Cecking clutch
Check the disk lining for signs of chipping and the disk friction face
for scoring which may prevent the clutch from operating properly.
Check that the sliding surface of the engine flywheel is not scored;
if signs of scoring are evident, machine the surface as indicated
on page 37.
Check the disk thrust plate for scoring or bluish areas caused by
tempering and also ensure the diaphragm-type spring has not lost
its efficiency; if so the whole clutch assembly shall be replaced.
Be sure the clutch disk is free to move in its housing and the friction
lining securing rivets are duly riveted.
Should any wear be found on the thrust bearing or the diaphragm-
type spring, an exhaustive check over the spring operating condi-
tions (installed in the disk thrust lever operating cylinder, see Fig
7) shall be performed; replace if necessary.
On reassembly ascertain dimension A (see Fig 7) between the
operating cylinder fixing face and the push rod contacting the
engagement lever is 180 mm.
NOTE: To facilitate correct clutch disk assembly the use of no.
5.9030.256.4/10 centering tool is recommended.
Warning: with engine running, never ride the clutch pedal with
your foot to prevent the clutch disk from being damaged because
of overheating.
Important: The thrust bearing is prelubricated, and must never on
any account be cleaned with fuel oil or other solvents as these will
render the prelubrication treatment ineffective.
Adjusting clutch control pedal
Make sure the distance between pump fixing surface and fork hole
centre is 187±1 (Fig. 17) otherwise loosen nut A and operate adjusting
stay rod B (Fig. 17).
Bleeding air from the hydraulic circuit
Operate the clutch pedal several times, then keeping the clutch
pedal in fully depressed position, slightly unscrew and soon after
tighten the air bleeding screw valve again (this being located on
thrust lever operating cylinder). This operation should be repeated
as many times as the oil flows out of the bleeding screw valve
without air bubbles.
