Do you HAVE to replace the flywheel if clutch?

No, it is not always necessary to replace the flywheel when replacing the clutch. The flywheel can be inspected and if it is still in good condition, it can be reused.

The flywheel is a heavy wheel that stores rotational energy and helps to smooth out the delivery of power from the engine to the transmission.

Here are some cases where the flywheel may need to be replaced as part of a clutch replacement:

• The flywheel is damaged or cracked.

• The flywheel has excessive wear or grooves on its surface.

• The flywheel is warped or distorted.

• The flywheel's teeth (for attaching to the starter ring gear) are damaged or worn.

If any of these conditions are present, it's advisable to replace the flywheel to ensure proper function, balance, and durability of the drivetrain. Consult with a trained mechanic or clutch specialist if you're unsure if replacing the flywheel is necessary during a clutch replacement.
