Throw-out Bearing Replacement
See also our Throw-out Bearing Discussion
(questions and answers).
Note: Both the Bentley Manual and the Haynes Manual call this a Clutch Release Bearing. The bearing is situated at the rear of the transmission. It is fastened to the clutch operating shaft by two retaining springs. It is supported by a central guide sleeve.
- Remove the engine from the car (see the Engine Removal and Installation procedure).
- Remove the clutch pressure plate and disk from the flywheel (see the Clutch Removal and Installation procedure).
- To lubricate the throw-out bearing, roughen the surface of the plastic facing ring on the throw-out bearing with coarse emery cloth. Then rub in a small amount of molybdenum grease. Do this routinely whenever the engine is removed.
- To remove the throw-out bearing, pry the retaining springs off with a screwdriver. Hold a rag over the springs to prevent them from flying off and becoming lost when tension is relieved.
- Check the general condition of the bearing. Hand-turn it; it should not feel gritty or be difficult to turn. Make sure the plastic facing ring has not worn through. If necessary, replace the bearing.
Note: Never wash the bearing in solvent since this will remove the factory-installed lubricant.
- Lightly lubricate the operating shaft bushings with multipurpose grease. Lightly lubricate the guide sleeve with molybdenum grease.
- Install the throw-out bearing and the retaining springs. Make certain that the hooked ends of the springs engage behind the levers on the operating shaft. Replace loose-fitting retaining springs.
- After you install the engine, check the clutch pedal freeplay and adjust as necessary (10-20mm).
- While you're there, check the condition of the rubber sleeve and the position of the flexible guide tube. If cracked or loose fitting, replace. The flexible guide tube should sag 25 to 45 mm. This sag can be adjusted by adding or subtracting spacer washers.
Note: Excessive sag in the flexible guide tube will cause the cable to bind, creating noise, difficult clutch pedal operation, or even cable breakage. If the sag is inadequate, there will be insufficient preload on the cable. This can cause poor clutch pedal feel and accelerated wear.
