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;
c) Check the pedal height after the adjustment of pedal free
stroke.

of engine without oscillation.
Remark: Do not disconnect the pipeline of the wheel-brake
cylinder.
12. Tear down the pawl washer and bracket of the rear part
of gearbox:
Two-wheel driving:
(a) Dismantle the four bracket bolts (skip over this process
for the wielding structure).
(b) Lift the engine with jack to raise the gearbox a little.
(c) Dismantle the pawl washer from the rear part of gearbox.
Four-wheel driving:
Dismantle the bolts from the pawl washer and bracket of the
rear part of gearbox to tear down the pawl washer and bracket.
13. Insert the wooden plate between the bottom frame and
the beam.

micrometer.
Max radial run out torlerance

For the transmission made by Shang Chi:0.015mm
For the transmission made by Tang Chi:0.05mm
4. Check the synchronized ring
(a) Turn the ring ,and put it into to check the brake action.
(b) Measure the gap between the rear of the synchronized ring
and gear end.
Standard clearance:
For the transmission made by Shang Chi:(1.5
1.8)mm
For the transmission made by Tang Chi:(1.2
0.4)mm
Limit clearance:0.8mm
5. Measure the clearance between the gear shifting fork
and meshing sleeve
Check the clearance between the gear sleeve and gear shifting
fork with feeler gauge.
Max clearance

For the transmission made by Shang Chi: 0.54mm
For the transmission made by Tang Chi: 0.7mm Transmission

4. Adjust the wheel angle
Take apart the limit bolts of the steering knuckle to check the
steering angle A of inner wheel.

Remark: The wheel should not contact the body or brake hose
when the steering wheel reaches the limit position.
In case the steering angle of inner wheel doesnít conform to the
standard value, adjust the wheel angle through adjusting the
limit bolts of the steering knuckle.

If the wheel angle fails to be adjusted within the standard value,
change the weary or damaged parts of steering system.
If the tilt angle fails to fall within the specified values, make an
adjustment through adding or reducing the gaskets on the
location of upper arm.
Gasket thickness: 3.0, 2.0 and 1.0mm
Once the gasket thickness increases by 1mm, the outer tilt
angle of wheel will change by 7', while the back tilt angle of
kingpin will change 20'.
After the wheel outer tilt angle and the back tilt angle of kingpin
are adjusted, if the inner tilt angle of kingpin still fails to the
specified value, check the steering knuckle or front wheel to
see whether they are bending or loose.
