To bleed air from the hydraulic actuator:
- clean tank 4 (pic. 3-2) hydraulic clutch and fitting 14 of the working cylinder for pumping from dust and dirt;
- check the fluid level in the hydraulic reservoir and add fluid if necessary;
- install a hose on fitting 14 of the working cylinder and immerse its lower end in a vessel with hydraulic fluid (30-50 g);
- unscrew fitting 14 by ½-3/4 turn, sharply press and slowly release the clutch pedal until air bubbles from the hose stop (Check the fluid level in the reservoir and top up if necessary);
- having pressed a pedal, wrap up the union 14 to the full. Remove a hose and put on a cap of the union.
Pic. 3-2. Clutch drive:
1 - main cylinder;
2 - hose connecting the main cylinder and tank;
3 - tank fastening bracket;
4 - clutch hydraulic reservoir;
5 - hose clamp;
6 - clutch drive hose;
7 - gasket;
8 - clutch slave cylinder;
9 - fork support;
10 - clutch release fork;
11 - plug cover;
12 - thrust plate;
13 - bracket of the working cylinder;
14 - bleed valve;
15 - clutch pedal;
16 - bracket;
17 - clutch drive tube.
If, despite prolonged pumping, air bubbles come out of the hose, check the tightness of the fastening of the connections, find out if there are any cracks or leaks on the tubes in the connections with the fittings. It is possible for air to enter through damaged sealing elements of the main or working cylinders.
When pumping:
- the end of the pumping hose must be constantly immersed in liquid;
- after pumping, bring the fluid level in the tank to the upper mark on its body.
