9.3. Diagnostics of malfunctions


Before starting repair of coupling, a transmission or the corresponding drives of management (except cases of obvious breakages), it is necessary to analyse attentively available signs of malfunctions and their possible reasons. Often external sign of malfunctions of coupling and a mechanical transmission is the complicated gear shifting (big efforts on the switching lever, shock inclusion of transfers or a gnash of gear couplings) or self-switching off of transfers. At the complicated gear shifting follows first of all, to check a course of a pedal of coupling and purity of switching off of coupling. If necessary to adjust a course of a pedal of coupling.

Course of a pedal of coupling
To check a coupling drive on existence люфтов in connections or worn-out hinges, deformations of arms, damage of a cable and other defects complicating moving of a pedal and reducing a course of a fork of coupling.

Check of purity of switching off of coupling

1. The engine works at frequency of idling, the transmission is in neutral situation, coupling is included.
2. To switch off coupling, to sustain a pause in 9 seconds and to include backing transfer. It should not be thus audible any gnash of teeths of gear wheels, and gnash existence at inclusion of transfer of a backing testifies to violation of adjustment or defects of a drive of coupling, a buckling of the leader or conducted disks or about breakages of details of coupling, for example, springs of dampers, frictional slips or elastic elements of a conducted disk, petals of a press diafragmenny spring or elastic leading plates of a press disk.
