- Sheave Removal: Loosen and remove any fasteners securing the old sheave and shaft assembly. Carefully extract the old component.

5. Operating Considerations
Once installed, the sheave with shaft operates as an integral part of your mower's drive system. Proper installation ensures smooth and efficient power transfer. No specific operating procedures are required for the sheave itself beyond ensuring it is correctly installed and maintained.
6. Maintenance
Regular inspection of the sheave with shaft is recommended as part of your mower's overall maintenance schedule. Look for the following:
- Wear: Check for excessive wear on the sheave grooves where the belt rides. Worn grooves can lead to belt slippage and premature belt failure.
- Damage: Inspect for cracks, bends, or other physical damage to the sheave or shaft.
- Bearing Condition: If the sheave includes a bearing, check for smooth rotation and listen for any grinding or unusual noises. A seized or noisy bearing indicates a need for replacement.
- Fastener Tightness: Ensure all mounting bolts and fasteners are securely tightened to prevent movement or vibration.
Replace the sheave with shaft if any significant wear or damage is observed to maintain optimal mower performance and safety.
7. Troubleshooting
If you experience issues after installing or during the operation of your mower, consider the following:
- Belt Slippage: If the belt is slipping on the sheave, check for proper belt tension, wear in the sheave grooves, or incorrect belt type.
- Unusual Noise: Grinding, squealing, or rattling noises from the sheave area may indicate a worn bearing, loose fasteners, or interference with other components.
- Vibration: Excessive vibration could be caused by an unbalanced or damaged sheave, or improper installation.
Always refer to your mower's service manual for specific troubleshooting guides. If the problem persists, contact an authorized Exmark service center.
