Professional installation required. Proper clutch system service is critical:

1. Disconnect battery - Disconnect the negative battery cable before beginning work
2. Remove the transmission - Safely remove the transmission assembly from the vehicle
3. Remove the old pressure plate - Unbolt and remove the old pressure plate and clutch disc
4. Inspect the flywheel - Check the flywheel friction surface for wear, scoring, or heat damage
5. Resurface or replace the flywheel - Refinish the flywheel surface or replace if necessary
6. Inspect the release bearing - Check and replace the release bearing if worn
7. Clean thoroughly - Clean the flywheel and pressure plate mounting surfaces
8. Use a clutch alignment tool - Insert the alignment tool through the disc and pilot bearing to center the disc
9. Position the new disc and pressure plate - Place the new disc on the flywheel, then install the new pressure plate
10. Install and torque bolts - Tighten the pressure plate bolts evenly in a crisscross pattern to manufacturer specification
11. Remove the alignment tool - Verify the disc is centered and remove the alignment tool
12. Install new release bearing - Install a new release bearing in the transmission bell housing
