9.6.2 Injection pump
Important
•
Always change screws T with new ones or
alternatively apply Loctite 270 (Fig. 9.34) to the
threads.
1. Perform the operations described in the warning in
Par. 6.1.5.
2. Place a dial gauge to detect the TDC on piston N° 1,
then bring the indicator of the dial gauge to 0.
NOTE: During the detection phase of the TDC, check that
cylinder N° 1 is in compression phase (align the notches W
as in Fig. 9.33).
3. By means of the identified pump code, refer to Tab.
6.1 to know the advance degrees and the
corresponding value to lower the piston.
4. Mount tool
ST_34
(Fig. 9.29) and fix it with two motor fixing screws.
5. Having identified the value to lower the piston,
rotate the crankshaft anti-clockwise by going
beyond the value described in Tab. 6.1, once again,
rotate the crankshaft clockwise stopping at the
correct advance value by using tool
6. Lock the ST_34, ensure that the crankshaft does
not rotate, which would alter the correct advance
value.
If this happens, repeat the instructions described in
points 4, 5 and 6.
