Injector for EPA and 97/68 CE engines

The injector is attached to the cylinder head via a forked bracket.
 Tighten the fixing bracket screw at 10 Nm.
 Fix the high-pressure hose union to the injector union at 25 Nm.

Injector projection

The end of nozzle A should project 3.0÷3.5 mm. from the cylinder head
plane.
Adjust injector projection by means of copper shims B measuring 0.5,
1.00 and 1.50 mm in thickness.

CYLINDER HEAD

Important
Do not remove it when hot to avoid deformation.
The cylinder heads must be tightened with the exhaust or intake
manifold mounted to keep them lined up.
lf cylinder head is deformed level it off by removing a maximum of 0.3
mm.
When refitting tighten only if sure that rocker arm lubrication tube is
well inside its holes, and that the rubber seals of the tappet hose are
assembled and inserted correctly into their seats.
Always replace copper head gasket: see page 39 for choosing the right
thickness.
Progressively tighten nuts in the 1, 2, 3, 4 sequence at 55 Nm.
