To bleed air from the hydraulic actuator:
- clean the tank and bleeder from dust and dirt;
- check the fluid level in the hydraulic reservoir and add fluid if necessary;
- put on the head of the fitting 9 (pic. 3-3) working cylinder hose and immerse its lower end in a container of hydraulic fluid (30-50 g);
- unscrew fitting 9 by 1/2-3/4 turn, sharply press and slowly release the pedal until air bubbles from the hose stop;
- pressing the pedal, wrap the fitting to the full. Remove the hose and put on the fitting cap.
Pic. 3-3. Slave cylinder and clutch release fork: 1 - clutch release bearing, 2 - ball bearing; 3 - clutch release fork; 4 - pusher; 5 - adjusting nut, 6 - locknut; 7 - withdrawal spring; 8 - body plug; 9 - fitting for pumping; 10 - cylinder body; 11 - sealing ring; 12 - protective cap; 13 - piston; 14 - sealant; 15 - plate; 16 - spring; 17 - support washer; 18 - retaining ring
If, despite prolonged pumping, air bubbles come out of the hose, check the reliability of the fastening of the connections, find out if there are any cracks or leaks on the tubes in the connections with the fittings Air may enter through damaged sealing rings of the main or working cylinders.
When pumping:
- the fluid level in the hydraulic reservoir must be above the opening of the tube connecting the reservoir to the clutch master cylinder;
- the end of the bleed hose must be permanently immersed in the liquid.
After pumping, bring the fluid level in the tank to the lower edge of the filler neck.
