A flywheel bolt clamps the flywheel to the crankshaft flange. This lets engine torque pass through the flywheel to the clutch. The catalog lists this part as a Clutch Flywheel Bolt, and ATP describes it as a Manual Transmission Flywheel Bolt. Both names refer to the same part.
Signs a flywheel bolt may need replacing include damaged or stretched threads found during clutch or flywheel service. A knock or vibration from the bellhousing area can also be a sign, but it can have other causes, so diagnose the cause before replacing parts. Consult the vehicle service information for the correct torque specification and for whether the original bolts may be reused.
