10.2.7. Removal, check of a state and installation of components of coupling
Basket and the conducted clutch plate
Removal
Details of installation of components of coupling are shown on
the illustrations Coupling Design, applied on petrol models
and
the coupling Design applied on diesel models.
|
|
|
|
- By means of special adaptation block a flywheel from a provorachivaniye, then install the tool for centering of the conducted coupling disk.
|
- Release fixing bolts and separate a coupling basket from a flywheel.
|
|
Assembly of coupling has considerable weight, - try not to allow its falling at an otpuskaniye of the last bolts. |
- In case of need turn out eight fixing bolts and remove a flywheel (see the Head Dvigatel).
|
|
- For extraction from a pin of a bent shaft of the directing bearing use the hammer with sliding brisk.
|
|
|
Check
|
|
- Examine a working surface of a press disk on existence of zadir, cracks and traces of an overheat, - insignificant defects can be eliminated by means of a fine-grained emery paper. Check, are not broken off and whether petals of a diaphragm spring are bent. In case of need replace a basket.
- Estimate a condition of frictional overlays of the conducted disk and rivets of their fastening. Insignificant defects can be also eliminated by means of a fine-grained emery paper. At identification of signs of weakening of landing of rivets, and also in case of strong superficial pollution the disk is subject to replacement without fail.
|
|
- By means of Columbus estimate degree of wear of frictional slips, - the size of deepening of heads of rivets has to make not less than 0.3 mm.
|
|
|
- By means of the plunger dial measuring instrument (DTI) determine sizes of cross and radial side plays of a disk. If results of measurements exceed extreme admissible values (see Specifications of the Head the Transmission line), replace a disk.
|
|
|
Insignificant traces of corrosion can be eliminated by polishing with rigid felt. |
|
|
Installation
|
|
- Installation is made as it should be, the return to an order of dismantle of components, - before landing in a reception nest of a pin of a bent shaft the directing bearing should be greased with lithium lubricant (NGLI No. 2), - the zapressovyvaniye of the bearing is made by means of a suitable mandrel. Vents of a nave of the conducted disk are greased with organic molibdensoderzhashchy lubricant like Mori White TA No. 2, centering is made by means of special adaptation. Track observance of requirements of Specifications of the Head the Transmission line to efforts of tightening of carving fixture. In conclusion do not forget to take the aligning adaptation and the lock of a flywheel.

Release bearing
Removal
|
|
|
|
- Remove the release bearing from a main shaft of the transmission.
|
|
|
Check
|
|
In order to avoid washing away of factory stuffing do not wash out the release bearing in solvent at all! |
|
|
|
|
- Manually check freedom of a provorachivaniye of the bearing in both directions, estimate degree of wear of the working surfaces contacting to a fork of switching off of coupling and a diaphragm spring of a press disk. Replace the defective bearing.
|
|
|
Installation
|
|
|
|
- Grease the surfaces of the bearing with organic molibdensoderzhashchy lubricant like Mori White TA No. 2, then put him on the regular place in a dome of coupling and make sure of freedom of its rotation.
