Intake manifold

Check flange surface for warpage and correct if necessary. Before
refitting check that heads are in line. Replace gaskets. Tighten nuts
at 2.5 Kgm.

Note

: In case of low temperature starting we can supply a manifold

with provision for a glow plug for air preheating.

Fan control belt

Components:

Guard

Pulley

Spacers

'V'-belt

Loosen the belt guard bolts and the nuts securing the pulley.
Remove 'V'-belt and check for wear. See Page 16 for periodic
maintenance details.

Only check the belt tension when the engine is at a stand still

Belt tension adjustment

Belt tension can be adjusted by adding or removing the spacers
located between the pulleys. Spacers are 0.5, 1.0 and 2.0 mm thick.

Tension check

A 4 Kg. load located halfway between the pulleys should cause the
belt to bend 5÷15 mm.

Shroud and plates

By means of plates

and

the shroud i

sends air to the cylinders

for cooling purposes. Being lined with sound attenuating material it
also reduces the noise generated by the blower fan and cylinders.
