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
