Description
The clutch is disengaged by a slave cylinder consisting of a piston (1) housed inside a cylinder mounted to the left-hand crankcase
cover. This piston (1) moves a pushrod (2), which runs through gearbox input shaft and operates the pressure plate (3) located
on top of the clutch plate pack (4).
Motion is transmitted from the clutch centre (5) to the primary shaft through special cush drive rubbers (6), which make for
smoother clutch engagement and thus prevent damage to transmission parts. Before working on the internal clutch parts,
check that the clutch operates correctly. Then deal with the problem in a systematic manner.
The following is a list of possible causes of clutch malfunctions.
A clutch which does not disengage may be caused by:
- excessive play of the control lever;
- distorted clutch plates;
- incorrect spring tension;
- faulty clutch release mechanism;
- excessive wear of the hub or clutch drum.
A clutch which slips may be caused by:
- insufficient play of the control lever;
- worn clutch plates;
- weakened springs;
- faulty clutch release mechanism;
- excessive wear of the hub or clutch drum.
A noisy clutch may be caused by:
- excessive backlash between the primary drive gears;
- damaged primary drive gear teeth;
- excessive play between driving plate tabs and clutch drum;
- worn gear/clutch drum bearings;
- worn cush drive rubbers;
- the presence of metal particles (filings) on the gear teeth.
