GENERAL INFORMATION

REASON
WAY OF ELIMINATION
Coupling twitches
Too low frequency of rotation of a shaft of the engine in the idling mode Check system of regulation of frequency of rotation of a shaft of the engine in the idling mode.
The bearing of a shaft of the engine and the bearing of a shaft of the transmission are faulty Check, if necessary replace.
Unevenly the disk adjoins press Replace press a disk.
Not company clutch plate Establish a company clutch plate.
Coupling slips
The clutch plate wore out Check clutch plate thickness, if necessary replace a clutch plate.
The restrictive emphasis of a pedal of coupling is faulty Check a restrictive emphasis of a pedal of coupling.
Too low tension of a dish-shaped spring Replace press a disk.
Jams the distributive cylinder Replace the distributive cylinder.
The distributive cylinder is untight Carry out visual control.
The frictional slip hardened and was made oily Replace a clutch plate, remove the cause of pollution.
Coupling was overheated Establish company details.
Coupling is incorrectly separated
The sensor cylinder is untight Check the sensor cylinder, charge to squeeze out a pedal and check whether liquid in a receiver began to boil.
Air in system of coupling Remove air from the drive of management of 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.
The frictional slip because of attrition sticks Replace a clutch plate.
The clutch plate jams on primary transmissions, melkoshlitsevy connection dried or sticks Clear melkoshlitsevy connection, remove agnails, if necessary remove a rust.
The clutch plate has a side beating Charge to check a clutch plate, if necessary replace.
The aligning bearing of a main shaft of the transmission on cranked to a shaft is faulty Replace the aligning bearing on cranked to a shaft.
Difficult rotation of the bearing of the coupling of switching off of coupling or heavy course of a pedal Replace the coupling switching off coupling bearing, the pedal has to be squeezed out easily.
The pedal of coupling does not come back or comes back with delay
Air in system of coupling Remove air from the drive of management of coupling.
The old (oxidized) brake fluid Replace brake fluid.
Jams the distributive cylinder or the cylinder sensor Replace the distributive cylinder or the cylinder sensor.
The clutch plate is worn-out Replace a clutch plate.
Because of an overheat the clutch plate is damaged press in view of what the effort of its reset weakened Replace press a disk.
Noise at the squeezed-out coupling pedal is heard
The coupling switching off coupling bearing is faulty Check the coupling switching off coupling bearing, if necessary replace.
The clutch plate beats a press disk Replace a clutch plate.
The accruing and weakening noise during the pushing or towage or if the car slides at the included coupling
Difficult course of a quencher of tortional fluctuations of a clutch plate Restore a clutch plate or replace it.
Rivet connections of the coupling are weakened Replace the coupling.
Too big imbalance of the coupling Replace the coupling and a clutch plate.
