Using the tools for removal and installation of clutch | 3067 - a device for fixing the flywheel from turning 3176 - Tool for centering clutch |
A warning  When the clutch is formed dust which contains asbestos, unhealthy, so when cleaning the clutch does not use compressed air and do not inhale the dust. Purification of the clutch parts from dust produce using the brake fluid, or methyl alcohol. After cleaning the coupling parts with the use of methyl alcohol or eat a brake liquid wipe details dry.
Withdrawal
| PERFORMANCE ORDER | | 1. Remove the gearbox. | | 2. Mark the position of leading knot of coupling in relation to the flywheel, using a marker or paint. | 3. Using the special tool VW-3067 or the screwdriver, the teeth of the flywheel block a flywheel from turning,
see. Fig. Using the tools for removal and installation of clutch) | | 4. Gradually in diagonal sequence to loosen the bolts leading knot of coupling, turning each bolt on half of turn until until the action of a spring and bolts can be unscrewed by hand. | | 5. Remove the pressure plate, thus support the clutch plate so that it does not fall. | | 6. Clean the flywheel with gasoline. |

Check
Places checking pressure diaphragm spring for wear
The direction in which you need to check the status of the release bearing
| PERFORMANCE ORDER | | 1. Check the pressure plate. Traces generate at the ends of the compression spring must be not more than 0.3 mm, see. Fig. Designated checking pressure diaphragm spring wear. | | 2. Check the spring connection between the pressure plate and the housing leading part of coupling. It is not allowed for scratches and missing or damaged rivets. |  | 3. Check the pressure plate for cracks, metal penetration and wear surfaces. Using a steel ruler and the blade of the probe, check the flatness of the working surface of a press disk. Of non-planar pressure plate should not exceed 0.2 mm. | | 4. Check the condition of the friction surface of the flywheel for cracks, metal penetration and wear surfaces. | | 5. Check the condition of the friction linings and the clutch disc in the presence with them of traces of oil or mechanical damages replace a coupling disk. | | 6. Measure the thickness clutch. If the thickness of less admissible or if heads of rivets are close to the work surface, or replace the clutch disc. |  | 7. Check the clutch disc runout, which is at a distance of 2.5 mm from the outer diameter shall be not more than 0.8 mm. | 8. Check the release bearing which should rotate easily, smoothly and quietly and it should no longer play. The working surface of the bearing influencing a press spring should be smooth, without cracks, local corrosion or development (see. Fig. The direction in which you need to check the status of the release bearing).
Defective release bearing can be determined without removing it from the car, which requires the engine is running, press the clutch pedal. If the clutch pedal is pressed, an additional noise, means the release bearing is defective and must be replaced. |

Setting
Centring the clutch disc with respect to the leading part of coupling special mandrel 2174
A warning When installing a new clutch and pressure plate coupling remove from them anticorrosive protection. When installing the clutch, make sure that its friction linings, even in small amounts has not got oil. Therefore, before installing the clutch disc, wipe the mating surface of the flywheel and pressure plate surface with a clean cloth and place the clutch disc with clean hands.
| PERFORMANCE ORDER | | 1. Coat the spline on the clutch disc with a thin layer of special lubricants based on molybdenum disulfide. | | 2. Install the clutch disc on the flywheel, and the protruding portion of the hub clutch should be directed to the outside, that is, to the gearbox. | | 3. Set the leading part of coupling to the disk at the same time setting it on the guide pins. When reinstalling the previously recorded master clutch disc, check that the labels put before removal combined. | | 4. Tighten the leading part of the clutch so that the clutch plate has been pressed, but at the same time, he could still move sideways. | | 5. Using a special holder or old gearbox output shaft, align the clutch disc onto the flywheel, see. Fig. Using the tools for removal and installation of clutch disc. | | 6. Centering disc clutch, relative to the leading portion of the clutch can be performed prior to installing a leading part of the special coupling mandrel 2174, see. Fig. Centering disc clutch, relative to the leading portion of the mandrel 2174 special clutch. | | 7. After centering the clutch gradually and in diagonal sequence tighten bolts of fastening of a leading part of coupling 25 Nm. | | 8. Remove the mandrel from the clutch disc. | | 9. Grease the splined shaft of the primary transmission and the release bearing guide sleeve with a thin layer of special lubricants based on molybdenum disulfide. | | 10. Install the transmission. |
