Surface of a press disk

1. Normal deterioration

2. The strengthened deterioration

3. The strengthened deterioration of fingers

4. Breakage or deformation of fingers of a spring

The prevention

Dust from deterioration of overlays delete a special cleaner. Gasoline or solvent application is not supposed.

At the description of procedures it is meant that works are carried out without engine removal, and transmission is removed.


1. Lift car redock.
2. Remove the main cylinder.
3. Will hang out the engine and remove transmission. If the engine is propped up from below keep in mind that маслоприемник is located near to the pallet and can be easily damaged at pallet deformation.
4. The plug and выжимной can to be removed the bearing yet.
5. To fix coupling, use оправку.
6. Fix coupling.
7. Find adjusting labels (letters Х or), at their absence designate coupling position on a flywheel.
8. Gradually and in regular intervals release 6 bolts, turn away bolts and remove coupling.


1. As a rule replacement is demanded only by a frictional disk. However, if it is revealed замасливание a disk it is necessary to find the reason and to eliminate.
2. Check up presence on a surface of a flywheel of wear tracks, выкрашивания metal, deep development. It is recommended to remove a flywheel and прошлифовать irrespective of a surface condition.
3. Check up a condition of the directing bearing.
4. Check up a condition of a surface of a frictional disk, springs, easing of rivets.
5. Together with a frictional disk varies and выжимной the bearing.
6. Check up a condition of a surface of a press disk, диафрагменной a spring and spring fingers (fig. the Surface of a press disk see). Small defects of a disk can be polished a skin, at major defects coupling replace.


1. Carefully clear a flywheel and coupling. Establish coupling, having combined labels and wrap bolts by hand.
2. Centre a disk with the help оправки which should enter into directing bearing both gradually and in regular intervals tighten coupling bolts in an order specified in a photo.
3. Grease a flute выжимного the bearing, rubbing surfaces of a plug and шлицы a primary shaft of a check point with refractory greasing. Establish the bearing. Establish transmission.
