Removal and installation the clutch slave cylinder assembly with release bearing (Opel Astra G)

Remember that dust generated during wear of the clutch slave disk friction linings may contain asbestos, which is harmful to health. Do not blow off dust with compressed air and try not to inhale it. Do not use petroleum-based solvents to wipe clutch components — use only special brake cleaners or pure methyl alcohol. Place used rags in a hermetically sealed container.

Removal

1. To remove the slave cylinder assembly with the release bearing, it is necessary to dismantle the gearbox (see Chapter Manual gearbox), or remove the power unit.

2. Thoroughly wipe the outside of the cylinder, then loosen the union nut and disconnect the hydraulic line from the cylinder, immediately wipe up any spilled hydraulic fluid with a rag.

3. Unscrew the three mounting bolts and remove the cylinder from the input shaft. Remove the sealing ring installed between the cylinder and the manual transmission housing - the ring must be replaced without fail. Take precautions against dirt getting into the box.

4. A failed actuator cannot be repaired. If hydraulic fluid leaks develop, replace the cylinder assembly.

Installation

1. Make sure that the mating surfaces of the cylinder and the manual transmission housing are absolutely clean and dry. Place a new sealing ring in the receiving groove on the transmission housing.

2. Lubricate the cylinder with clean transmission oil, place it on the shaft journal and press it against the gearbox housing. Check the fit of the sealing ring in the receiving groove, then screw in the mounting bolts and tighten them to the required force.

3. Connect the hydraulic line to the cylinder and tighten the union nut to the required torque.

4. Install the gearbox onto the engine (see Chapter Manual gearbox).

5. Bleed the hydraulic system (see Bleeding air from the hydraulic circuit of the clutch release drive).
