Withdrawal
1. Disconnect the hydraulic tube from the working cylinder.
Examination
1. Clean the dismantled parts in solvent and blow out all parts and passages with compressed air.
2. Check the clutch slave cylinder and boots for damage.
Disassembly
1. Disconnect the connecting hose from the cylinder and remove the valve plate, spring, pusher and protective cover.
2. Remove dirt around the working cylinder bore for the piston.
3. Remove the piston and collar by blowing compressed air through the hydraulic tube connection port.
Attention!
- 1. Cover the opening of the working cylinder with a clean rag to catch the piston pushed out by compressed air.
- 2. Increase the air pressure gradually to prevent the release of brake fluid and its contact with the eyes or skin.
Examination
1. Check the clutch slave cylinder and boots for damage.
2. Measure the inside diameter of the clutch master cylinder. If the clearance between the piston and cylinder is greater than the allowable value, replace the master cylinder and/or piston assembly. Measurement of the inner diameter of the clutch master cylinder is carried out in three sections (at the base, center and top) in two perpendicular directions.
Gap: 0.15mm.
Assembly
1. Lubricate the piston and cylinder bore with clutch fluid before assembling, and install the piston assembly.
Fluid: DOT-3 or DOT-4 brake fluid.
2. Install valve plate, tappet and boot.
