Proceed as follows (Fig. 12):
1. Remove the electric stop and put the accelerator
at maximum speed.
2. Close plunger outlets 2, 3, 4, 5, 6.
3. Position the throttle control lever on minimum
(1/4 of its travel).
4. Connect hand pump 17 (Ref. IVECO 99365034)
to the injection pump inlet port and close the
pump outlet port.
5. Bleed the system.
6. Position the flywheel so as to align the 8° or 19°
mark (item 10 -- Fig. 8) with indicator 11.
7. Remove cap 19 (Fig. 9) and check that plunger
N° 1 is in the initial delivery position, i.e. lower
position.
8. Alternatively, check whether the valves of the
N° 1 cylinder are closed. N° 6 cylinder valves will
be balanced. If they are not, turn the engine
crankshaft one full turn.
9. Turn the engine crankshaft clockwise about half
a turn while looking at the flywheel.
10. Operate hand pump 17 while at the same time
turning the engine crankshaft counterclockwise.
NOTE: This procedure must be carried out slowly but
steadily, with no interruptions.
11. Stop the crankshaft rotation as soon as fuel stops
flowing from the N° 1 plunger connector.
12. Check that the 8° or 19° mark (item 10 -- Fig. 8)
is aligned with indicator 11. If necessary, change
position of cam 16 (Fig. 10 -- 375 and 450 hp) or
plate 17 (Fig. 11 -- 300 hp).
13. Complete the procedure as described above
under item 9 on previous page.
