7.1.2. A coupling disk

THE GENERAL DATA

Use of adaptations at removal and installation of a disk of coupling

3067 – the adaptation for fixing of a flywheel from проворачивания 3176 – оправка for a centering of a disk of coupling

---

The prevention

At coupling work, the dust which contains asbestos, unhealthy is formed, therefore at coupling clearing do not use compressed air and do not inhale a dust. Clearing of details of coupling of a dust make with use of a brake liquid or methyl spirit. After clearing of details of coupling with использовани I eat methyl spirit or a brake liquid wipe details dry.

Removal

PERFORMANCE ORDER

1. Remove a transmission. 2. Note position of leading knot of coupling in relation to a flywheel, using a marker or a paint. 3. Using special tool VW-3067 or a screw-driver, for teeths of a gear wreath of a flywheel block a flywheel from проворачивания, Fig. Use of adaptations at removal and installation of a disk of coupling) see 4. Gradually in diagonal sequence ослабьте bolts of fastening of leading knot of coupling, turning each bolt on half of turn until action of a spring and bolts will stop can be unscrewed manually. 5. Remove press a disk, thus support a coupling disk that it has not fallen. 6. Wipe a flywheel with gasoline use.

Check

Places of check press диафрагменной springs on deterioration


Directions in which it is necessary to check a condition выжимного the bearing

PERFORMANCE ORDER

1. 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. of the Place of check press диафрагменной springs on deterioration see. 2. Check up reliability of spring connection between a press disk and the case of a leading part of coupling. Presence of scratches and absence or damage of rivets is not supposed. 3. Check up press a disk on absence of cracks, пригара and deterioration of a surface. Using a steel ruler and an edge щупа, check up неплоскостность a working surface of a press disk. Неплоскост ность a press disk should not exceed 0,2 mm. 4. Check up a condition of a surface of a friction of a flywheel on absence of cracks, пригара and deterioration of a surface. 5. Check up a condition of frictional overlays of a disk of coupling and at presence with them of traces of oil or mechanical damages replace a coupling disk. 6. Measure a thickness of overlays of a disk of coupling. If their thickness of less admissible or if heads of rivets are close to a working surface, replace them or a coupling disk. 7. Check up face palpation of a disk of coupling which on distance of 2,5 mm from external diameter should make no more than 0,8 mm. 8. Check up a condition выжимного the bearing which should rotate easily, in regular intervals and silently and in it should be absent люфт. The working surface of the bearing influencing a press spring should be smooth, without cracks, local corrosion or development (Direction fig. in which the condition выжимного the bearing is necessary to check see). Faulty выжимной the bearing can be defined, without removing it from the car for what it is necessary to press a coupling pedal on the working engine. If by pressing of a pedal of coupling there is an additional noise, means, выжимной the bearing is faulty, and it is necessary to replace it.

Installation

Centering of a disk of coupling, in relation to a leading part of coupling special оправкой 2174

---

The prevention

At installation of a new disk of coupling or a press disk of coupling remove from them anticorrosive protection.

At installation of a disk of coupling watch, that on its frictional overlays even in insignificant quantities oil has not got. Therefore before installation of a disk of coupling wipe an interfaced surface of a flywheel and a surface of a press disk pure rags, and a coupling disk establish clean hands.

PERFORMANCE ORDER

1. Grease шлицы in a nave of a disk of coupling with a thin layer of special greasing on a basis дисульфида molybdenum. 2. Establish a coupling disk on a flywheel, thus acting part of a nave of a disk of coupling should be directed outside, that is to a transmission. 3. Establish a leading part of coupling on a disk, simultaneously establishing it on directing pins. At repeated installation before the removed leading disk of coupling check up that the labels put before removal are combined. 4. Tighten bolts of fastening of a leading part of coupling so that the coupling disk has been pressed, but at the same time could move in the parties. 5. Using special оправку or an old primary shaft of a transmission, centre a disk of coupling concerning a flywheel, fig. Use of adaptations at removal and installation of a disk of coupling see. 6. A centering of a disk of coupling, in relation to a leading part of coupling, it is possible to make before installation of a leading part of coupling special оправкой 2174, fig. the Centering of a disk of coupling, in relation to a leading part of coupling special оправкой 2174 see. 7. After a centering of a disk of coupling gradually and in diagonal sequence tighten bolts of fastening of a leading part of coupling by the moment of 25 Nanometers. 8. Take оправку from a coupling disk. 9. Grease шлицевую a part of a primary shaft of a transmission and directing plug выжимного the bearing with a thin layer of special greasing on a basis дисульфида molybdenum. 10. Establish a transmission.
