In the passenger compartment, disconnect the pusher from the clutch pedal by unscrewing the nut 1 and removing the axle 2 of the pusher with two plastic bushings
Disconnect return spring 5 from the pedal.
Remove cotter pin 3, unscrew nut 4 that fastens the pedal to the axle and remove the pedal assembly with two bushings.
Remove the pedal pad if necessary.
Inspection and troubleshooting of clutch pedal parts
- 1. Bushings must not be mechanically damaged. One-sided bushing wear indicates that there is unacceptable play in the pedal assembly, which in turn affects the full pedal travel.
Replace defective parts.
- 2. If the return spring has lost its elasticity, i.e. the clutch pedal in the free state does not reach the limiter, replace the spring.
- 3. In case of significant wear of the clutch pedal pad pattern, it is recommended to replace it.
Installation
Install the clutch pedal in the reverse order of removal. In this case, it is necessary to lubricate the friction surfaces of the bushings and the axle with a thin layer of graphite lubricant.
Clutch pedal adjustment
- 1. Adjust the pedal stroke by changing the length of the master cylinder pusher.
To do this, disconnect the pusher from the pedal, loosen the nut 1 of the pusher adjusting unit and, turning the eye 2 in the desired direction, achieve the desired result.
Then tighten the nut and connect the pushrod to the pedal.
- 2. The total travel of the clutch pedal should be between 145-160 mm.
- 3. Pedal free play is not adjustable.
Bleeding the clutch hydraulic system
- 1. Fill the reservoir of the clutch master cylinder with fresh brake fluid to a level of 15-20 mm below the upper edge of the reservoir.
- 2. Remove the protective cap from the slave cylinder valve.
- 3. Attach the bleed hose to the valve. Dip the other end of the hose into a container with a small amount of brake fluid so that it is in the fluid.
- 4. Press the clutch pedal several times and keep the clutch pedal depressed.
- 5. Open the bleed valve to bleed air from the system. The presence of air in the system is determined by the appearance of bubbles in the container.
- 6. Close the bleed valve.
- 7. Repeat the steps described in points 4-6 until no more air bubbles appear in the container.
- 8. Remove the hose from the bleed valve and put on the cap.
- 9. Add brake fluid to the master cylinder reservoir to a level 20 mm below the upper edge of the reservoir.
- 10. The absence of air in the system can be determined by the amount of movement of the outer end of the clutch release fork: when the clutch pedal is fully depressed, it should be at least 14 mm.
If you need to completely remove the pedal assembly:
Remove the instrument panel (GAZ-3110 instrument panel removal).
Disconnect the two wires of the brake light switch.
With a 13 head with an extension, we unscrew the two nuts located behind the steering column bracket (do not confuse them with the nuts securing the bracket itself).
We take out the cotter pin of the brake pedal pusher axis and, holding the bolt with a 17 key, unscrew the nut with a 19 key. We take out the bolt.
In the same way, we take out the axle of the clutch pedal pusher (it does not cotter).
Plastic bushings are inserted into the holes of the pushers of the clutch and brake pedals. When assembling, lubricate and reinstall them.
Using a 13 key, unscrew 4 nuts securing the bracket to the panel and remove the pedal assembly.
Install the pedal assembly in reverse order.
