Clutch parts
1. Flywheel; 2. Guide bearing; 3. Fork; 4. Bracket; 5. Release bearing; 6. Clutch housing; 7. Friction disc
The clutch is dry, single-disc, diaphragm type, with hydraulic drive.
The hydraulic drive circuit includes the master and slave cylinders in series, through which the force is transmitted from the pedal to the fork and to the clutch release bearing.
The clutch adjustment is carried out automatically.
Clutch wear is indicated by slippage and a characteristic howling sound when engaging a gear. In this case, significant wear of the flywheel and pressure plate is possible.
The wear of the friction disc depends on driving skills, wear is accelerated by frequent use of slippage, or jerky driving due to "throwing" the pedal. The friction disc should be changed approximately after 64,000 km.
It is recommended to perform the following preliminary checks to determine the condition of the clutch.
1. Check the fluid level, restore if necessary (if the tank is empty, add fluid and bleed the hydraulic drive).
2. To check for clutch slippage, press the pedal with the engine idling and after a few seconds engage reverse gear. A grinding noise will indicate increased wear of the pressure or friction discs.
3. Check that the clutch is fully disengaged.
4. To do this, with the engine running, press the clutch pedal so that the pedal is 13 mm from the floor.
5. Shift from 1st gear to reverse several times. Difficulty shifting indicates worn parts.
6. Check the stroke of the working cylinder rod with the pedal fully depressed. If the stroke is small, check the fluid level.
7. Check the condition of the guide bearing, make sure that the clutch fork has no play on the axle.
