Removal and coupling installation

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


 REMOVAL

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

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

It is possible establish the special BMW 21 2 160 or KLANN KL-0500-10 tool only in the points shown on an illustration, otherwise coupling it 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 reliability of its situation.

4 Screw the screw-2-so that springs-3-were compressed against the stop. Unscrew 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 distortion 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 assembly there can be malfunctions in coupling work.

7 Wipe a flywheel.


 CHECK

1 Check existence задиров on a flywheel. At their existence 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 ease of rotation of the directing bearing (the radial ball-bearing). Otherwise remove the bearing a stripper, for example, KLANN KL-0043-31 and press against the stop the new bearing a hammer and a brass core against the stop.
3 Remove the bearing of switching off of coupling from a basic pipe on RKPP and check, address to the Section Removal and installation of the bearing of switching off of coupling.

4 Check an adjacent surface of a press disk on existence of cracks, an overheat and wear. Press the disk having a deflection to 0.3 mm inside, can be established. Check is made by a ruler and shchupy.

5 Smooth out press a disk and a flywheel a micrometric skin.
6 Check springs of a basket of coupling on existence of damages.
7 Greasy or mechanically damaged disk replace.

8 Measure by a calliper thickness of frictional overlays of a conducted disk. For this purpose measure distance between a frictional surface and heads of rivets - And-.

The distance should be measured at a closing head - And - instead of at a mortgage head of a rivet - In-. The distance should remain not less than 1.0 mm. Otherwise it is necessary to replace a disk.



 INSTALLATION

At installation of new details the varnish for protection against corrosion should be removed only from frictional surfaces of a press disk and a flywheel. Not огружайте a coupling basket in solvent also do not blow the compressed air, functioning of the mechanism of adjustment of coupling otherwise is not guaranteed.

Installation of a basket of the coupling which were in use

1 Shift back an adjusting ring. For this purpose establish a coupling basket together with the tool for a preliminary tightness on a pure lining. Fix an adjusting ring a screw-driver at one of grooves-1-

2 Weaken the screw-2-the tool for a preliminary tightness so that it was possible to turn an adjusting ring a screw-driver.

The clamp-3-is inserted only when the adjusting ring is compressed.


3 Turn to the left against the stop a screw-driver adjusting a ring at press elements-1-.

4 Insert a clamp-3-into a groove. Thus, the adjusting ring is fixed.
5 Screw the screw of the tension tool so that the diafragmenny spring in a basket was pressed against the stop.
6 Insert into a flywheel a coupling disk.

Insert a disk correctly. For this purpose the disk of coupling has “Getriebeseite” marking (the check point Party).


7 Align a coupling disk in a flywheel the adaptation - 1-, for example, BMW 21 2 142 or KLANN KL-0500.

The bolt-2-serves for adaptation removal on the established basket.

8 Put a coupling basket on the corresponding pins. Tighten bolts of fastening of a basket of coupling consistently on 1 – 1.5 turns so that it was fixed. Watch that at an inhaling of bolts the basket of coupling sat down on a flywheel evenly. The moment of an inhaling depends on a class of durability of bolts which is beaten out on a head of bolts. Address to Specifications.

9 Weaken the screw the tool for a preliminary tightness so that the spring in a basket was completely unloaded. Weaken the screw-1-and remove the adaptation.

10 Take out aligning adaptation with a bolt - 2-of a conducted disk. For this purpose screw a bolt and pull for it.

Installation of a new basket of coupling

11 Insert into a flywheel a conducted disk.

Insert a disk in the correct situation. For this purpose a disk “the check point Party” has marking.

12 Align a coupling disk in a flywheel the adaptation - 1-for the directing bearing in cranked to a shaft, for example, the BMW 21 2 142 or KLANN KL-0500 adaptation.

The bolt-2-serves for adaptation removal in the established basket of coupling.

13 Put a coupling basket on the corresponding pins. Tighten bolts of fastening of a basket of coupling consistently on 1 – 1.5 turns so that the disk was fixed. Watch that at an inhaling of bolts a basket of coupling it was involved in a flywheel evenly. The moment of an inhaling depends on a class of durability of bolts which is beaten out on a head of bolts, address to Specifications.

It is authorized to delete a lock element-1-only at the fixed basket of coupling. Turn out a lock element a face key - 2-on 14 mm rotation clockwise.

At a reversing of a lock element the diafragmenny spring can publish characteristic noise to which it is not necessary to pay attention.


14 Extend aligning adaptation a bolt from a conducted disk. For this purpose screw a bolt and pull for it.

15 Remove aligning adaptation from a flywheel.

16 Grease grooves of shlitsevy connection of primary shaft of RKPP with a thin layer of ESSO UNIREX greasing.

Do not put too much greasing, otherwise it can get on frictional surfaces of coupling and cause coupling failures. The necessary amount of greasing corresponds to about a size of grain of fig. Then move in different directions conducted disk on RKPP shaft so that the nave easily went on a shaft. Surpluses of greasing remove.

17 Establish RKPP, address to the Section Removal and RKPP installation.
