- Check clutch linkage adjustment. Clutch linkage should be adjusted when new clutch installed into vehicle, also linkage should be re-adjusted after first 700 miles and after that every 10,000 miles.
- The hydraulics of the car could be faulty or have air in the lines (bleed clutch). Check clutch master cylinder, slave cylinder for any signs of leaking or failure. Hydraulics could have internal leaks as well which can cause improper operation. Check hydraulic lines for cracks or over expansion. Due to the higher loads from performance plates, the O.E. rubber hydraulics hoses can expand causing not enough fluid to be moved to actuate the clutch.
- Clutch fork can be bent or broken. Pivot ball can be damaged (smashed) causing insufficient actuation.
- Improper or damaged release bearing.
- Flywheel was not re-surfaced or has incorrect flywheel step.
- Too light of transmission lubricant or lubricant level low.
- Clutch disc is hanging up on the input shaft. Check input shaft for any burrs and make sure disc can move smoothly on splines. Also hanging up can be caused from not using grease on the splines which results in a dry spline which causes friction between the parts.
- Cable linkage vehicles the cable could be stretched from overuse or clutch quadrant cracked or broken.
- Clutch disc installed improperly (backwards)
- Clutch disc hitting flywheel bolts
- Input shaft bent causing clutch disc runout
- Pressure plate has defective or damaged drive straps.
- Clutch disc or pressure plate assembly bent or damaged.
I cannot get my vehicle out or into gear (no release) or I am having problems in high rpms my clutch will not disengage (high rpm lockout).
