Pic. 3-5. Master Cylinder Details:
1 - cylinder;
2 - protective cap;
3 - retaining ring;
4 - pusher piston;
5 - sealing ring;
6 - piston of the main cylinder;
7 - sealing ring;
8 - return spring;
9 - sealing gasket;
10 - fitting;
11 - lock washer;
12 - gasket.
The cylinder mirror and the outer surface of the piston must not be damaged or scratched. Check the condition of the piston spring and replace it if it has lost elasticity.
Replace the piston collar and all sealing elements. Check the protective boot on the rear end of the cylinder and if the boot is damaged, replace it with a new one. Carefully clean and flush parts with brake fluid before reassembly. Avoid contact with mineral oil, gasoline, kerosene or diesel fuel, as these substances swell rubber seals.
After checking all the parts, assemble the master cylinder in the reverse order of disassembly, while:
- apply a thin layer of DT-1 grease on the surfaces of the piston in contact with the cylinder, support sleeve and pusher;
- lubricate all other parts of the cylinder with brake fluid.
Working cylinder. Remove protective rubber boot 6 (pic. 3-6) together with the pusher 5, then remove the retaining ring 7. This will allow you to remove the piston 8, the piston collar 9, the spring cup 10 and the spring 11.
Pic. 3-6. Clutch Release Cylinder Parts (working cylinder):
1 - body;
2 - transport plug;
3 - fitting;
4 - fitting cap;
5 - pusher of the clutch release fork;
6 - protective cover;
7 - retaining ring;
8 - piston;
9 - piston cuff;
10 - spring cup;
11 - spring.
After disassembly, carefully wash and inspect all parts as indicated for the master cylinder. It is not allowed to install a deformed pusher.
After checking, proceed with the assembly (reverse order of disassembly), wherein:
- apply a thin layer of DT-1 grease on the surfaces of the piston in contact with the cylinder and pusher;
- lubricate all other parts of the cylinder with brake fluid.
