Excessive clutch slip can cause heat distortion of which components?

• A. Flywheel and pressure plate.
• B. Release bearing.
• C. Transmission case.
• D. Input shaft.

Answer: (A)

When the clutch slips, there’s friction between the clutch disc and the flywheel/pressure plate while torque is being transmitted. That friction turns into heat, and the heat is mainly absorbed by the contact surfaces of the flywheel and the pressure plate. If slipping is excessive or prolonged, those surfaces can warp or distort from the uneven heating, leading to uneven engagement and other clutch problems.

The release bearing is involved in disengagement and can overheat, but distortion isn’t the typical consequence for it. The transmission case and input shaft aren’t the primary surfaces that heat up and distort from clutch slip, since they aren’t the friction faces in contact during slipping.
