Useful data and councils
The reasons of proslipping of coupling or its incomplete deenergizing by pressing a pedal
Coupling proslipping is shown that at quite serviceable engine the car badly overcomes liftings, slowly dispersed. It can be caused замасливанием or strong deterioration of disks, 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 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, 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 deenergizing of coupling. Noise can arise at deterioration or wrong adjustment of bearings, deterioration or wrong gearing of conic gear wheels. Strong knock in the specified places testifies to presence of the serious malfunction demanding an immediate stop of the car and repair of the unit.
The reasons of the complicated gear change or their spontaneous deenergizing
The complicated 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, to watch oil level in a transmission and in due time to change it.
