What issue can arise from excessive flywheel face turnout?

Excessive flywheel face turnout can lead to uneven pressure distribution on the clutch disc, which is crucial for the effective operation of the vehicle's drivetrain. The flywheel serves as a critical component that interacts with the clutch system to engage and disengage power from the engine to the transmission. When the flywheel face is turned down too much, it can alter the flatness or surface area contact of the clutch disc against the flywheel.

This irregular contact can cause the clutch to engage unevenly, leading to increased wear on the clutch disc, potential slipping, or grabbing, which further affects the vehicle's ability to transmit power efficiently. Maintaining the proper specifications of the flywheel ensures that the clutch functions correctly, providing smooth operation and longevity for both the clutch and related components. In automotive maintenance, it's essential to keep flywheel turnout within specified limits to prevent these issues from arising.
