Professional mechanic or transmission specialist installation is strongly recommended:

1. Ensure vehicle is safely supported - Use appropriate jack stands or a lift
2. Disconnect battery - Always disconnect the negative terminal before working
3. Remove the transmission - Support the transmission and remove it from vehicle
4. Remove old clutch assembly - Unbolt pressure plate from flywheel in criss-cross pattern
5. Inspect the flywheel - Check for cracks, hot spots, scoring, or wear
6. Inspect release bearing and pilot bearing - Replace if worn or noisy
7. Clean flywheel surface - Remove all oil, grease, and debris
8. Install new clutch disc - Position with proper orientation (usually "flywheel side" marked)
9. Align clutch disc - Insert clutch alignment tool through disc into pilot bearing
10. Install new pressure plate - Position over disc and align with flywheel dowel pins
11. Install mounting bolts - Hand-start all bolts; tighten in criss-cross pattern to torque specs
12. Remove alignment tool - Carefully withdraw from clutch assembly
13. Install release bearing - Install new bearing on release fork or input shaft retainer
14. Reinstall transmission - Carefully reinstall and secure all mounting bolts
15. Check clutch operation - Verify proper clutch pedal feel and release function
16. Road test - Test drive to verify smooth engagement, no slipping, and proper shifting
