4.2 Clutch Adjustment
In order to ensure the normal operation of the clutch, a
clearance of (2–2.5 mm.) 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 = (10–11 mm.)
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 or disappear. Therefore, inspection and
adjustment should be carried out regularly.
1. The adjustment method for adjusting the path 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+0.2
mm.)
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+0.2 mm.) for 25PS models, and C= (93+0.2
mm.) for 30PS or 35PS models. Tighten the nut (8).
Make sure that the free play of the clutch pedal is (25–30
mm.) 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 35–37 mm. and tighten the lock nut (1).
