8.1.3. Press a coupling disk
THE GENERAL DATA

The coupling device

1. A coupling disk
The casing of springs is turned to a press disk
2. A flywheel
Check up adjusting pins
On a surface of a friction of overlays of coupling there should not be scratches, oils or greasings
Use the tool 10-201 for installation removal /
3. A bolt, 30 Н.м. + 1/4 (90 ) a turn
The additional quarter (90 ) a turn can be carried out in two stages on 45
Always replace a bolt: DO NOT USE REPEATEDLY
Cover a carving of a new bolt with fixing structure
4. Press a disk
5. 25 Н.м.

Replacement

PERFORMANCE ORDER
1) fix a flywheel
2) oslabte/clamp bolts in regular intervals and on a diagonal; use directing tool And = 3176
3) reinstall the holder 10-201 in the course of a tightening of bolts

The prevention

Press the disk should contact completely with a flywheel before installation of assembly bolts.


4) for coupling repair remove a transmission

The prevention

Press disks and coupling disks have a corrosion-resistant coating, therefore it is necessary to clear only rubbing surfaces. Otherwise service life of disks will considerably be reduced.


5) do not apply efforts at installation of a press disk since it is possible to damage adjusting pins / of an aperture

Check

PERFORMANCE ORDER
1) check up about cracks, burning and deterioration traces
2) maximum internal конусность: 0.3 mm
3) check up overlays and шлицы about deterioration, and a rivet – about rigidity
4) check up the ends of springs of a diaphragm (are specified by arrows)
5) as much as possible admissible deterioration: to half of spring

The prevention

In need of replacement choose press a disk and a coupling disk under the catalogue of spare parts, using an alphabetic code and engine number.
