SERVICE AND MAINTENANCE
The clutch disc wears down as the clutch is used, and this causes the free play of the
clutch pedal to decrease. If you continue to use the clutch with reduced clutch pedal
play, the clutch slips easily. On the other hand, if there is too much free play, the clutch
disengages poorly, making gearshifts difficult.
Inspect whether an abnormal sound is heard or the clutch pedal is abnormally heavy
when the clutch pedal is depressed while the engine is idling. If an abnormal sound is
heard or the clutch pedal operation is heavy with the sufficient air pressure supplied,
provide lubrication. Also, check whether the shift lever can be placed in the 1st or
reverse position easily.

1. Lightly press the clutch pedal by hand
until you feel a slight resistance. The
distance of the pedal movement to
this point is the free play.

2. Make sure that the parking brake
lever is pulled completely. Start and
run the engine at idle and then press
the clutch pedal fully.
3. Move the gearshift lever to the 1st
position and then release the pedal
slowly. The clutch pedal is normal if
the pedal stroke from the fully pressed
position to the position just before the
clutch engages is 60 mm (2.36 in) or
more.
Check also that the clutch engages
smoothly without any slip when the vehicle
starts to move slowly.
