| Cause of malfunction | Method of elimination |
| Incomplete disengagement of the clutch (clutch "leads*") | |
| Reduced full travel of clutch pedal | Adjust the clutch drive |
| Warpage of the driven disk (end runout more than 0.5 mm) | Straighten the disc or suede it with a new one |
| Irregularities on the surfaces of the friction linings of the driven disk | Replace the linings or the driven disc assembly |
| Loose rivets or broken friction linings of the driven disk | Replace the linings, check the disc axial runout |
| Seizure of the driven disk hub on the splines of the gearbox input shaft | Clean the splines, coat with LSC-15 grease. If the cause of the jamming is the crushing or wear of the splines, then replace the primary shaft or driven disk |
| Air in the hydraulic drive system | Pump up the system |
| Fluid leaking from the hydraulic system through connections or damaged lines Fluid leaking from the master cylinder or slave cylinder of the clutch drive | Tighten the connections, replace damaged parts. Bleed the hydraulic drive system. Replace the master or slave cylinder |
| Loosening the rivets securing the pressure spring | Replace the clutch housing with pressure plate assembly |
| Misalignment or warping of the pressure plate | Same |
| Incomplete clutch engagement (clutch slips) | |
| No free play in the clutch pedal | Adjust the clutch drive |
| Increased wear or burning of the friction linings of the driven disk | Replace the friction linings or the driven disc assembly |
| Oiling of the friction linings of the driven disk, flywheel surfaces and pressure plate | Thoroughly wash the oily surfaces with white spirit, eliminate the causes of oily discs |
| Damage or seizure of the clutch drive | Troubleshoot the problem causing the jamming |
| 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 the jamming is the crushing or wear of the splines, then replace the primary shaft or driven disk if necessary |
| Oiling of the friction linings of the driven disk, flywheel surfaces and pressure plate | Thoroughly wash the oily surfaces with white spirit and eliminate the cause of the oily discs |
| Clutch drive mechanism jamming | Replace deformed parts. Eliminate the causes of jamming |
| Increased wear of the friction linings of the driven disk | Replace the pads with new ones, check for damage to the disc surface |
| Loosening the rivets of the friction linings of the driven disk | Replace faulty rivets and, if necessary, linings |
| Damage to the surface or warping of the pressure plate | Replace the clutch housing with pressure plate assembly |
| Increased noise when disengaging the clutch | |
| Clutch release bearing worn, damaged or leaking grease | Replace the bearing |
| Increased noise when engaging the clutch | |
| Breakdown or loss of elasticity of the driven disk damper springs | Replace the slave disk assembly |
| Breakage, loss of elasticity or jumping off of the clutch release fork retaining spring | Replace the clutch release fork |
| Breakage of the plates connecting the pressure plate to the casing | Replace the clutch housing with pressure plate assembly |
