1. Ensure vehicle is safely supported - Use appropriate jack stands or a lift to support the vehicle
2. Disconnect battery - Always disconnect the negative terminal before working
3. Remove the transmission - Support the transmission and remove it from the vehicle
4. Remove the old clutch assembly - Unbolt the pressure plate from the flywheel in a criss-cross pattern; remove the pressure plate and clutch disc
5. Inspect the flywheel - Check for cracks, hot spots, scoring, or wear; resurface or replace if necessary
6. Inspect the release bearing and pilot bearing - Replace if worn or noisy
7. Clean the flywheel surface - Remove all oil, grease, and debris from the flywheel friction surface
8. Install the new clutch disc - Position the clutch disc against the flywheel with the proper orientation
9. Align the clutch disc - Insert a clutch alignment tool through the disc and into the pilot bearing
10. Install the new pressure plate - Position the pressure plate over the disc and align with flywheel dowel pins
11. Install mounting bolts - Hand-start all bolts; tighten in a criss-cross pattern to manufacturer torque specifications
12. Remove the alignment tool - Carefully withdraw the alignment tool from the clutch assembly
13. Install the release bearing - Install the new release bearing on the release fork or input shaft retainer
14. Reinstall the transmission - Carefully reinstall the transmission 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 gear shifting

• Material Verification: Confirms cover and diaphragm spring materials meet ISUZU strength and durability specifications
• Dimensional Inspection: Cover diameter, bolt hole pattern, and friction surface dimensions verified within OEM tolerances
• Diaphragm Spring Testing: Spring load and release characteristics tested to ensure consistent clamping force
• Dynamic Balancing: Each assembly balanced to ensure smooth, vibration-free operation
• Friction Surface Inspection: Precision-ground surface checked for flatness and finish
• Visual Inspection: 100% checked for cracks, porosity, or assembly defects
