- 1 - Flywheel
The contact surface facing the friction linings must be smooth and free from oil and grease. Make sure that the centering pins are in a secure position.
- 2 - Bolt for flywheel
Be sure to replace. Attention: Clean the splines of the input shaft of the gearbox and, when installing a used clutch disc, the hub. Remove rust.
- without dual mass flywheel: 60 Nm + 90°.
- with dual mass flywheel and bolt length 22.5 mm: 60 Nm + 90°
- with bolt length 43 mm: 60 Nm + 180°
- 3 - Driven clutch disc
Installation position: damping package (springs) must face the pressure plate. The friction linings of the driven disk must be in contact with the flywheel, the inscription «checkpoint side», if present, faces the pressure plate.
4 - Pressure plate. Observe the installation position
- 5 - Bolt 25Nm. Unscrew and wrap in several steps
A/B Colored dots. If present, then the white dot (A) must be on the dual mass flywheel side and the white dot (IN) - pressure disc.
On the models in question, a single-disk dry clutch with a diaphragm spring is installed.
The clutch consists of a basket with a pressure plate, a driven plate, a clutch release bearing and a hydraulic drive.
The clutch basket is bolted to the flywheel, which in turn is mounted on the crankshaft of the engine. Between the pressure plate and the flywheel is the clutch disc, which is pressed against the flywheel by the pressure plate. The driven clutch disc is connected through a spline connection to the input shaft of the gearbox.
When the clutch pedal is depressed hydraulically, the clutch release bearing presses the pressure plate spring. This unloads the pressure plate and the driven plate is no longer pressed against the flywheel. The power connection between the engine and transmission is interrupted.
The clutch of all models with manual transmission has a hydraulic drive. The working fluid is brake fluid, which comes from a common reservoir of brake fluid.
Each time the clutch is engaged and disengaged due to friction, the friction linings of the driven disc are worn. The driven disk is the wearing element of the clutch. Its average service life is over 100,000 km. Wear rate dependent on load (trailer driving) and driving style. The clutch does not require maintenance since it is self-adjusting.
Most engines are equipped two-mass flywheel. Such a flywheel has a spring-damping system that allows you to dampen torsional vibrations that occur during engine operation. In addition, this reduces the noise level at low speeds. The clutch disc with such a flywheel consists of a hub, a driven plate and friction linings. Damping springs not installed.
