DISASSEMBLY/REASSEMBLY
SPEED GOVERNOR
Fit the governor gear on the pin attached to the timing cover and lock it
in position with the circlip, then fit the cap and the counter weight. The
two counter weights are fixed to the governor gear by means of two
holed rivets; these rivets must be replaced in case of disassembling of
the counterweights or gear (fig.35a). Remember to hammer the riv-
ets after fitting the gear mechanism or the counterweights. Insert the
inside lever of the governor into the block and lock in position with
the two circlips (fig.35b).
TIMING COVER
After having fitted the governor unit, as shown in paragraph 7.3, proceed as
follows:
a) fit the protective bushing code 1460.106 on page 42 to the conical end
of the crankshaft.
b) fit the timing cover, remembering to position the gasket between the two
surfaces (fig. 36) and torque the screws to a 23.5 Nm value.
N.B.: care should be taken when mating the governor gear with the
crankshaft gear. Do not force the cover if the mating has not been
carried out correctly, as this action may result in serious damage
to the governor gear.
TIMING PULLEY ASSEMBLY
Pre-heat the pulley to 150 - 180° C for a few minutes, position the key in
it seat on the drive shaft, insert the pulley with its flat surface pointing
towards the engine housing so that the timing point is visible.
Use tool code 1460.112 on page 42 (fig. 37) to position the pulley.
CYLINDER HEAD ASSEMBLY
Insert the head gasket (fig. 38a) between the head and the cylinder.
Tighten the screws alternatively from opposite sides, following the
diagram in fig. 38b.
Use a torque wrench to tighten the screws to a 39.2 Nm - 4 Kgm
torque value.
