11. How do you deal with a damaged flywheel?

    • Answer: If the flywheel is damaged beyond repair (e.g., cracks, excessive wear), it must be replaced. I'd assess the damage and determine if resurfacing is an option or if a complete replacement is necessary. The replacement process requires precision to ensure proper balance and function.

12. How do you test a clutch master cylinder?

    • Answer: I'd check for leaks visually and check the fluid level. I would also test the pedal feel for firmness; a soft pedal indicates a problem with the master cylinder. A pressure test can be used to measure the hydraulic pressure in the system. Low pressure would confirm master cylinder failure.

13. How do you test a clutch slave cylinder?

    • Answer: Similar to the master cylinder, I’d check for leaks. I would also check for proper movement of the clutch fork and the release bearing when operating the clutch pedal. A visual inspection for leaks and proper operation during pedal depression will help determine its functionality.

14. How important is torque specification when working on a clutch?

    • Answer: Torque specifications are crucial. Incorrect torque can lead to premature failure of components, damage to threads, or even a catastrophic failure. I always use a torque wrench to tighten bolts and nuts to the manufacturer's recommended specifications.
