Inspection and Adjustment of Clutch Pedal, Air Exhausting of Clutch
Air-exhausting of clutch
Remark: in case operation needs to be conducted for the clutch
system or if there is air in clutch, exhaust the air.
Notice : Do not stain the painted surface with brake liquid,
if any brake liquid is left, wash it away immediately.
1.
Fill the brake liquid into the oil cup of clutch master cylinder;
The oil cup of master cylinder shall often be checked and, if
necessary, added with brake liquid.
2.
Connect the ethene resin pipe to the air-exhausting valve.
Insert the other end of the pipe into the container, half of which
is filled with brake liquid.
3. Air-exhausting in clutch system
a) Move the clutch pedal up and down slowly for several times.
b) Loosen the air-exhausting valve when pressing the pedal
increasingly until there is brake liquid overflowing, then
tighten the air-exhausting valve.
c)
Repeat this operation until the bubble in brake liquid disappears.
Inspection on and adjustment
of clutch pedal
1. Check whether the pedal height is correct
Pedal height that begins from front wall board:
Dr SF
(165
5)mm
SL SK SY SJ
(190-200)mm
2. Adjust the pedal height where necessary
Loosen the locking nut and screw off the adjusting bolts until
the pedal height is correct. Then screw up the locking nut.
Pedal free stroke
3. Check whether the pedal free stroke is correct
Press the pedal lightly until the resistance generated by clutch
occurs.
pedal free stroke: (5-15)mm
4. Adjust the pedal free stroke where necessary;
a) Loosen the locking nut and rotate the push-rod until the
stroke is correct;
b) Screw up the locking nuts;

Inspection on clutch parts
1. Check whether there is abrasion or damage of clutch rib;
Measure the depth of the rivet head with calipers.
Min depth of rivet head: 0.3mm
If the depth of rivet head exceeds the limit value, change the
clutch rib.
2. Check the radial pendulum difference of the clutch
Check the radial pendulum difference of the clutch rib with
multi-meter.
Max radial pendulum difference: 0.8mm
If the radial pendulum difference exceeds the max value,
change the clutch rib.
3. measure the rdial pendulum difference of the flywheel;
Check the radial pendulum difference of flywheel with multi-
meter;
Max radial pendulum difference: 0.2mm
If the radial pendulum difference exceeds the max value,
change the flywheel.
4. Check the guide bearing
Exert the force in radial direction to rotate the bearing by hand.
If the guide bearing doesn
t run or if there is great resistance,
change the guide bearing.
Remark: as this bearing is lubricated permanently, it needs not
to be cleaned or lubricated.
5. Change the guide bearing where necessary.
