Removal and installation

1. Remove liquid from a tank of a hydraulic actuator of coupling.
2. Lift a car front.
3. Disconnect a hose of a hydraulic actuator of coupling, for this purpose on a part of cars it is required to remove the cylinder.
4. Unscrew nuts and remove the cylinder. 1. Hydraulic actuator hose
2. Nuts
3. The union for air removal
5. Check wear plastic heads of a pusher and the pusher lever. The lever as a rule wears out only in deepening under a pusher. The strengthened wear on each side and on the lever out of deepening indicates heads of a pusher violation of axial provision of a pusher.
6. At leak detection through pusher consolidation the cylinder replace. At replacement consider that on models with a usual flywheel the cylinder with internal diameter of 20,64 mm, and on models with a dual flywheel – with internal diameter of 22,2 mm is established.
7. Installation is carried out upside-down. Grease a pusher head with molybdenic greasing and be convinced that the pusher came into deepening on the lever. Fill in liquid and remove air.
