Clutch Adjustment

In order to ensure the normal operation of the clutch, a
clearance of (2–2.5mm) should be kept between the end
of disengaging lever 4 of the main clutch and the surface
of release bearing 5; a clearance of B = (10–11mm)
should be kept between the end of disengaging lever 6
of the auxiliary clutch and the surface of release bearing
5. During use, because of the continuous abrasion of the
clutch friction plates, the clearance mentioned above
will gradually narrow
inspection and adjustment should be carried out
regularly.
1. The adjustment method for adjusting the play of the
clutch pedal is as follows:
First loosen the lock nut (3) on the adjustment screw (2)
(see Figure 4-1), Rotate the adjustment screw (2).
Adjust the distance between the working surface of the
three main clutch disengaging levers (4) and the clutch
pressure plate (1), make the distance A=(86.5+0.2mm)
for 25PS models, and A=(91.5+0.2mm) for 30PS or
35PS models. Tighten the lock nut (3). Loosen the nuts
(7 and 8), and rotate the adjustment screw (8). Make the
distance between the working surfaces of the auxiliary
clutch disengaging lever (6) and the clutch pressure
plate (1) to be C=(78.5+0.2mm) for 25PS models, and
C=(93+0.2mm) for 30PS or 35PS models. Tighten the
nut (8). Make sure that the free play of the clutch pedal
is (25–30mm) by adjusting the clutch rod front fork (4)
(see Figure 4-2), and tighten the nut (5) after the
adjustment (see Figure 4-2).
2. The adjustment method for the throw of the clutch
pedal is as follows:
Loosen the lock nut (1) (See Fig. 4-2) and rotate the
limit screw (2). Make the throw under the clutch rocker
arm (3) to be 35–37mm and tighten the lock nut (1).
