THE GENERAL DATA

MALFUNCTION
THE REASONS
The raised noise from outside couplings Noise is listened by pressing a pedal, in the end of a pedal course. The reasons are:
  – A warp of a heel of a press disk;
  – A small free wheeling of a pedal;
  – Insufficient greasing выжимного the bearing.
Faulty выжимной the bearing publishes a squealing sound during pressing a coupling pedal by the included transfer or throughout the first 5 sm of a course of a pedal. It is necessary to replace such bearing.
If the mechanism of a drive of coupling is badly greased, at a pedal full speed in both directions dry click is distributed.
Noise from the working engine amplify колоколообразным картером couplings and are transferred in salon. These noise, as a rule, are caused by a small free wheeling of a pedal and change at manipulations with a pedal.
Coupling proslipping (at inclusion of coupling the car is poorly dispersed) Proslipping is especially shown at dispersal from a place. It is checked as follows. On the working engine to press a brake pedal, to squeeze out coupling, to include one of the higher transfers and slowly to release a coupling pedal. If proslipping is absent, the engine will decay. Proslipping (проскальзывание a frictional disk) is caused by following reasons:
  – Deterioration of a press disk or a frictional disk;
  – замасливание a frictional disk;
  – An insufficient free wheeling of a pedal.
Incomplete deenergizing of coupling After deenergizing of coupling the disk of coupling and a transmission gear wheel continue to rotate short time. In normal conditions at moderate temperatures this time – about 3 seconds Incomplete deenergizing of coupling can be caused following reasons:
  – In a check point it is filled in маловязкое oil;
  – Wrong adjustment of the mechanism of deenergizing of coupling.
Coupling quickly fails Fast deterioration of coupling is caused by wrong skills of driving or driving under trying conditions. The reasons of reduction of term of operation of coupling are:
  – Frequent pressing a pedal of coupling and long keeping of a pedal;
  – Frequent keeping of the car on biases transfer inclusion, instead of a manual brake;
  – Fast отпускание coupling pedals.
