RE: 5HP Craftsman Air Compressor Belt

You have a Poly V 460J6 belt. If you check it, It should measure to be 46 inches outside circumference and the six “notches” are normally called Ribs in the industry. Poly-V and Micro-V belts are known as “ribbed V belts” and, if available, the number following the “J” designates the number of ribs. Sometimes the manufacturer leaves the number following the “J” off because of the way the belt is cut from the raw “sleeve” which may have hundreds of ribs before it it cut down to size and the size number is silkscreened onto the belt. You can buy 460J6 belt stock from a number of reputable suppliers. If you have trouble with the air compressor manufacturer’s website, I alway start with Belt Palace’s online store to compare prices. They always seem to have items in stock and offer same day shipping.

Thank you for your contribution!
