Inspecting / Replacing a Worn Compressor Belt
•
If your air compressor is equipped with a protective cage, find the screws or clips that hold the cover in place and remove them.
•
Inspect the belt and check for cracks or signs of wear.
•
If replacement is necessary, move onto the next step. Otherwise, replace the cage / belt guard and repeat the inspection as scheduled.
•
To remove the worn / damaged belt, grasp it firmly and while pulling it over the large pulley, rotate the pulleys by hand and the belt will
remove from all pulleys.
•
Take the new belt, place it over the small pulley and work it onto the large pulley by hand-turning it in a forward motion until it is securely on
the large pulley. Replace the cage / belt guard.
