- Carefully lower the transmission from the vehicle.
Remove the old clutch assembly:
- Unbolt the pressure plate from the flywheel and carefully remove it.
- Remove the clutch disc from the flywheel.
Install the new clutch assembly:
- Position the new clutch disc onto the flywheel, ensuring alignment.
- Secure the pressure plate over the clutch disc and torque bolts to manufacturer specifications.
Reinstall the transmission:
- Align the transmission with the engine and secure it with bolts.
- Reattach electrical connections and linkages.

4. Refill and Bleed Clutch System
