Inspect: Examine the flywheel for scoring or excessive wear; resurface or replace if necessary.
Install new clutch components:
- Place the new clutch disc onto the flywheel.
- Align the pressure plate and tighten bolts to the manufacturer’s torque specifications (typically around 18-25 lb-ft; check specific service manual).
Reinstall the transmission: Lift the transmission back into position and secure it with bolts. Reconnect all removed components.

4. Final Assembly

Reinstall driveshaft: Connect the driveshaft back to the transmission and rear axle.
Reconnect battery: Ensure all electrical connectors are plugged back in, then reconnect the battery.
Check fluid levels: Verify and top off the clutch hydraulic fluid if necessary.
