Professional installation required. Proper procedure is critical for safety and performance:

1. Disconnect battery – Disconnect the negative battery cable before beginning work
2. Remove the transmission – Safely remove the transmission and clutch assembly
3. Remove the old flywheel – Mark the position if required, remove the flywheel mounting bolts
4. Inspect the crankshaft flange – Check for wear, burrs, or damage to the crankshaft mounting surface
5. Check the pilot bearing – Inspect and replace the pilot bearing/bushing as needed
6. Clean the crankshaft – Thoroughly clean the crankshaft flange and bolt holes
7. Inspect new flywheel – Verify all dimensions and check for damage before installation
8. Apply thread locker – Apply manufacturer-recommended thread locker to the flywheel bolts
9. Install new flywheel – Position the new flywheel on the crankshaft flange
10. Install and torque bolts – Tighten flywheel bolts in a star/crisscross pattern to the specified torque
11. Check runout – Use a dial indicator to check flywheel face runout (must be within specification)
12. Install new clutch – Install the new clutch disc, pressure plate, and pilot bearing
13. Reinstall transmission – Reinstall the transmission and all connected components
14. Check starter engagement – Verify proper starter motor engagement with the ring gear
15. Reconnect battery – Reconnect the battery and test starter engagement
16. Test drive – Road-test the vehicle to verify clutch operation and vibration-free performance
