The Optibelt 300 / H 3150 AFX is a timing belt in the Alpha Flex series with an H profile and an 8001 mm length. To match it to the belt you are replacing, confirm the profile and length from the old belt's back marking or a measurement.
Start with the belt currently on the drive. Read the marking on the back: it should show the profile and length. If the marking is worn or missing, measure the pitch length and compare it to the 8001 mm value for this belt. The profile is H, so the tooth shape must match the pulleys. A belt with the same length but a different profile will not seat correctly.
Once you have confirmed the profile and length, note the part number 300 / H 3150 AFX. This is the number to send when requesting a quote. If the old belt is a different brand, the same profile and length are the key details to compare. We carry the Optibelt 300 / H 3150 AFX and can help confirm it is the right belt for your drive.
