When a timing belt reaches the end of its service life, the fastest way to get the correct replacement is to match the belt you are removing. This Optibelt Alpha Flex belt is identified by its AT10 profile, 3800 mm length and 10 mm pitch. Confirm those three details against the old belt before you request a quote.

The marking on the back of the belt is the primary reference. Look for 150 AT10 / 3800 AFX and compare it with the data here. Profile and length are the critical dimensions: AT10 describes the tooth profile, 3800 mm is the length, and the 10 mm pitch is the distance between tooth centers. If the old belt is worn or the marking is unreadable, measure the length and count teeth only as a cross-check, not as a substitute for the part number.

Because timing belts are often replaced as part of a drive service, inspect the pulleys and tensioner at the same time. Check for worn teeth, cracks, glazing or missing sections on the belt you remove, and note any pulley damage. If the drive uses more than one belt, replacing them as a set helps keep the drive balanced. Send the full marking and any photos of the old belt if you need help confirming the match.

If you are unsure of the exact belt, include the old marking and we can help confirm the right belt or suggest an equivalent.
