3. Installation Guidelines
Installation of the engine sheave typically involves removing the old sheave and mounting the new one onto the engine shaft. This process requires mechanical aptitude and appropriate tools. If you are unsure about any step, consult a qualified service technician.
- Safety First: Ensure the equipment is turned off, the engine is cool, and the spark plug wire is disconnected to prevent accidental starting.
- Access the Sheave: Depending on your equipment model, you may need to remove covers or other components to gain access to the engine sheave.
- Remove Old Sheave: Loosen any retaining bolts or nuts. A puller tool may be required to safely remove a seized sheave from the shaft.
- Inspect Shaft: Clean the engine shaft thoroughly and inspect for any damage or wear.
- Install New Sheave: Carefully slide the new Exmark 135-6571 sheave onto the engine shaft, ensuring proper alignment with the keyway (if applicable).
- Secure Sheave: Tighten retaining bolts or nuts to the manufacturer's specified torque settings. Refer to your equipment's service manual for exact torque values.
- Reassemble: Reinstall any covers or components that were removed.
- Belt Installation: Ensure all belts are correctly routed and tensioned according to your equipment's manual.

4. Maintenance and Inspection
Regular inspection and maintenance of the engine sheave and associated components are essential for prolonging the life of your equipment and ensuring safe operation.
- Visual Inspection: Periodically check the sheave for signs of wear, cracks, chips, or excessive rust. The grooves should be smooth and free of debris.
- Belt Condition: Inspect the drive belts for fraying, cracking, glazing, or stretching. Worn belts can cause slippage and accelerate sheave wear.
- Bearing Check: If the sheave has an integrated bearing, check for any play or roughness when rotating.
- Cleanliness: Keep the sheave and surrounding area free of grass clippings, dirt, and other debris that can interfere with belt operation or cause premature wear.
- Alignment: Ensure the sheave remains properly aligned with other pulleys in the system. Misalignment can lead to rapid belt and sheave wear.
5. Troubleshooting Common Issues
If you experience problems related to the power transmission system, consider the following:
- Excessive Noise: Squealing or grinding noises may indicate a worn sheave, a loose or worn belt, or a failing bearing.
- Loss of Power/Slippage: If the mower deck or drive wheels are not engaging properly, or if there's a noticeable loss of power, check for a stretched or damaged belt, or a worn sheave groove.
- Vibration: Unusual vibrations could be caused by an unbalanced or damaged sheave.
- Belt Ejection: Belts frequently coming off the sheave can be a sign of sheave misalignment, worn sheave flanges, or an incorrect belt size.
Always address these issues promptly to prevent further damage to your equipment.
