VAZ vehicles use a 2103 clutch with a friction lining width of 29 mm.
On VAZ-2104 and VAZ-2105 cars, a clutch with a release fork is installed, in which the locking spring has a round cross-section instead of the flat one used on other models. Both types of forks are interchangeable.
The clutch has a hydraulic drive. It consists of a leading and a driven part. The leading part of the clutch is made as a separate unit, which is attached to the flywheel 6 (Fig. 110) with bolts 8. It includes: the clutch casing 18, the pressure plate 4 and the pressure spring 2. The driven part of the clutch is the driven disk 5, located between the flywheel and the pressure plate. Two friction linings are riveted to the driven disk, and the disk itself is connected to its hub through elements of the torsional vibration damper (damper).
