• Inspect the flywheel surface for heat checking, cracks, or wear before reinstallation
• Clean crankshaft mounting surface thoroughly before installing new bolts
  

 

Frequently Asked Questions

Q: How many flywheel bolts do I need for my engine?
A: 8 bolts per flywheel. 

Q: Can I reuse my old flywheel bolts?
A: No. These are torque-to-yield (TTY) bolts that permanently stretch during installation to achieve proper clamping force. Reusing TTY bolts can result in insufficient clamping, leading to flywheel detachment and catastrophic engine damage. Always replace with new OEM bolts during clutch service.

Q: What is the correct torque specification?
A: Toyota specifies 65 ft-lbs (88 Nm) for this flywheel bolt across all compatible applications. Use a quality torque wrench and tighten in a star pattern to ensure even clamping pressure across the flywheel surface.
