Possible clutch malfunctions, their causes and methods of elimination (VAZ-21011)

Cause	Method of elimination
Incomplete disengagement of the clutch (clutch "leads")
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	Replace the linings or the driven disc assembly
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 grease. If the splines are crushed or worn to the point that they cause seizure, 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 splines are crushed or worn so that it causes jamming, replace the primary shaft or driven disk
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 surface
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	Replace the bearing
Wear of the front bearing of the primary shaft of the gearbox	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 release fork return spring	Replace the clutch housing with pressure plate assembly
