"What can cause pro-slipping of coupling or its incomplete switching off when pressing a pedal?"
Pro-slipping of coupling is shown that at quite serviceable engine the car badly overcomes rises, slowly disperses. It can be caused by oiling 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 the transmission. This malfunction most often 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.
It must be kept in mind that noise in the 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. The 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.
"What can cause a zatrudnennost of gear shifting or their spontaneous switching off?"
Difficulty of gear shifting or their spontaneous switching off – result of wear of locks and clamps or the drive of the mechanism of gear shifting. Here not to do without serious repair.
It is possible to prevent similar malfunctions the next ways: periodically carefully to check reliability of fastening of all units and details of the power transmission, and also to watch oil level in the transmission and in due time to change it. |
