"Than pro-slipping of coupling or its incomplete switching off when pressing a pedal can be caused?"
Pro-slipping of coupling is shown that at quite serviceable engine the car badly overcomes liftings, slowly dispersed. It can be caused by a zamaslivaniye of disks, their strong wear, decrease in elasticity of springs, lack of a free wheeling of a pedal of coupling.
Incomplete switching off of coupling causes difficulty and noise at gear shifting and can lead to premature failure of synchronizers and to the accelerated wear of teeths of a transmission. This malfunction arises at pollution, a distortion or deformation of disks, the wrong adjustment of position of levers of switching off, and also at too big free wheeling of a pedal of coupling more often.
It is necessary to mean that noise in a transmission is not always a consequence of incomplete switching off of coupling. This noise can arise at wear or the wrong adjustment of bearings, and also at wear or the wrong gearing of conic gear wheels. Strong knock in the specified places speaks about existence of the serious malfunction demanding an immediate stop of the car and repair of the unit.
"Than the zatrudnennost of gear shifting or their spontaneous switching off can be caused?"
Difficulty of gear shifting or their spontaneous switching off – result of wear of locks and clamps or a drive of the mechanism of gear shifting. Here without serious repair not to manage.
To warn similar malfunctions it is possible the next ways: periodically carefully to check reliability of fastening of all units and details of a power transmission, and also to watch oil level in a transmission and in due time to change it.
