Removal, installation and coupling check


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

2. Block a flywheel on a gear wreath a screw-driver and an opravka or the special tool (1). Unscrew bolts of fastening of a basket of coupling consistently on 1-1 1/2 turn so that to weaken tension.

If all bolts of fastening turn away at once, it can lead to damage of press springs and pins.

3. Completely turn out all bolts.
4. Take out a basket and a conducted disk of coupling.

Do not drop a basket and a conducted disk. It can lead after assembly to pro-slipping and difficulties at coupling switching off.

5. Wipe a flywheel.


1. Check press a disk on existence of places of an overheat and задиров.

2. Check integrity of press springs (an arrow on an accompanying illustration)

3. Check elastic connection between a press disk and a cover on existence задиров. Check reliability of zaklepochny connections. The coupling having damaged or weak zaklepochny connections, it is necessary to replace.

4. Check an adjacent surface of a press disk on existence of cracks, overheat and wear places. Press the disk, which surface has a deflection inside to 0.3 mm, can be established again into place. Check is carried out by means of a ruler and щупа.

5. Check a flywheel on existence of places of an overheat and задиров. If necessary replace. After each dismantling establish new mikrokapsyulirovanny bolts. If the flywheel is established old, replace fastening bolts if oil acts. A flywheel fix bolts cross-wise the moment of 105 Nanometers.
6. Smooth out press a disk and a flywheel a small emery paper.
7. The conducted disk made oily or having mechanical damages replace with the new.
8. Carefully clamp an overlay of coupling in a vice and measure thickness by a calliper. The minimum thickness should be not less presented in Specifications. Otherwise replace a coupling disk. The same is necessary for making in the presence of cracks.
9. In repair trucks the conducted disk is checked on palpation. Face palpation of a disk should not exceed 0.5 mm.

This check is necessary only when the old disk is established and there were difficulties with coupling switching off.

10. Remove the bearing of switching off of coupling from a pipe on a check point and check, address to the Section Removal and installation of the mechanism of switching off of coupling.

11. Check ease of a course of the roller bearing in cranked to a shaft. If necessary take the bearing a stripper and replace it with the new.


Before installation of new coupling remove with solvent a sheeting of a frictional surface of a press disk and in need of a flywheel.


1. Establish a conducted disk (2) and a basket with a press disk (3) on a flywheel (1).

The flat surface of a conducted disk should look towards a press disk. The conducted disk has “Getriebeseite” marking (the check point Party). The inscription at installation should be visible. A basket establish on the corresponding pins.

2. The conducted disk at installation should be aligned by the corresponding opravka (1) (for example, HAZET No. 2174) or old primary shaft of a check point.

3. Consistently tighten bolts of fastening of a basket on 1-1 1/2 turn so that press the disk was pressed. Watch that the basket at an inhaling of bolts evenly nestled on a flywheel. The moment of an inhaling depends on a class of durability of bolts which is beaten out on a head: bolts М8 have a class "8.8", the inhaling moment for them 25 Nanometers, the class "10.9" is tightened by the moment of 35 Nanometers.
4. Take out aligning tool.
5. If the stopper on a flywheel was established, take out it.

6. Grease shlitsevy grooves of primary shaft with a thin layer Microlube GL 261 greasing. Do not impose too much greasing, differently it can get on frictional surfaces of coupling that will lead to violations in its work.

7. Establish a check point, address to the Section Removal and RKPP and AT installation.
