Remove the Old Belt

To remove the old belt, first, remove the motor hood cover. Then, locate the rear roller adjustment bolts and loosen them with a wrench. This will allow you to loosen the tension on the belt. Once the tension is released, you can carefully slide the belt off the deck and roller.

Clean the Deck and Roller

Once you’ve removed the old belt, take the opportunity to clean the deck and roller. Use a soft cloth or brush to remove any dirt or debris from the surface of the deck and roller. This will help to prevent any damage or wear to the new belt.

Install the New Belt

To install the new belt, first, position it on the deck, making sure it’s centered and straight. Then, slide the belt onto the rear roller and adjust the tension bolts to tighten the belt. Make sure the belt is properly aligned and tensioned, and then test it by walking on the treadmill at a slow speed.

Adjust the Belt Tension

After installing the new belt, it’s important to adjust the tension to the proper level. This will ensure that the belt doesn’t slip or wear too quickly. Consult your owner’s manual or the manufacturer’s website for specific instructions on how to adjust the belt tension for your treadmill.

Test the Belt

After adjusting the tension, test the belt again by walking on the treadmill at a slow speed. Make sure the belt is properly aligned and tensioned, and that it’s not slipping or making any unusual noises.
