Clutch release slave cylinder.
1 - valve plunger, 2 - valve spring, 3 - working cylinder body, 4 - return spring, 5 - piston, 6 - boot, 7 - stem, 8 - pin, 9 - cotter pin, 10 - clutch hydraulic tube.
Withdrawal
1. Disconnect the hydraulic clutch release pipe.
2. Disconnect the slave cylinder rod yoke from the clutch release lever.
3. Turn away two bolts, remove washers and the working cylinder of a drive of deenergizing of coupling.
Disassembly
1. Remove the clutch hydraulic hose, valve plunger, spring, stem and boot.
2. Remove all contaminants from the inner surface of the working cylinder.
3. Remove the piston from the working cylinder using compressed air.
Attention:
- Wrap a rag around the slave cylinder to prevent the piston from flying out during removal and to prevent injury.
- Apply compressed air gradually to prevent spray fluid from splashing into the eyes or onto the skin.
Examination
1. Check the clutch release cylinder for fluid leaks.
2. Check up a casing of the working cylinder on absence of damages.
3. Check the inner surface of the slave cylinder body for rust and damage.
5. Measure the internal diameter of the working cylinder with a bore gauge.
Note: having installed the inside gauge in the working cylinder, measure the diameter in three sections by shifting the inside gauge in the axial direction. Then turn the caliper 90°and repeat the operation. All six values obtained must meet the technical data.
- Rated value: 20.64 mm
6. Measure the outer diameter of the piston with a micrometer and calculate the clearance between the piston and the working cylinder body (the difference between the inner diameter of the working cylinder and the outer diameter of the piston).
If the clearance exceeds the maximum allowable value, then replace the slave cylinder assembly.
- Limit value: 0.15 mm
Assembly
1. Apply brake fluid to the inside of the clutch slave cylinder housing and to the outside of the piston. Install the piston assembly into the slave cylinder body.
- Fluid type: SAE J 1703 brake fluid (DOT3)
2. Install the clutch hydraulic hose, valve plunger, spring, stem, and shroud, and tighten the bypass bolt.
- Torque: 25
Installation
1. Apply grease to the pin. Align the hole in the slave cylinder yoke with the hole in the clutch release lever and install the pin.
- Grease CASMOLY L9508
2. Install the slave cylinder and tighten the two bolts.
- Tightening torque: 15-22 Nm
3. Connect a tube of a hydrodrive of deenergizing of coupling.
- Tightening torque: 12-16 Nm
