8.2. Description and check of coupling
Models with RT are equipped with one-disk coupling of dry type with a diaphragm spring.
Components of standard assembly of coupling
||1 — Press a disk
2 — the Clutch plate
3 — the inclusion Lever
4 — the Release bearing
5 — the Finger with a spherical tip
6 — the Fixing spring of the lever
7 — the Bolt
Coupling is put in action by means of system of hydraulics.
When squeezing a pedal of coupling hydraulic liquid (under pressure created by the main cylinder of coupling) transfers power to the executive cylinder. As the executive cylinder is connected to a coupling switching off fork, this fork brings the release bearing into contact with petals of a press disk, bringing a clutch plate out of gearing.
The hydraulic system regulates coupling automatically therefore no additional adjustment of the drive or a pedal is required if only you did not replace the main cylinder of coupling and/or a pusher.
In the course of work with instructions there can sometimes be problems with the terminology relating to coupling components since different producers, sellers in shops of auto parts and sellers of cars call the same details differently. For example, the conducted disk is called both a clutch plate, and a frictional disk; the executive cylinder is called sometimes the working cylinder, etc.
Components with obvious damages should be replaced, but for cases when the cause of failure of system is not so obvious, several preliminary diagnostic checks are given below.
