7.6.5 Assembling injection-pumps
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 the 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

Prepare the injector pumps for running the
engine, as explained below.
9 - Loosen the screws (T) of every injection
pump.
