14.5. A conducted disk of coupling
At coupling work the dust, with the maintenance of asbestos, unhealthy is formed, therefore at coupling clearing do not use compressed air and do not inhale a dust. Coupling details clear of a dust with use of a brake liquid or methyl spirit, and then wipe dry.
Fig. 8–8. A flywheel and coupling: 1 – a two-mass flywheel; 2 – a bolt, 60 Н·м + to tighten on a corner 180 °; 3 – a conducted disk of coupling; 4 – press a coupling disk; 5 – a bolt, 22 Н·м; 6 – the needle bearing
At installation it is necessary to use new bolts 2 (fig. 8–8).
Grease Slots a conducted disk with a thin layer of greasing G000100. The greasing layer should be thin and uniform, otherwise at coupling work excessive greasing will be rejected on working surfaces of coupling that can break its work.
Tightening of bolts 5 spend in regular intervals on a diagonal.
Remove a transmission.
Note a marker or a paint position of coupling in gathering in relation to a flywheel.
Fig. 8–9. Use of adaptations at removal and installation of a conducted disk of coupling: 3067 – the adaptation for fixing of a flywheel from проворачивания; 3176 – оправка for a centering of a disk of coupling
Using special tool VW-3067 or a screw-driver, for teeths of a gear wreath of a flywheel block it from проворачивания (fig. 8–9).
Gradually on a diagonal loosen the bolts of fastening of coupling in gathering, turning each bolt on a half-turn until action of a spring and bolts will stop can be unscrewed manually.
Remove press a disk, thus support a conducted disk that it has not dropped out.
Clear of a dirt the bearing of deenergizing of coupling, but thus do not use solvents.
Wipe a flywheel gasoline.
Fig. 8–10. Places of check press диафрагменной springs on deterioration
Check up a condition of a press disk of coupling. Development traces on the ends of a press spring should be no more than 0,3 mm (fig. 8–10).
Fig. 8–11. Check places заклепочных and spring connections
Check up reliability of spring connection between a press disk and a coupling casing. Scratches and absence or damage of rivets (fig. 8–11) are not supposed.
Check up press a disk on absence of cracks, пригара and deterioration of a surface.
Using a steel ruler and an edge probeа, check up неплоскостность a working surface of a press disk. Неплоскостность a press disk should not exceed 0,2 mm.
Check up a condition of a surface of a friction of a flywheel on absence of cracks, пригара and deterioration of a surface.
Check up a condition of frictional overlays of a conducted disk of coupling and at presence with them of traces of oil or mechanical damages replace a conducted disk.
Measure a thickness of overlays of a conducted disk of coupling. If their thickness of less admissible or if heads of rivets are close to a working surface, replace their or conducted disk of coupling.
Check up a condition of the bearing of deenergizing of coupling which should rotate easily, in regular intervals and silently and in which should be absent люфт. The working surface of the bearing influencing a press spring should be smooth, without cracks, local corrosion or development.
The faulty bearing of deenergizing of coupling can be defined, without removing it from the car for what it is necessary to press a coupling pedal at engine work. If by pressing of a pedal of coupling there is a noise, means, the bearing of deenergizing of coupling is faulty also it it is necessary to replace.
At installation new a conducted disk or a press disk of coupling remove from them anticorrosive protection.
At installation of a conducted disk watch, that on its frictional overlays even in insignificant quantities oil has not got. Therefore before installation by pure rags wipe привалочную a surface of a flywheel and a surface of a press disk, establish a conducted disk clean hands.
Grease Slots in a nave of a conducted disk with a thin layer of special greasing on a basis дисульфида molybdenum.
Establish a conducted disk on a flywheel so that the acting part of a nave of a disk has been directed outside, to a transmission.
Establish coupling in gathering, combining apertures in a casing of coupling with directing pins of a flywheel. At repeated installation before the removed press disk of coupling check up, that the labels put before removal were combined.
Tighten bolts of fastening of a casing of coupling so that the conducted disk of coupling has been pressed, but at the same time could move in the parties.
Using special the mandrel or an old primary shaft of a transmission, centre a disk of coupling concerning a flywheel.
The conducted disk of coupling can be centered special оправкой concerning a casing with a press disk in gathering.
After a centering of a conducted disk gradually on a diagonal tighten bolts of fastening of a casing of coupling by the moment 25 Н·м.
Take the mandrel from a conducted disk.
Grease шлицевую a part of a primary shaft of a transmission and directing plug of the bearing of deenergizing of coupling with a thin layer of special greasing on a basis дисульфида molybdenum.
Establish a transmission.
