If a clutch disc is worn and replacement occurs, which components should be checked for condition or warping to ensure proper engagement?

• A. Technician A only.
• B. Technician B only.
• C. Both technicians.
• D. Neither technician.

Answer: (C)

Proper clutch engagement requires true, flat mating surfaces between the flywheel and the pressure plate. If the flywheel surface is warped or the pressure plate surface is warped or worn, the new clutch disc won’t sit evenly, leading to grabbing, slipping, or uneven engagement. That’s why both surfaces should be checked when a clutch disc is replaced. If either surface shows warping or wear beyond spec, correct it before finishing installation—typically by resurfacing or replacing the flywheel and inspecting/servicing the pressure plate. Also, inspecting related parts like the pilot bearing and release bearing helps ensure smooth clutch operation. In short, you can’t rely on a single inspection to guarantee proper engagement; both surfaces must be evaluated.
