Cylinder height adjustement

Between the top face of the cylinder and the piston at top dead cen-
ter, there must be a clearance of:
In order to carry out this operation correctly, make the
check with the cylinder pressed well down on its crankcase
(fig. 72).
The clearance is adjusted by means of shims inserted between the
lower face of the cylinder and crankcase (fig. 73).
Shim dimensions: 0.1 to 0.2 mm

Checking valve head face depth

When replacing valves check that the clearance from the top of the
head to the face (fig. 74) is of:
Fitting mm
0,9 ÷ 1,1
For different values see on pages 18-19.

Before mounting the heads on the cylinders, insert injectors in their
housings and after having secured them temporarily, check protusion
of nozzles from head surface (fig. 75).
Protusion S should be:
