Clutch Cylinder Bench Bleeding

Clutch Cylinder Bench Bleeding





Material

1. CAUTION: So as not to trap air in the clutch hydraulic system, fill any disconnected component (such as master cylinder, slave cylinder) with the specified brake fluid before connecting it.

Support the clutch hydraulic system components so that the reservoir/master cylinder assembly is above the slave cylinder. Position the line so that there are no high points that could trap air.





2. Fill the clutch master cylinder reservoir to the full line with brake fluid.





3. CAUTION: Do not allow the clutch master cylinder reservoir to run dry.

Purge the air from the clutch hydraulic system.
^ Push the push rod slowly into the slave cylinder until it bottoms out the piston. Hold the push rod in this position for five to ten seconds to allow all trapped air to rise through the system. Look for air bubbles in the fluid in the clutch hydraulic reservoir. Very slowly, so that air is not drawn back into the slave cylinder, release the pushrod (the spring in the slave cylinder will force the piston outward). Wait five to ten seconds for the air bubbles to rise. Repeat this process five to ten times to make sure that all air purged from the system.





4. Verify that the fluid level in the reservoir is correct and install the cap.
