7.2. Replacement of a disk or a leading part of coupling

THE GENERAL DATA

The lever of deenergizing of coupling

1 – the fastening plug on the spherical hinge, 2 – развальцовывание ledges of fastening of the plug on the lever of deenergizing of coupling

Coupling acts in film after transmission removal.

Removal

PERFORMANCE ORDER

1. To designate position of a leading part of coupling concerning a flywheel using a marker or a paint. 2. In regular intervals and consistently, on a diagonal to weaken bolts of fastening of a press disk, turning them half a turn, pressure of a spring and bolts will not act in film yet can be unscrewed manually. 3. By means of the lever to remove leading knot of coupling from directing probes and to remove a coupling disk.

Check

PERFORMANCE ORDER

The prevention It is desirable to replace a disk of the coupling conducting knot of coupling and выжимной the bearing if though one of them demands replacement in the complete set. For washing of leading knot and a coupling disk it is possible to use a cleaner of brakes or methyl spirit. 1. To check up overlays of a disk of coupling on deterioration, mechanical damages or pollution by oil. 2. In the presence of these defects it is necessary to replace a coupling disk. 3. If frictional overlays in a good condition also are not worn out to grooves, springs damperов are reliably fixed and заклепочные connections are not loosened, the coupling disk can be established in the car. 4. If the coupling disk is polluted by oil, to check up the left oil consolidation of a cranked shaft or a primary shaft of a transmission. If necessary to replace sealing rings before installation of a new disk of coupling. 5. To check up knot of a leading disk on deterioration of a press disk, mechanical damages, reliability заклепочного connections, damage диафрагменной coupling springs. If the diaphragm spring is worn out or damaged or there is a suspicion that elasticity of a spring it is necessary to replace knot of a leading disk has changed. 6. To check up working surfaces of a press disk and a flywheel, interfaced to overlays of a disk of coupling. They should be pure, flat, not have scratches and development. At presence коробления from a heat or cracks it is necessary to replace them. 7. To check up выжимной the bearing which should rotate easily, in regular intervals and silently. The working surface of the bearing influencing a press spring, should be smooth, without cracks, local corrosion or development. If there are these defects, выжимной it is necessary to replace the bearing. On leading knots of coupling of the second type it is necessary to replace all knot.

Aligning оправка a coupling disk


Installation

PERFORMANCE ORDER

1. To establish a coupling disk that the nave of springs has been directed outside from a flywheel. On a coupling disk the marks specifying correctness of installation of a disk of coupling can be put. 2. To establish leading knot of coupling on the labels made at removal. Manually to tighten bolts of fastening of leading knot of coupling. 3. Оправкой to centre a coupling disk that the primary shaft of a transmission has passed through grooves in the centre of a disk of coupling. 4. The centering of a disk of coupling can be made, using special the mandrel or independently made the mandrel which sizes correspond to a peppery shaft of a transmission. 5. In regular intervals and in diagonal sequence to tighten bolts of fastening of a leading part of coupling. 6. To establish a transmission. The prevention If the lever of deenergizing of coupling acted in film, it is necessarily necessary to replace the plastic plug (1) (fig. the Lever of deenergizing of coupling see). For this purpose follows:   – To establish the new plug on the lever of deenergizing of coupling;   – To heat up ledges (2) so that to soften plastic;   – Easily развальцевать ledges;   – To grease the plug (1). 7. A shaft of coupling and the plug выжимного the bearing to grease with a thin layer of special means Molykote 321 R. 8. To establish a transmission. 9. To adjust knot of management of coupling.
