7. Loosen the screw (1) blocking rotation of the
pump spindle and insert the
8. Tighten the screw (1), locking part (2) so that the
spindle of the fuel pump can turn freely.
9. Remove the plug on the pump cover.
10. Fit the dial gauge 380000228 (2) and the associ-
ated tool 380000914 (1), pre--loading the shaft
by 2.5 mm (0.0984 in).
11. Unhook the pin (4, fig. 215) of tool 380000988,
turn the engine flywheel and move away from the
condition of the 1° cylinder at T.D.C.
12. This operation makes it possible to use the dial
gauge (2) to check that the pumping device in the
pump moves to the bottom limit equivalent to the
lowest indication of the dial gauge pointer.
13. In these conditions, reset the dial gauge and turn
the crankshaft in the opposite direction to go
back into the condition of the 1° cylinder at the
TDC in the phase of the end of compression.
In this position the dial gauge on the pump must
read off a value of 1 mm (0.0393 in).
14. Turn the pump anticlockwise if the stroke is any
less, or clockwise if the stroke is any greater in or-
der to obtain the prescribed stroke.
15. Verifying these conditions, lock the pump by
tightening the nuts to the torque shown on
page 12.
16. Fit the priming pump (1) on the crankcase (3) and
tighten the retaining bolts (2) to the prescribed
torque.
17. Remove the tools 380000988 and 380000732
for retaining/rotating the flywheel and place the
starter motor in its seat.
