Flywheel, basket and clutch disc
1 — Flywheel. The surface adjacent to the friction linings must be free of oil and grease and free of burrs. Ensure that the centering pins are securely fastened
2 — Clutch slave disc. The installation position should not be changed.
3 - Pressure plate
4 - Hexagon socket head cap screw, 25 Nm. Loosen and tighten in several steps crosswise
Attention! Clean the teeth of the splined connection of the primary shaft of the gearbox and the hub, remove rust
The models in question are equipped with a single-disc dry clutch with a diaphragm spring.
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 secured to the engine crankshaft. Between the pressure plate and the flywheel is the driven clutch disc, which is pressed against the flywheel by the pressure plate. The driven clutch disc is centered through a splined connection with the primary shaft of the gearbox.
When the clutch pedal is pressed, the clutch release bearing presses the pressure plate spring using the hydraulic drive. This relieves the pressure plate and the driven disk is no longer pressed against the flywheel. The power connection between the engine and transmission is interrupted.
The clutch of all models has a hydraulic clutch drive. The working fluid on models with a manual transmission is brake fluid, which comes from a common brake fluid reservoir. On models with an automated transmission, the hydraulic clutch circuit is part of the hydraulic system of the gearbox control drive.
Each time the clutch is engaged and disengaged, friction wears out the friction linings of the driven disk. The driven disk is a wearing element of the clutch. Its average service life is over 100,000 km. The wear rate depends on the load (driving with a trailer) and driving style. The clutch does not require maintenance, as it is self-adjusting.
The engines are equipped with a dual-mass flywheel. Such a flywheel has a spring-damping system that allows 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 are not installed.
