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