9.9. Coupling details


1. Remove transmission.
2. Fix coupling, having inserted оправку.
3. Find adjusting labels, at their absence designate coupling position on a flywheel.
4. Gradually and in regular intervals release bolts, turn away bolts and remove coupling.


Frictional disk

1. A frictional overlay

2. Rivets

3. A label (it is put from outside a flywheel)

Deterioration of details of coupling

1. Normal deterioration of fingers

2. The strengthened deterioration of a diaphragm

3. The strengthened deterioration of fingers

4. Breakage or deformation of fingers диафрагменной springs

5. A warp of a press disk

6. The strengthened deterioration of a press disk

7. The strengthened deterioration of fingers

8. A place of the strengthened deterioration

Places of check of a leading disk of coupling

1. Bends of springs

2. Rivets

The sizes выжимного the bearing

And = 49 (0,4) mm (the bearing Fichtel&Sachs),

51,5 (1,0) mm (bearing SKF)

As a rule, replacement is demanded only by a frictional disk, however it is necessary to check up a condition of all details.

1. Remove a flywheel and check up a condition of the directing bearing.
2. If the bearing заедает at проворачивании replace it, having got a stripper and запрессовав оправкой.
3. Check up a condition of a surface of a frictional disk. At detection замасливания eliminate a leak, having replaced epiploons. At dismantling it is necessary to replace a frictional disk irrespective of its condition. Check up disk palpation to establish a condition of a press disk and a coupling casing.
4. Together with a frictional disk it is necessary to replace and выжимной the bearing. Remove выжимной the bearing (1) from a primary shaft, remove a spring (3) and remove the lever (2). Check up a condition of the lever and collect knot upside-down.
5. Check up deterioration of a rubbing surface of a flywheel, having put calibre. At strong deterioration a flywheel replace.
6. Check up a condition of a surface of a press disk, диафрагменной a spring and spring fingers. At dismantling, or after considerable run, it is recommended to replace coupling.


Correct position of the lever of deenergizing of coupling after assemblage

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. Preliminary establish a disk on (arrow) pins, using the labels put at dismantling.
3. Grease a flute выжимного the bearing (And and In – greasing places), rubbing surfaces of a plug and шлицы a primary shaft of a check point with refractory greasing. Establish the bearing. Establish transmission.
