Removal, installation and coupling check



1. Remove RKPP, address to the Section Removal and check point installation.

2. Unscrew Torx screws of fastening of a basket of coupling (an arrow on an illustration) one by one on 1-1Ѕ turn so that to unload a disk. To exclude flywheel rotation at an otvorachivaniye of screws, hold it a screw-driver or a clamp. HUNDRED apply the special tool (1) to this purpose.

If Torx screws turn away non-uniformly, it can lead to damage of diafragmenny springs.

3. Then unscrew fastening screws completely.

Remember or write down the provision of a conducted disk of coupling that at assembly to establish it in former situation.

4. Take out a basket and a conducted disk of coupling.

 Do not allow falling of disks at removal since otherwise after installation there can be problems in coupling work.



1. Check press a disk on existence of places of an overheat and flutes, if necessary replace.

2. Check wear of uvulas of diafragmenny springs and their height, if necessary carefully turn in the ends of springs.

Wear of springs should not exceed 0.3 mm.

3. Check connections of a press disk and a basket on existence of cracks, and zaklyopochny connections on durability. A basket with the damaged or weak zaklyopochny connections replace.
4. Before installation of new coupling remove from frictional surfaces with solvent a sheeting of new coupling. Then smooth out a rough emery paper frictional surfaces of conducted and press disks.
5. The greasy or mechanically damaged disk - replace.
6. Check the bearing of switching off of coupling in a transmission casing on noise existence, a leakage and wear, if necessary replace.



1. Clear shlitsevy connections of a disk of coupling and primary shaft of a transmission and grease with a thin layer of MoS2-greasing, for example, MOLYKOTE BR 2.

Do not put too much greasing, otherwise it can get on frictional surfaces of coupling that will result in malfunctions in coupling work. The necessary amount of greasing corresponds to the size of grain of corn.

At engines with a two-mass flywheel shlitsevy connection has a covering nickel that excludes need of greasing. A sign of a two-mass flywheel is lack of dempfiruyushchy springs.

2. Center a disk of coupling with the help of the corresponding drift, for example, HAZET 2174 or an old secondary shaft of a transmission. If the disk of coupling is not centered, later it will not be possible to enter a secondary shaft of a transmission.

3. Establish a basket of coupling with the aligned disk of coupling on the corresponding pins in a flywheel.
4. Screw by hand screws of fastening of a basket, then tighten cross-wise in stages, each time on 1-1 Ѕ a turn.

At an inhaling watch that the basket evenly nestled on a flywheel. The moment of an inhaling is specified in Specifications.

5. Take out aligning drift.
6. Remove the lock tool on a flywheel if it was established.
7. Establish to the place of RKPP, address to the Section Removal and check point installation.
