Noise in a transmission

Eventually emergence of noise in KP is possible. In that case you should check for a start oil level in KP.

  • If at inclusion of transfers there is the howling sound which tone changes at increase or "gas" reduction, worn-out gear connection of the corresponding pair of gear wheels can be the reason of this phenomenon.
  • At noise on all transfers by the reason the main transfer or bearings of shaft of KP is.
  • The gnash arising only after achievement of KP of working temperature, indicates palpation of blocking rings of the synchronizer. As soon as oil becomes more fluid, it breaks from a synchronizer ring all the time on the same site.

 Help: workshops, as a rule, seldom are solved on repair or major maintenance of KP, and advise to replace a faulty box new. Financially installation of the second-hand unit acquired on dismantling of cars, however, is in most cases more expedient. Thus it is necessary to pay attention to the correct alphabetic marking of KP. It is beaten out on KP above. Besides, there day, month and year of manufacturing are specified, and year is specified by only the last figure.
