8.3.3. Coupling details

Coupling details
1. Flywheel
2. Frictional disk
3. Coupling casing
4. Bolt
5. Release bearing
6. Fork
7. Spherical support of a fork
8. Cover

Places of check of wear of a frictional disk

1. Slips

2. Damping springs

3. Nave

4. Rivets

Wear of petals of a spring

 
1. Nomalny wear of petals
2. The increased wear
3. The increased wear of petals
4. Breakage or deformation of petals of a spring

Removal

PERFORMANCE ORDER
1. At the description of procedures it is meant that works are performed without removal of the engine.
2. Remove the working cylinder, take aside and fix.
3. You will hang out the engine and remove transmission. If the engine is propped up from below, then keep in mind that the oil receiver is located near the pallet and at deformation of the pallet access of oil to the engine can be blocked.
4. Record coupling, having inserted a mandrel.
5. Find adjusting tags (are designated by letters of X or O), at their absence designate the provision of coupling on a flywheel.
6. Gradually and evenly in the diagonal sequence release 6 bolts, action of springs will not weaken yet, then turn out bolts and remove a casing of coupling and a frictional disk.

Check

PERFORMANCE ORDER
1. As a rule replacement is demanded by only a frictional disk. Nevertheless it is necessary to examine a condition of all details.
2. Check a condition of a flywheel. It is recommended to remove a flywheel and to proshlifovat irrespective of a condition of a surface.
3. Check a condition of a surface of frictional slips, measure distance to heads of rivets of a disk which has to be not less than 1,5 mm. Check a condition of springs, weakening of rivets, existence of other signs of damages (see rice. Places of check of wear of a frictional disk). It is recommended to replace a disk irrespective of its state.
4. Together with a frictional disk as a rule also the release bearing changes.
5. Check a condition of a surface of a press disk, a diaphragm spring and petals of a spring (see rice. Wear of petals of a spring). Small defects of a disk can be polished a skin, at major defects replace coupling.

Installation

PERFORMANCE ORDER
1. Carefully clear a flywheel and coupling.
2. Establish coupling, having combined tags, and wrap bolts by hand. The tag of "flywheel side" (to a flywheel) has to be turned to a flywheel.
3. Center a disk by means of a mandrel which has to enter deepening of a flywheel, gradually and evenly, in a cross order, tighten coupling bolts.
4. Grease a flute of the release bearing and all rubbing surfaces with refractory lubricant. Install the release bearing.
5. Establish transmission and all removed details.
