6.2.1. Possible malfunctions of the transmission and ways of their elimination

Possible malfunctions of the transmission and ways of their elimination
Cause of defect
Way of elimination
The complicated gear shifting
Incomplete switching off of coupling, availability of air in a hydraulic actuator of switching off of coupling or lack of liquid of the main cylinder of coupling
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
