3.5. Diagnostics of malfunctions of coupling

REASON
ELIMINATION METHOD
Coupling pulls
Too low turns of idling To adjust turns
Bearings of the engine and the transmission failed To check, if necessary to replace
The transmission suspension bracket weakened To tighten fastening screws
Press the disk transfers the movement by breakthroughs To replace press a disk
The conducted disk does not correspond to the original of VW for this model of the engine To establish the conducted disk according to the original of VW
Discrepancy of axes of rotation of the crankshaft and shaft of the transmission To check centering of the engine and transmission
The release bearing of switching off works with one party To check the release bearing
Wrong arrangement of a guide of a rope of coupling To arrange correctly directing a rope
Coupling slips
The conducted disk is worn-out To check thickness of the conducted disk, if necessary to replace
The working cylinder * is had a snack To replace the working cylinder
Too membrane springs weakened To replace press a disk
The working cylinder * is untight To make external survey
Frictional slips hardened or were made oily To replace the conducted clutch plate
Coupling overheated To install spare parts according to the original of VW
Coupling is badly switched off
Snashivaniye of frictional slips as a result of attrition To replace the conducted clutch plate
The conducted disk gets jammed on driving to a shaft. Shlitsevy connection dry or is filled with attrition products To clean vents, to remove agnails, if necessary to remove a rust, to apply fresh lubricant, for example, the powder MoS2
Side fight of the conducted disk To check the conducted disk for HUNDRED, to replace
The main cylinder * is untight To observe at the squeezed-out coupling pedal whether brake fluid in a tank rages, if necessary to let out the air from system or to replace the main cylinder
The pedal of coupling is not squeezed out against the stop To check whether the coupling pedal against the stop is squeezed out, if necessary to cut a rug
The release bearing is faulty To check serviceability of the bearing
Air in a hydraulic system * To let out the air from coupling hydraulics
The mechanism of automatic adjustment of a rope of coupling is faulty To replace a coupling rope **
The directing bearing of a power shaft of the transmission on the crankshaft is faulty To replace the directing bearing on the crankshaft
The conducted disk is strongly bent or frictional slips are broken To replace the conducted disk
Noise in operating time of a pedal of coupling
The release bearing is faulty To check the release bearing, to replace
The conducted disk beats a press disk To replace the conducted disk
The amplifying, decreasing noise at enrollment and reduction of speed or at the movement with the switched-off coupling
The heavy course of a spring separator (the twisting shock-absorber) of the conducted clutch plate To replace the conducted disk
Rivet connections of coupling weakened To replace coupling
Coupling disbalance is too big To replace coupling and the conducted disk

* Treats only coupling with a hydraulic actuator
** Only for coupling with the mechanical drive
