8.2. Adjustment of a pedal of coupling
PUMPING OF HYDRAULIC SYSTEM OF THE DRIVE OF COUPLING
Any hydraulic system works normally if air is removed from it.
Prevention
During removal of air add only pure liquid recommended by the manufacturer.
The liquid used in the hydraulic drive dissolves paint and plastic therefore at hit of liquid on a paint and varnish covering of the car wash out its large number waters.
PERFORMANCE ORDER |
 |
1. Weaken the union of pumping and attach to it a hose. Arrange other end of a hose in the glass capacity of sufficient volume. |
2. Slowly press a coupling pedal. |
3. At the pressed pedal of coupling weaken the union of pumping and let out the air from hydraulic system. Tighten the union of pumping and release a coupling pedal. |
4. Repeat operations until there is a brake fluid without vials of air. |
Prevention
Bystry repeated pressing of a pedal of coupling in the field of B–C can lead to a pusher exit from the coupling cylinder case during pumping. It is necessary to press a coupling pedal only after its return to the top situation (A).

CONDUCTED AND PRESS CLUTCH PLATES
Coupling
1 – coupling switching off fork; 2 – coupling switching off bearing; 3 – bolt, 15–22 N • m; |
4 – press clutch plate; 5 – the conducted clutch plate. |
Check of a casing of coupling with a press disk
PERFORMANCE ORDER |
1. Check a diaphragm spring in places of contact with the bearing of switching off of coupling for lack of wear, cracks and define distinction of height of the ends of a diaphragm spring. With defects replace a casing of coupling with a press disk.
Distinction of height of the ends of a diaphragm spring: 0,5 mm |
2. Check press a disk for lack of cracks, a prigar and wear of a surface. |
3. Check reliability of rivet connections. |
|
Check of a clutch plate
PERFORMANCE ORDER |
1. Check reliability of rivet connections of frictional slips to a clutch plate. With defects replace a clutch plate. |
 |
2. Check a vystupaniye of frictional slips over heads of rivets. If the vystupaniye is less than admissible, replace a clutch plate. Vystupaniye: 1,1 mm
|
3. Check a condition of frictional overlays of a clutch plate and in the presence traces of oil or mechanical damages replace a clutch plate with them. |
4. Clear vents of a main shaft of the transmission and establish a clutch plate on a shaft. If the clutch plate moves on a shaft hardly or too big gap in shlitsevy connection, replace a clutch plate and / or an entrance shaft. |
|
Check of the bearing of switching off of coupling
Prevention
The bearing of switching off of coupling is tight, and it cannot be washed out.
PERFORMANCE ORDER |
1. Check a condition of the bearing of switching off of coupling which has to rotate easily, evenly and silently and in it there has to be no side play. The working surface of the bearing influencing a press spring has to be smooth, without cracks, local corrosion or development. |
2. The faulty bearing of switching off of coupling can be defined, without removing it from the car for what it is necessary to press a coupling pedal at the working engine. If when pressing a pedal of coupling additional noise appears, so the bearing of switching off of coupling is faulty, and it needs to be replaced. |
|
Check of a fork of switching off of coupling
PERFORMANCE ORDER |
If there is an uneven wear in points of contact of a fork of switching off of coupling with the bearing, replace a coupling switching off fork. |
