57. Clutch release malfunction (when the pedal is pressed to the floor, it is difficult to engage/disengage reverse gear)
1. The clutch pedal free travel adjustment is incorrect.
2. Oil has gotten onto the clutch driven disc.
3. The diaphragm spring has sagged.
4. There are hydraulic fluid leaks from the clutch master or slave cylinder.
5. Air has entered the clutch drive hydraulic system (there is a soft pedal stroke).
6. The sealing cuff of the piston of the master or slave cylinder is damaged.
7. There is a lack of lubrication in the guide bearing.
58. The clutch is slipping (engine speed increases without increasing vehicle speed)
1. The wheels slip on a slippery surface.
2. The driven clutch disc is overheated - park the car and let the disc cool down.
3. The friction linings of the driven disk are contaminated with oil leaking through the rear crankshaft oil seal.
4. The new slave disk has not been run in (for the final running in of a new disk, at least 30 + 40 starts must be performed).
5. There is deformation of the clutch basket/flywheel assembly.
6. The diaphragm spring is weak.
7. The piston is stuck in the clutch master cylinder due to foreign particles getting in.
8. The clutch release mechanism is jammed.
9. The clutch hydraulic lines are damaged.
59. Vibration occurs when the clutch is engaged
1. The friction linings of the driven disk/working surface of the flywheel are contaminated with oil, deformed, burnt out, or polished to a shine.
2. The rivets securing the friction linings have become loose.
3. The power unit suspension supports are worn out or their fastening has become loose.
4. The splines of the gearbox input shaft or the driven disk hub are worn.
5. There is deformation of the clutch basket/flywheel assembly.
6. There is fatigue deformation of the diaphragm spring.
7. The guide bearing in the crankshaft journal is jammed.
60. When pressing or releasing the clutch pedal, extraneous noises occur
1. The clutch pedal adjustment is incorrect.
2. The release bearing is jammed on the manual transmission shaft.
3. The guide bearing is worn or damaged.
4. The driven clutch disc is cracked.
5. There is fatigue deformation of the torsion springs of the driven clutch disc.
6. Clutch basket assembly components are worn out.
7. The diaphragm spring of the pressure plate is broken.
8. Clutch pedal axle bushings are worn out or dry.
9. The engine idle speed is insufficient.
61. The clutch pedal does not return to its original position after being released
1. The main or slave clutch cylinder is not functioning properly.
2. The piston in the master or slave cylinder is jammed.
3. Clutch release drive components are damaged or jammed.
4. Air has entered the hydraulic system.
62. The clutch pedal requires excessive force to depress
1. The piston in the master or slave cylinder is jammed.
2. The clutch basket assembly is faulty.
3. The master or slave cylinder is installed with the wrong size.
