Coupling

Cause of defect

Elimination method

Coupling revolves (not completely joins) By sharp pressing a "gas" pedal the engine grows, but the car is not dispersed almost (it especially appreciable at movement on lifting); the smell of the burned slightly frictional slips can be felt; fuel consumption increases
Zamaslivaniye of a flywheel, a press disk, frictional overlays of a conducted disk Eliminate the zamaslivaniye reason (an oil leak through engine or transmission cuffs). Carefully wash out solvent or gasoline greasy surfaces and dry wipe them. Strongly greasy conducted disk replace

Wear or burning of frictional overlays of a conducted disk

Replace a conducted disk

Decrease in effort of a diafragmenny spring

Replace a coupling casing

The piston of the main cylinder slowly comes back to a starting position because of swelling of a cuff or a contamination of a compensatory opening

Replace cuffs or the cylinder assembled. Clean a compensatory opening. Replace brake liquid

Coupling "conducts" (is not completely switched off) gear shifting Is complicated. The transmission is serviceable

The wrong adjustment of a drive of coupling (the full speed of a pedal is small)

Adjust a drive. Replace a coupling fork if it is deformed

Air got to system of a hydraulic actuator

Pump over system, tighten connections

Weakening of rivets or breakage of frictional slips, buckling of a conducted disk (face palpation more than 0,5 mm)

Replace a conducted disk

Non-uniform wear, teases on working surfaces of a flywheel or a press disk

Pierce or replace a flywheel (with the subsequent balancing). At damage of a surface of a press disk replace a coupling casing

Jamming of a nave of a conducted disk on shlitsa of primary shaft of a transmission

Clear shlitsa of dirt and corrosion, small damages eliminate with a file. At considerable wear or damage of shliyets replace a disk and/or primary shaft of a transmission. Before assembly put on a shlitsa CV JOINT-4 greasing

The bearing is jammed vyzhimny

Replace the bearing

Distortion or buckling of a press disk

Replace a coupling casing assembled

Petals of a diafragmenny spring do not lie in one plane

The vystupaniye of separate petals on size no more than 0,25 mm is allowed. Turn in petals or replace a coupling casing

Wear of petals of a diafragmenny spring in a place of contact to the vyzhimny bearing

Replace a coupling casing

Coupling is not switched off (a pedal "fails")

The fork of switching off of coupling is deformed or broken

Replace a fork

Air in hydraulic actuator system

Pump over system, tighten connections

Coupling is not switched off (a pedal "fails"). Quickly to switch off coupling it is possible in only sharp pressing a pedal

Wear, defects of a mirror of the main cylinder; dirt in the cylinder

Wash out or replace the cylinder. When dismantling the cylinder replace cuffs

Wear or defect of cuffs

Replace cuffs or the cylinder assembled

Breakthroughs at a troganiye

Jamming of a nave of a conducted disk on shlitsa of primary shaft of a transmission

Clear shlitsa of dirt and corrosion, small damages eliminate with a file. At considerable wear or damage of shliyets replace a disk and/or primary shaft of a transmission. Before assembly put on a shlitsa CV JOINT-4 greasing

Deformation of a conducted disk

Replace a conducted disk

Weakening of fastening of frictional overlays of a conducted disk, wear or cracks on slips

Replace a conducted disk

Loss of elasticity of spring plates of a conducted disk

Replace a conducted disk

Considerable a deposit or breakage of springs of a quencher of krutilny fluctuations, wear of windows under springs

Replace a conducted disk

Petals of a diafragmenny spring do not lie in one plane

The vystupaniye of separate petals on size no more than 0,25 mm is allowed. Turn in petals or replace a coupling casing

Teases on working surfaces of a flywheel or a press disk

Replace a flywheel (with the subsequent balancing) or a coupling casing

Zamaslivaniye of working surfaces of frictional overlays of a conducted disk

Eliminate the zamaslivaniye reason (an oil leak through engine or transmission cuffs).
Carefully wash out White-spiritom or gasoline greasy surfaces and dry wipe them.
Strongly greasy conducted disk replace

Jingle, knock or noise at coupling inclusion

Considerable a deposit or breakage of springs of a quencher of krutilny fluctuations, wear of windows under springs

Replace a conducted disk

Deformation of a conducted disk

Replace a conducted disk

Weakening of fastening of frictional overlays of a conducted disk, wear or cracks on slips

Replace a conducted disk

Uniform noise at the included coupling or at its switching off

Wear, damage of the vyzhimny bearing of coupling or lack of greasing in it

Replace the bearing

Scratch of a pedal of coupling

Plastic plugs are not greased

Grease plugs with any greasing

Plastic plugs of a pedal are worn-out

Replace plugs, before installation grease them with any greasing

After an otpuskaniye of a pedal of coupling it does not come back to a starting position

Lost elasticity or the returnable spring of a pedal is broken

Replace a spring
