When you need to replace a timing belt, the fastest path is matching the marking on the old belt to the same profile and length. This Optibelt Alpha Flex belt is identified as 40 / 14M 3906 AFX, an HTD 14M profile timing belt with a 3906 mm length and a 14 mm pitch. We carry it for maintenance and engineering teams that want a direct match without guesswork.

Start by reading the back of the belt you are removing. The part number 40 / 14M 3906 AFX tells you the profile and length, and those are the two values to compare first. The HTD 14M profile and 3906 mm length should match the belt on the drive. If the old belt is worn or the marking is unreadable, measure the length and confirm the profile before ordering.

This is a timing belt, also called a synchronous belt, so it must match the sprocket grooves exactly. The 14 mm pitch is the distance between tooth centers, and the HTD 14M profile is a specific tooth shape. A belt with the same length but a different profile will not seat correctly. Use the code 40 / 14M 3906 AFX when you request a quote.

If you are replacing more than one belt on the same drive, it is good practice to replace them as a set. Send the full marking from each belt, along with the equipment make and model if you have it. Our team can confirm the Optibelt 40 / 14M 3906 AFX or suggest an equivalent based on the profile and length you provide.
