Surface of a press disk

1. Normal wear

2. The strengthened wear

3. The strengthened wear of fingers

4. Breakage or deformation of fingers of a spring


Dust from wear of slips delete with a special cleaner. Application of gasoline or solvent is not allowed.

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


1. Lift a car front.
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 the maslopriyemnik is located near the pallet and can be easily damaged at pallet deformation.
4. The fork and vyzhimny can be not removed the bearing yet.
5. To fix coupling, use an opravka.
6. Fix coupling.
7. Find adjusting labels (letters X or About), at their absence designate the provision of coupling on a flywheel.
8. Gradually and evenly release 6 bolts, unscrew bolts and remove coupling.


1. As a rule replacement is demanded by only a frictional disk. However, if the disk zamaslivaniye is revealed, it is necessary to find the reason and to eliminate.
2. Check existence on a surface of a flywheel of wear tracks, vykrashivaniye of metal, deep development. It is recommended to remove a flywheel and прошлифовать irrespective of a surface condition.
3. Check a condition of the directing bearing.
4. Check a condition of a surface of a frictional disk, springs, weakening of rivets.
5. Together with a frictional disk the bearing changes also vyzhimny.
6. Check a condition of a surface of a press disk, a diafragmenny spring and spring fingers (see fig. Surface of a press disk). 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. Center a disk by means of an opravka which should enter into the directing bearing and gradually and evenly tighten coupling bolts in an order specified a photo.
3. Grease a flute of the vyzhimny bearing, rubbing surfaces of a fork and a shlitsa of primary shaft of a check point with refractory greasing. Establish the bearing. Establish transmission.
