GENERAL INFORMATION

REASON
WAY OF ELIMINATION
Coupling twitches
Too low frequency of rotation of a shaft of the engine in an idling mode Check system of regulation of frequency of rotation of a shaft of the engine in an idling mode.
The bearing of a shaft of the engine and the bearing of a shaft of a transmission are faulty Check, if necessary replace.
Non-uniformly the disk adjoins press Replace press a disk.
Not firm disk of coupling Establish a firm disk of coupling.
Coupling slips
The coupling disk wore out Check thickness of a disk of coupling, if necessary replace a coupling disk.
The restrictive emphasis of a pedal of coupling is faulty Check a restrictive emphasis of a pedal of coupling.
Too low tension of a tarelchaty spring Replace press a disk.
Jams the distributive cylinder Replace the distributive cylinder.
The distributive cylinder is not tight Carry out visual control.
The frictional slip hardened and was made oily Replace a coupling disk, eliminate the pollution reason.
Coupling was перегрето Establish firm details.
Coupling is incorrectly separated
The sensor cylinder is not tight Check the sensor cylinder, charge to squeeze out a pedal and check, whether liquid in a receiver began to boil.
Air in coupling system Remove air from a drive of management with coupling.
The pedal of coupling does not reach a restrictive emphasis Check a restrictive emphasis of a pedal of coupling, if necessary cut out a rug.
Zalipayet a frictional slip because of an istiraniye Replace a coupling disk.
The disk of coupling jams on primary transmissions, melkoshlitsevy connection dried or залипает Clear melkoshlitsevy connection, remove agnails, if necessary remove a rust.
The disk of coupling has lateral palpation Charge to check a coupling disk, if necessary replace.
The aligning bearing of primary shaft of a transmission on cranked to a shaft is faulty Replace aligning bearing on cranked to a shaft.
Inconvenient rotation of the bearing of the coupling of switching off of coupling or heavy course of a pedal Replace the bearing of the coupling of switching off of coupling, the pedal should be squeezed out easily.
The pedal of coupling does not come back back or comes back with delay
Air in coupling system Remove air from a drive of management with coupling.
Old (oxidized) brake liquid Replace brake liquid.
Jams the distributive cylinder or the cylinder sensor Replace the distributive cylinder or the cylinder sensor.
The coupling disk is worn-out Replace a coupling disk.
Because of an overheat the coupling disk in view of what weakened effort of its reset is damaged press Replace press a disk.
Noise is audible at the squeezed-out pedal of coupling
The bearing of the coupling of switching off of coupling is faulty Check the bearing of the coupling of switching off of coupling, if necessary replace.
The disk of coupling beats on a press disk Replace a coupling disk.
Accruing and weakening noise during the pushing or towage or if the car slides at the included coupling
Difficult course of a quencher of krutilny fluctuations of a disk of coupling Restore a disk of coupling or replace it.
Connections of the coupling are weakened by Zaklepochnye Replace the coupling.
Too big imbalance of the coupling Replace the coupling and a coupling disk.
