Cause | Method of elimination |
| Increased clearances in the clutch release drive | Adjust the clutch release drive |
| Warping of the driven disk (end runout more than 0.5 mm) | Straighten the disk or replace it with a new one |
| Irregularities on the surfaces of the friction linings of the driven disk | Clean the pads with a wire brush or replace them with new ones |
| Loose rivets or broken friction linings of the driven disk | Replace the linings, check the disc end runout |
| Seizure of the driven disk hub on the splines of the gearbox input shaft | Clean the splines, coat with LSC-15 or LITOL-24 grease. If the cause of the jamming is the crushing or wear of the splines, then replace the primary shaft or driven disk |
| Breakage of the plates connecting the thrust flange to the clutch housing | Replace the clutch housing with pressure plate assembly |
| Air in the hydraulic drive system | Pump up the system |
| Fluid leaking from the hydraulic drive system through connections or damaged pipes | Tighten the connections, replace damaged parts, bleed the hydraulic drive system |
| Fluid leak from master cylinder or clutch release cylinder | Replace the sealing rings, bleed the system |
| The hole in the tank cap became clogged, which caused a vacuum in the master cylinder and air to be sucked into the cylinder through the seals | Clean the hole in the tank cap, bleed the system |
| Leakage due to contamination or wear of the front master cylinder seal ring | Clean the sealing ring, replace if worn |
| Loosening the rivets securing the pressure spring | Replace the clutch housing with pressure plate assembly |
| Misalignment or warping of the pressure plate | Replace the clutch housing with pressure plate assembly |
Incomplete clutch engagement (clutch "slips") | |
| There are no gaps in the clutch release drive | Adjust the clutch release 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 oiling of the discs |
| The master cylinder compensation hole is clogged | Flush the cylinder and clean the compensation hole |
| Damage or seizure of the clutch drive | Eliminate the problems that cause sticking |
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 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 release 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 surfaces |
| Loosening of 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 | Clutch release bearing worn, damaged or leaking grease |
| Wear of the front bearing of the primary shaft of the gearbox | Wear of the front bearing of the primary shaft of the gearbox |
Increased noise when engaging the clutch | |
| Damper failure or reduced elasticity of the driven disk | Replace the slave disk assembly |
| Breakage, loss of elasticity or jumping off of the release fork return spring | Replace the spring with a new one or secure it |
| Breakage of the plates connecting the pressure plate to the casing | Replace the clutch housing with pressure plate assembly |
