Crankcase Mark For Adjusting Start Of Fuel Delivery - Hatz 2-4L30 Workshop Manual

1. Crankcase mark for adjusting start
of fuel delivery:
– Insert measuring device - 25 - into the
calibrating device - 26 - and adjust it so
that both needles of the dial gauge are
at „0"; see Fig. 138.
– Insert the measuring device into the
mounting hole on the injection pump
and screw it down firmly. The correct
cam must be on its base circle.
– Turn the flywheel in the normal direction
of engine rotation until the start-of-deli-
very mark on the flywheel (15° before
TDC) for the cylinder in question is alig-
ned with the fixed mark on the crank-
case or in the inspection hole of the
connecting housing; see Fig. 134.
– In this position, take the total dial gauge
reading; see Fig. 139.
– From this total dial gauge reading,
deduct 2.15 ± 0.05 mm and stamp the
remaining value (without +/- sign or
decimal point) into the crankshaft as a
tenths of millimetre value (140/1).
Repeat this procedure for each pump
mounting hole.
