Important
• Check that all components are intact and, if
necessary, replace them with original spares.
• Before replacing the injectors it is always necessary
to replace the flameproof bulkhead, the copper
gasket and the oil and diesel O-ring seals.
• Always make sure that the injectors are calibrated
correctly
(see
"Calibrating and replacing
injector").
1. Insert the flameproof bulkhead (M) in the injector seat,
with the flat part directed as in the drawing.
2. Grease the copper gasket (N) and the oil O-ring seals
(N1) copiously.
3. Install the injector pumps (Q) and fasten the nuts
without tightening them.
4. Tighten the nuts to a temporary torque of 10 Nm.
5. Tighten the nuts to a final torque of 20 Nm.
6. Hook the connecting rod (R) to the adjustment levers
and, fasten the injector pumps without fully
tightening the screws.
7. Tighten the screws to a final torque of 1,1 Nm.
8. Hook the spring (S).
Important
• The following procedures must be performed only if
pumps have been replaced. Otherwise, go directly
to point 13.
Prepare the injector pumps for running the engine, as
explained below.
9. Loosen the screws (T) of every injection pump.
10. Move the plates (U) fully towards the flywheel side
