GENERAL INFORMATION

MALFUNCTION
REASONS
The increased noise from coupling Noise is listened when pressing a pedal, at the end of the pedal course. Are the reasons:
  – distortion of a heel of a press disk;
  – low free wheeling of a pedal;
  – insufficient lubricant of the release bearing.
The faulty release bearing makes the squealing sound during pressing a coupling pedal by the included transfer or throughout the first 5 cm of the course of a pedal. Such bearing should be replaced.
If the mechanism of the drive of coupling is badly greased, then at a full speed of a pedal in both directions the dry click sounds.
Noise from the working engine amplify a bell-shaped case of coupling and are transferred to salon. These noise are, as a rule, caused by a low free wheeling of a pedal and change at manipulations with a pedal.
Coupling pro-slipping (at coupling inclusion the car poorly accelerates) Pro-slipping is especially shown at dispersal from the place. It is checked as follows. On the working engine to press a brake pedal, to squeeze out coupling, to include one of the highest transfers and to slowly release a coupling pedal. If pro-slipping is absent, then the engine will decay. Pro-slipping (slipping of a frictional disk) is caused by the following reasons:
  – wear of a press disk or frictional disk;
  – oiling of a frictional disk;
  – insufficient free wheeling of a pedal.
Incomplete switching off of coupling After coupling switching off the clutch plate and gear wheels of the transmission continue to rotate short time. In normal conditions at moderate temperatures this time – about 3 sec. Incomplete switching off of coupling can be caused by the following reasons:
  – in the check point low-viscous oil is filled in;
  – wrong adjustment of the mechanism of switching off of coupling.
Coupling quickly fails Bystry wear of coupling is caused by the wrong skills of driving or driving under trying conditions. Are the reasons of reduction of term of operation of coupling:
  – frequent pressing a pedal of coupling and long keeping of a pedal;
  – frequent keeping of the car on biases transfer inclusion, but not the emergency brake;
  – bystry otpuskaniye of a pedal of coupling.
