| Cause of malfunction | Method of elimination |
| Incomplete disengagement of the clutch (clutch "leads") | |
|
Reduced full travel of clutch pedal |
Repair the clutch release drive |
| Warpage of the driven disk (end runout more than 0.5 mm) | Replace the slave disk assembly |
| Unevenness on friction surfaces driven disk linings | Same |
| Loose rivets or broken friction driven disk linings | Same |
| Driven disk hub jamming on splines primary shaft of the gearbox | Clean the splines, coat with LSC-15 grease. If the reason for the jamming is the crushing or wear of the splines, then replace primary shaft or driven disk |

| Incomplete clutch engagement (clutch "slips") | |
|
Increased wear or burning of the friction linings of the driven disk |
Replace the slave disk assembly |

| Jerks when engaging the clutch | |
|
The driven disk hub is jammed on the splines of the primary shaft |
Clean the splines, lubricate with LSC-15 grease. If the cause of jamming is the crushing or wear of the splines, then if necessary, replace the input shaft or driven disk |
| Oiling of the friction linings of the driven gear disk, flywheel surfaces and pressure plate | Wash oily parts thoroughly with white spirit surfaces and eliminate the cause of oily discs |
| Jamming in the shut-off drive mechanism clutches | Replace the deformed parts. Eliminate reasons causing seizure |
| Increased wear of the friction linings of the driven gear disk | Replace the slave disk assembly |
| Loosening of friction lining rivets slave disk | Same |
| Surface damage or warping pressure plate | Replace the clutch housing with pressure plate in collection |
| Increased noise when disengaging the clutch | |
| Wear, damage or leakage of lubricant from clutch release bearing | Replace the bearing |
| Increased noise when engaging the clutch | |
| Breakage of the plates connecting the pressure milker with with a casing | Replace the clutch housing with pressure plate in collection |
