Removal
| PERFORMANCE ORDER |
| 1. Remove transmission. |
|
2. Record coupling, having inserted a mandrel. |
|
3. Find adjusting tags, at their absence designate the provision of coupling on a flywheel. |
|
4. Gradually and evenly release bolts, turn off bolts and remove coupling. |
|
Check
Frictional disk
|
|
1. Frictional slip
2. Rivets
3. A tag (it is put from a flywheel) |
Wear of details of coupling
|
|
1. Normal wear of fingers
2. The increased wear of a diaphragm
3. The increased wear of fingers
4. Breakage or deformation of fingers of a diaphragm spring
5. Distortion of a press disk
6. The increased wear of a press disk
7. The increased wear of fingers
8. The place of the increased wear |
Places of check of a drive plate of coupling
|
|
1. Bends of springs
2. Rivets |
Sizes of the release bearing
|
|
And = 49 (±0,4) mm (Fichtel&Sachs bearing),
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, then replace it, having got a stripper and having pressed a mandrel. |
| 3. Check a condition of a surface of a frictional disk. At detection of oiling eliminate a leak, having replaced epiploons. The frictional disk when dismantling should be replaced irrespective of its state. Check a disk beating to establish a condition of a press disk and a casing of coupling. |
|
4. Together with a frictional disk it is necessary to replace also the release bearing. Remove the release bearing (1) from a main 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 the rubbing flywheel surface, having put caliber. At strong wear replace a flywheel. |
|
6. Check a condition of a surface of a press disk, a diaphragm spring and fingers of a spring. When dismantling, or after the considerable run, coupling is recommended to be replaced. |
|
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 tags, and wrap bolts by hand. |
|
2. Center a disk by means of a mandrel which has to enter the directing bearing and gradually and evenly tighten coupling bolts. Previously establish a disk on pins (arrow), using the tags put when dismantling. |
|
3. Grease a flute of the release bearing (And yes In – places of lubricant), the rubbing surfaces of a fork and a vent of a main shaft of the check point with refractory lubricant. Install the bearing. Establish transmission. |
