6.1.3. Removal and installation of coupling

It will be required to you: a key "on 8" (the face head is more convenient), the big screw-driver...
... a mandrel for centering of the conducted disk (it is possible to make of a main shaft of the transmission, having removed gear wheels).
1. Remove the transmission (see. "Removal and installation of the transmission").
2. If you establish former press a disk, mark in any way a relative positioning of a casing of a disk and a flywheel to establish press a disk in same, as before removal, situation (for balancing preservation).
3. Establish a mandrel in an opening of a press disk.

Note
It is possible to remove coupling and without mandrel, but at the same time hold the conducted disk: it can drop out of a coupling casing.

4. Holding a flywheel the screw-driver from a provorachivaniye, turn out six bolts of fastening of a casing of a press clutch plate to a flywheel. Weaken an inhaling of bolts evenly: everyone on one turn of a key, passing from a bolt to a bolt on diameter.
5. Remove a coupling casing assembled with a press disk.
6. Remove the conducted disk together with a mandrel.
7. Cracks on details of the conducted disk are not allowed. Check wear of frictional slips 1. If heads of rivets 2 are deepened on distance less than 0,2 mm, the surface of frictional slips is greasy or rivet connections are weakened, then the conducted disk needs to be replaced. Check reliability of fixing of damping springs 3 in nests of a nave of the conducted disk, at the broken springs the disk needs to be replaced.
8. Check a beating of the conducted disk if at visual survey its buckling is revealed. If the beating exceeds 0,5 mm, replace a disk.
9. Examine the working surfaces of friction of a flywheel and a press disk, having paid attention to absence deep рисок, zadir, забоин, obvious wear tracks and an overheat. Replace defective knots.
10. External survey estimate a condition of a dish-shaped spring of 1 press disk. Existence of cracks on a spring is not allowed. Places and contact of petals of a spring with the bearing of switching off of coupling have to be in one plane and not have obvious wear tracks (wear should not exceed 0,8 mm). Otherwise replace press a disk assembled. When weakening rivet connections of 2 details of a casing and press disk replace press a disk assembled.
11. External survey estimate a condition of basic rings of a press spring. Rings should not have cracks and wear tracks. Otherwise replace press a disk assembled.
12. Before installation of coupling check ease of movement of the conducted disk on vents of a main shaft of the transmission. If necessary remove the causes of jamming or replace defective parts.
13. Pay attention that at installation of the conducted disk more acting part of a nave has to be sent to a casing of a press disk towards a press spring.
14. At coupling installation at first establish the conducted disk by means of a mandrel...
15.... then a casing of a press disk on three aligning pins also screw bolts of fastening of a casing to a flywheel.
16. Holding a flywheel the screw-driver from a provorachivaniye, evenly tighten bolts of fastening of coupling to a flywheel: everyone on one turn of a key, passing from a bolt to a bolt on diameter. The moment of an inhaling of bolts is specified in the appendix 1.
17. Remove a mandrel and install the transmission.
18. Install the lower end of a cable of the drive of switching off of coupling on the transmission and restore initial adjustment of a cable of the drive of switching off of coupling (see. "Replacement of a cable of the drive of switching off of coupling").

Note
Before restoration of initial adjustment of a cable it is necessary to bring to an initial state the mechanism of compensation of wear of overlays of the conducted clutch plate as at wear-out of a clutch plate the ram of the compensator of wear will remain in extreme lower situation. After installation of the new not worn-out conducted disk of length of a carving part of the lower tip of a cable can not be enough for recovery of the initial provision of a cable.
For reduction of the mechanism of compensation of wear in a starting position, having established the size L (see. "Replacement of a cable of the drive of switching off of coupling") between a lead and the lever of a fork of switching off of coupling, move a coupling pedal up to an emphasis — the spring of the mechanism will automatically return the ram to a starting position. Then again check the size L and if necessary adjust.
