Removal and coupling installation

On cars BMW of 3rd series self-established coupling (SAC - Self Adjusting Clutch) is applied. At removal and installation of this coupling it is necessarily necessary to wring out press a disk special tool BMW. The similar tool is available also for firm KLANN. Besides, or KLANN special aligning core BMW is necessary for installation of a conducted disk. Here working process with tool BMW application is described. If tool KLANN is applied, it is necessary to be guided by its description.


1 Remove РКПП, address to Section Removal and installation РКПП.

2 Fix a flywheel of the engine at a gear wreath a screw-driver and a core or special tool BMW-1. There is a similar tool of firm KLANN KL-0110.

Special tool BMW 21 2 160 or KLANN KL-0500-10 can be established only in the points shown on an illustration, otherwise coupling can to be damaged.

On an illustration coupling with the inserted aligning core is shown. The tool is not inserted yet.

3 Insert the adaptation for preliminary compression, address to an illustration. Tighten the screw-1 and check up reliability of its position.

4 Screw the screw-2 so that springs-3 were compressed against the stop. Turn away bolts of fastening of a basket of coupling consistently on 1 – 1.5 turns so that to unload press a disk.

If all bolts at once turn away, owing to a warp springs and pins of a basket of coupling and a flywheel can be damaged.

5 In summary completely turn out all bolts.
6 Take out a basket of coupling and a conducted disk.

Do not drop a basket and a conducted disk at removal, otherwise after assemblage there can be malfunctions in coupling work.

7 Wipe a flywheel.


1 Check up presence задиров on a flywheel. At their presence it is necessary to replace a flywheel. After each removal it is necessary to establish new special bolts. Tighten cross-wise bolts of fastening of a flywheel to a cranked shaft efforts presented in Specifications.

2 Check up ease of rotation of the directing bearing (the radial ball-bearing). Otherwise remove the bearing a stripper, for example, KLANN KL-0043-31 and запрессуйте against the stop the new bearing a hammer and a brass core against the stop.
3 Remove the bearing of deenergizing of coupling from a basic pipe on РКПП and check up, address to Section Removal and installation of the bearing of deenergizing of coupling.

4 Check up an adjoining surface of a press disk on presence of cracks, an overheat and deterioration. Press the disk having a deflection to 0.3 mm inside, can be устанавлен. Check is made by a ruler and щупом.

5 Smooth out press a disk and a flywheel a micrometric skin.
6 Check up springs of
