) or b) apply.
Tighten bolts for fastening drive gear to drive
flange consecutively to 5 Nm and then to 30 Nm.
