If a flywheel is hard spotted and grooved, what is the best course of action?

If a flywheel is hard spotted and grooved, checking for cracks before reusing it is a vital step in the diagnostic and repair process. Hard spots and grooves can indicate excessive wear or overheating, which may lead to stress fractures that compromise the integrity of the flywheel.

By examining the flywheel carefully for cracks, a technician can determine whether it is structurally sound enough for continued use. This inspection helps ensure safety and performance, as any cracks that are not addressed could lead to failure during engine operation.

If the flywheel passes the crack inspection, it might be suitable for further machining or resurfacing. However, if cracks are found, it is critical to replace the flywheel to avoid catastrophic failure. This thorough approach ensures that the flywheel will perform effectively in the vehicle and prevents future issues.
