Possible malfunctions of the transmission and ways of their elimination
|
|
Cause of defect
|
Way of elimination
|
The complicated gear shifting
|

|
To bring to norm liquid level in a tank of the main cylinder and to pump over system of a hydraulic actuator of coupling
|
Weakening of an inhaling of lock bolts of heads or forks of the mechanism of switching
|
To tighten lock bolts
|
Agnails on an internal surface of teeths of couplings of inclusion of transfers
|
To smooth out agnails
|
Openings under pins in the switching lever case are broken
|
To replace the case of the lever of switching or to repair, having chiseled openings and having pressed step pins
|
Violation of synchronization of inclusion of transfers (inclusion with a crash)
|
|
Wear of a carving of a conic surface of blocking synchronizer ring
|
To remove the transmission from the car. To remove a forward case and to check the probe a gap between the blocking ring and a pryamozuby wreath. If a gap less than 0,3 mm then to establish the new blocking ring, having ground in it to a surface of the corresponding gear wheel before receiving a surface of a prileganiye not less than 80%
|
Deformation of the blocking ring (the ring is not stopped on a cone during the pressing and turn by a hand)
|
To establish the new blocking ring, having ground in it to a surface of the corresponding gear wheel before receiving a surface of a prileganiye not less than 80%. KT TU-06283-76 Pritirochny paste
|
Spontaneous switching off of transfers
|
|
Weakening of an inhaling of nuts of fastening of the transmission to a case of coupling or bolts of fastening of cases of the transmission
|
To tighten nuts or bolts
|
Wear of end faces of teeths of couplings of inclusion of transfers or wear of teeths of a shlitsevy wreath on gear wheels of the 1st, 2nd, 3rd, 5th transfers, a backing and on primary to a shaft
|
To replace worn-out details
|
Weakening of springs of clamps
|
To establish springs with load (60+15) N (6+1,5) kg · with at compression to 10 mm
|
Noise in the transmission
|
|
Wear of bearings
|
To replace bearings
|
Breakage of teeths of gear wheels
|
To replace the damaged gear wheels
|
Wear of a working surface of teeths of gear wheels
|
To replace the damaged gear wheels
|
The lowered oil level in a case
|
To add oil to normal level
|
Coaxiality of a bent shaft and case of coupling is broken
|
To check and restore coaxiality (see <repair of the engine>)
|
Oil leak from the transmission
|
|
Wear of epiploons
|
To replace epiploons
|
Pollution of a sapun or its damage
|
To clear сапун of dirt or to replace new
|
Leakage of caps and traffic jams of cases
|
To restore tightness of traffic jams
|
Leakage of caps and traffic jams of a clamp of the mechanism of gear shifting
|
To restore tightness of caps and traffic jams
|
Weakening of fastenings of details of a forward cover, forward and back cases and case of the lever of gear shifting
|
To tighten bolts and nuts of fastenings
|
Damage of laying or existence забоин on privalochny surfaces
|
To replace laying, to smooth out zaboina and to grind in privalochny surfaces
|
Wear of the stalebabbitovy plug of a back case
|
To replace a back case or to press in it and to chisel to diameter 3+0,015mm coaxially with an opening under the ball bearing within no more than 0,05 mm the stalebabbitovy plug
|
At inclusion of all transfers the turning moment is not transferred to the driveshaft
|
|
Weakening of landing of gear wheels on intermediate to a shaft
|
To replace an intermediate shaft or to weld a gear wheel on an intermediate shaft
|
At inclusion of the 2nd, 3rd or 5th transfer the turning moment is not transferred to the driveshaft
|
|
Weakening of landing of a gear wheel of the 2nd, 3rd or 5th transfer on intermediate to a shaft
|
To replace an intermediate shaft assembled or to weld a gear wheel of the 2nd, 3rd or 5th transfer on an intermediate shaft
|
