Setting start of delivery
If the start of delivery as determined in the
checks carried out in accordance with
method a) or b) is not correct, proceed as
follows:
Remove cover above the injection pump
drive gear.
Losen the fixing bolts joining the drive
gear to the injection pump hub. For this a
full revolution of the engine will be re-
quired.
Set the engine so that the cylinder no. 1 is
at the specified number of degrees before
firing top dead centre (TDC).
Remove screw plug on governor housing.
The pointer for start of delivery must be
visible in the centre of the inspection hole.
Turn the injection pump camshaft to the
left or right as necessary until the condi-
tions required for a) or b) (depending on
which method is being used) are ob-
tained.
Tighten mounting bolts on drive gear in
turn, at first with 10 Nm, then with
30 Nm.
Check start of delivery again.
Close up governor housing.
