Cog Drive Belt for 4 x 24" belt sander... needed... 315.11781 Craftsman belt sander


Thank you for your question. I am sorry you are having problem with the belt sander. To replace the belt you have to remove the blower housing and blower first. In the image below the blower, housing and blower are marked in the red box. Once it is removed you can take the belt cover off. The below cover is in the greed box. After you have the cover removed,you can clean out any remnants of the old belt. Then you can walk the new belt onto the pulley. This is the tricky part because the belt is made to be tight. First, put the belt on the small pulley. While you hold the belt on that pulley, hook one edge of the belt on the large pulley. Then slowly turn the pulleys while you hold the belt on the pulleys. Once you have it on the pulleys give it a few turns to make sure the belt is tracking properly. If it is, you can reassemble the unit and check the operation. I hope this is helpful. Please let me know if you need further assistance.   Thank you for using Manage my life. Mark T.
