Removal and installation

1. Remove liquid from a coupling hydraulic actuator tank.
2. Lift a car front.
3. Disconnect a coupling hydraulic actuator hose, for this purpose it is required to shoot the cylinder with parts of cars.
4. Turn off nuts and remove the cylinder. 1. Hydraulic actuator hose
2. Nuts
3. The union for removal of air
5. Check wear of a plastic pusher of a head and the lever of a pusher. The lever as a rule wears out only in deepening under a pusher. The increased 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 detection of a leak through consolidation of a pusher replace the cylinder. When replacing consider that on models with a usual flywheel the cylinder with an internal diameter of 20,64 mm, and on models with a dual flywheel – with an internal diameter of 22,2 mm is installed.
7. Installation is carried out upside-down. Grease a pusher head with molybdenic lubricant and be convinced that the pusher came into deepening on the lever. Fill in liquid and remove air.
