Removal
| PERFORMANCE ORDER |
| 1. Remove transmission. |
|
2. Fix coupling, having inserted an opravka. |
|
3. Find adjusting labels, at their absence designate the provision of coupling on a flywheel. |
|
4. Gradually and evenly release bolts, unscrew bolts and remove coupling. |
|
Check
Frictional disk
|
|
1. Frictional slip
2. Rivets
3. A label (it is put from a flywheel) |
Wear of details of coupling
|
|
1. Normal wear of fingers
2. The strengthened wear of a diaphragm
3. The strengthened wear of fingers
4. Breakage or deformation of fingers of a diafragmenny spring
5. Distortion of a press disk
6. The strengthened wear of a press disk
7. The strengthened wear of fingers
8. A place of the strengthened wear |
Places of check of a leading disk of coupling
|
|
1. Bends of springs
2. Rivets |
Sizes of the vyzhimny bearing
|
|
And = 49 (±0,4) mm (bearing Fichtel&Sachs),
51,5 (±1,0) mm (SKF bearing) |
As a rule, replacement is demanded by only a frictional disk, however it is necessary to check a condition of all details.
| PERFORMANCE ORDER |
|
1. Remove a flywheel and check a condition of the directing bearing. |
|
|
| 2. If the bearing jams at a provorachivaniye, replace it, having got a stripper and having pressed an opravka. |
| 3. Check a condition of a surface of a frictional disk. At detection of a zamaslivaniye eliminate a leak, having replaced epiploons. When dismantling it is necessary to replace a frictional disk irrespective of its condition. Check 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 vyzhimny the bearing. Remove vyzhimny the bearing (1) from primary shaft, remove a spring (3) and remove the lever (2). Check a condition of the lever and collect knot upside-down. |
| 5. Check wear of a rubbing surface of a flywheel, having put calibre. At strong wear a flywheel replace. |
|
6. Check a condition of a surface of a press disk, a diafragmenny spring and spring fingers. When dismantling, or after considerable run, it is recommended to replace coupling. |
|
Installation
The correct position of the lever of switching off of coupling after assembly
| PERFORMANCE ORDER |
| 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. Previously establish a disk on (arrow) pins, using the labels put at dismantling. |
|
3. Grease a flute of the vyzhimny bearing (And and In – greasing places), rubbing surfaces of a fork and a shlitsa of primary shaft of a check point with refractory greasing. Establish the bearing. Establish transmission. |
