Dismantling the clutch shock absorber. With the clutch removed, take
out the three countersunk screws, prise out the cover plate 043187.
Use an old gear box mainshaft held in a vice and put the clutch body
on the shaft. Use the tool shown in Fig. 14 then compress the large
rubbers, by leverage, use a pointed spoke to pick out the thin rubbers.
The thick ones will come out without difficulty.
Use the same method if the gear box is still in the frame, with top gear
engaged and pressure on the brake pedal. Very firmly tighten the plate
screws and centre pop between the screw head and the plate.
Assembling the clutch. After replacing the rubbers, make sure that the
three screws are well tightened, then centre pop the screws for security
as these screws are prone to come loose.
