Marking The Crankcase For The Radial Position Of The Injection Pumps; Adjusting Injection Volume For Nominal Power Output (Engine Stopped) - Hatz 2-4L30 Workshop Manual

2. Marking the crankcase for the radial
position of the injection pumps:
– Insert the locating pin - 27 - into the
hollow-drilled stud bolt of pump 1 to
lock the governor rod in position „X"
(141/1).
– Insert the marking device - 23 - into the
injection pump mounting hole, turn
clockwise to make proper contact and
stamp the mark on the crankcase; see
Fig. 142.
Make this mark for each injection pump
mounting hole.
3. Adjusting injection volume for
nominal power output
(engine stopped)
– Move the speed control lever to the
„Stop" position.
– Remove the screw plug from the moni-
toring block housing or replace the val-
ve solenoid by the plate of the adjusting
tool -28-, then use a depth gauge to
measure the distance „S" from the outer
edge to the flat face on the piston insi-
de; see Fig. 143.
– Screw in the injection volume adjusting
tool - 28 -, using a number of cooper
sealing rings according to the following
table:
S (mm) Number of sealing rings
≤ 11,3
≥ 11,3
