Cause of defect |
Elimination method |
|
Coupling not completely joins ("slips")
By sharp pressing an accelerator pedal the engine gains steam, but the car almost does not accelerate (it especially noticeable at the movement on rise); the smell of superheated frictional slips can be felt; fuel consumption increases |
The wrong adjustment of the drive of coupling (there is no free wheeling of a pedal) |
Adjust the drive (see. "Coupling", page 98) |
Oiling of a flywheel, press disk, frictional overlays of the conducted disk |
Carefully wash out white spirit or gasoline greasy surfaces and dry wipe them. Replace strongly greasy conducted disk. Remove the cause of oiling (an oil leak through an epiploon of the engine and/or transmission) |
Strong wear or burning of frictional overlays of the conducted disk |
Replace the conducted disk |
Weakening of a diaphragm spring |
Replace a coupling casing |
Jamming of a nave of the conducted disk on vents of a main shaft of the transmission |
Clear vents of dirt, eliminate small damages with a file. At considerable wear or damage of shliyets replace a disk and/or a main shaft of the transmission. Before assembly apply fresh SHRUS-4 lubricant on vents |
The compensation opening of the main cylinder is littered |
Replace the main cylinder |
The piston of the main cylinder slowly comes back to a starting position because of swelling of rubber cuffs |
Replace the cylinder assembled. At suspicion in liquid of a hydraulic actuator of coupling replace it with hit of gasoline or other solvents |
Coupling is not completely switched off ("conducts").
Gear shifting of the forward course is complicated, transfer of a backing joins with noise (see also "Diagnostics of malfunctions of the transmission", page 254) |
The wrong adjustment of the drive of coupling (the full speed of a pedal is small, its free wheeling is increased) |
Adjust the drive (see. "Coupling", page 98) |
Air got to system of a hydraulic actuator (a pedal "soft") |
Pump over system, tighten connections. At leak from the main or working cylinders replace cylinders assembled |
The coupling switching off fork is deformed |
Replace a fork |
Weakening of rivets or breakage of frictional slips, buckling of the conducted disk (a face beating more than 0,5 mm) |
Replace a disk |
Strong and uneven wear, teases on working surfaces of a flywheel or a press disk |
Pierce or replace a flywheel. At damage of a surface of a press disk replace a coupling casing |
Distortion or buckling of a press disk |
Replace a casing with a press disk in collecting (coupling "basket") |
Jamming of a nave of the conducted disk on vents of a main shaft of the transmission |
Clear vents of dirt, eliminate small damages with a file. At considerable wear or damage of shliyets replace a disk and/or a main shaft of the transmission. Before assembly apply fresh SHRUS-4 lubricant on vents |
Weakening of rivets of connecting plates of a casing of coupling or diaphragm spring, breakage of plates |
Replace a coupling casing |
The coupling switching off bearing is jammed |
Replace the bearing |
Coupling is not switched off (the pedal "fails") |
The coupling switching off fork is strongly deformed or broken |
Replace a fork |
Availability of air in system of a hydraulic actuator |
Pump over system, tighten connections. At leak from the main or working cylinders replace cylinders assembled |
Coupling is not switched off (the pedal "fails"). It is short-term it is possible to switch off coupling only sharp pressing a pedal |
Strong wear, defects of a mirror of the main cylinder; dirt in the cylinder |
Clean or replace the cylinder |
Malfunction of cuffs of the main cylinder |
Replace the cylinder assembled |
Breakthroughs at start-off |
Jamming of a nave of the conducted disk on vents of a main shaft of the transmission |
Clear vents of dirt, eliminate small damages with a file. At considerable wear or damage of shliyets replace a disk and/or a main shaft of the transmission. Before assembly apply fresh SHRUS-4 lubricant on vents |
Deformation of the conducted disk |
Replace the conducted disk |
Weakening of fastening of frictional overlays of the conducted disk, strong wear or cracks on slips |
Replace the conducted disk |
Loss of elasticity of spring plates of the conducted disk |
Replace the conducted disk |
Considerable draft or breakage of springs of a quencher of tortional fluctuations, wear of windows under springs |
Replace the conducted disk |
Teases on working surfaces of a flywheel or a press disk |
Replace a flywheel or a casing of coupling |
Jingle, knock or noise at coupling inclusion |
Considerable draft or breakage of springs of a quencher of tortional fluctuations, wear of windows under springs |
Replace the conducted disk |
Deformation of the conducted disk |
Replace the conducted disk |
Weakening of fastening of frictional overlays of the conducted disk, strong wear or cracks on slips |
Replace the conducted disk |
Uniform noise at the switched-off coupling |
Wear of the bearing of switching off of coupling or absence of lubricant in it |
Replace the bearing |
Wear of the forward bearing of a main shaft of the transmission (in an end face of a bent shaft) or absence of lubricant in it |
Replace the bearing |
Coupling pedal scratch |
Plastic plugs of a pedal are not greased |
Grease Litolom-24 or SHRUS-4 plugs |
Plastic plugs of a pedal are strongly worn-out |
Replace plugs, before installation grease them with Litolom-24 or SHRUS-4 |
After a coupling pedal otpuskaniye it does not come back to a starting position |
Availability of air in system of a hydraulic actuator |
Pump over system, tighten connections |
Lost elasticity or the returnable spring of a pedal and/or a clutch release fork lever is broken |
Replace a spring (springs) |
