Step 3: Loosening the Pulley

Once you have access to the pulley, use the wrench to loosen the bolts holding the pulley in place. Turn the bolts counter-clockwise until they are loose enough to remove with your hands. If the bolts are rusted or stuck, apply some penetrating oil and let it sit for a few minutes before trying again.

Step 4: Removing the Pulley

Once the bolts have been removed, it’s time to remove the pulley from the shaft. This can be achieved by using a pry bar or a flathead screwdriver. Place the flat edge of the tool under the pulley and apply gentle pressure to pry it off the shaft. If the pulley is stuck, gently tap it with a hammer to break any rust or corrosion holding it in place.

Step 5: Cleaning and Inspection

After the pulley has been removed, clean the shaft and the area around it. Look for any signs of wear or damage that could affect the performance of the machine. If the pulley is damaged, consider replacing it before reassembly.

Conclusion

Removing a pulley without a puller may seem like a daunting task, but with the right tools and a bit of patience, it can be done. Always remember to take safety precautions before starting the process and ensure that the machine or motor is not connected to any power source. With these steps, you can effectively remove a pulley without the need for a puller.
