Disconnect Components
- Disconnect the linkage between the clutch pedal and the clutch release mechanism. This may involve removing pins, clips, or bolts.
Remove the Transmission
- Depending on the tractor’s design, you may need to remove the transmission to access the clutch assembly. This can involve removing bolts securing the transmission housing.
Remove the Pressure Plate
- Loosen and remove the bolts securing the pressure plate to the flywheel. It’s advisable to loosen the bolts gradually and in a crisscross pattern to release pressure evenly.
Remove the Old Clutch Disc

Install the New Clutch Disc
- Slide the new clutch disc onto the transmission input shaft, ensuring it aligns correctly. Use a clutch alignment tool to center the disc.
Install the Pressure Plate
- Place the pressure plate over the clutch disc and align it with the dowel pins. Tighten the bolts in a crisscross pattern to the specified torque value.
Reassemble Components
- Reconnect the transmission, linkage, and any other components that were removed.
Adjustments
- Adjust the clutch linkage according to the tractor’s service manual. This ensures proper engagement and disengagement of the clutch.
Test the Clutch
- With the tractor safely elevated, start the engine and test the clutch for smooth engagement and disengagement. Check for any unusual noises or issues.
Lower the Tractor
- Carefully lower the tractor back to the ground.
Final Checks
- Double-check all connections, tighten any remaining bolts, and ensure that all components are properly secured.
Always refer to the specific service manual for your tractor model, as procedures can vary.
