9.1.3. Coupling check


1. Remove a transmission.
2. One by one weaken fixing bolts of a press disk of coupling respectively on 1–1,5 turns until the disk will be weakened press.


If fixing bolts get out at once completely, the tarelchaty spring can be damaged.

3. That at the same time when weakening bolts the flywheel did not turn, stop it a screw-driver.
4. After that completely unscrew bolts.
5. Take press a disk and a coupling disk.

At extraction do not drop them, differently after assembly there can be the difficulties connected with a derganye and separation of coupling.

6. Blow the compressed air a flywheel inside or wipe it a rag moistened in gasoline.


1. Check press a coupling disk on lack of cracks пережога and scratches.
2. Survey a tarelchaty spring on lack of cracks.
3. Check on wear and uniformity of height ledges of a tarelchaty spring (arrow), if necessary carefully level them pincers.


Wear can make at most 0,3 mm.

4. Check a flywheel on lack of cracks пережога and scratches.
5. Process press a disk of coupling by a rough grinding skin.
6. Replace made oily, covered with konsistentny greasing or mechanically damaged disks of coupling.
7. Measure thickness of overlays of a disk of coupling. New: 3,6-4,0 mm from each party of a slip. If the wear limit in 2,6-3,0 mm on each party of a frictional slip is already reached, replace a coupling disk. As arrive in the presence of cracks on frictional slips.
8. Check on lack of wear tracks and grinding in lock bolts, amortization windows, springs of torsion and the plug (arrows).
9. Remove and check the bearing of the coupling of switching off of coupling from a tubular support on a forward cover of a transmission.
10. In a repair truck it is possible to check a coupling disk on palpation. Lateral palpation at a disk of coupling can make at most 0,5 mm.

This check is required only if it is necessary to establish again an old disk of coupling and coupling was incorrectly switched off earlier.


1. Get a disk of coupling and press a coupling disk on a flywheel and center their connecting strezhny or the aligning HAZET 2174 tool.


At engines with a two-case flywheel the gear wreath of a disk of coupling проникелирован and consequently does not need greasing.

2. One by one consistently tighten fixing bolts to a press disk of coupling on 1–1,5 turns until press the disk to the full will not be fixed. Inhaling moment: 25 N of m. Then remove the central opravka.

Pay attention to that at a tightening of bolts press the disk evenly and without agnails was involved in a flywheel.

3. Mount a transmission.
