The Optibelt Alpha Flex timing belt with code 100 AT10 / 3800 AFX is a synchronous belt identified by its AT10 profile, 3800 mm length and 10 mm pitch. When you need to replace a belt, the marking on the back of the old belt is the most reliable starting point.
Read the back of the old belt before you order. Look for the profile, length and pitch, and match them to the data here: AT10 profile, 3800 mm length and 10 mm pitch.

If the old belt is worn or the marking is hard to read, note the drive's sprocket grooves and center distance so we can help confirm the right belt.
