The Optibelt 40 / 14M 4200 AFX is an Alpha Flex timing belt in HTD 14M profile with a 4200 mm length and a 14 mm pitch. We carry it for maintenance and engineering teams who need to match a belt already in service. To confirm it is the correct replacement, compare the marking on the back of the belt you are removing with the code above.

The most reliable match is the belt itself. Read the code printed on the back and check three things: the profile, HTD 14M; the length, 4200 mm; and the pitch, 14 mm. If those agree with this Optibelt Alpha Flex belt, it is the same size. A belt that has run for years can stretch or wear, so do not measure the old belt to identify it; use the marking.

If the marking is worn off or unreadable, send us what you can see. A photo of the belt back, the drive arrangement, and any remaining characters is usually enough for our team to confirm the profile and length or suggest an equivalent. We reply by WhatsApp or email, so a quote request can move as soon as the part number is confirmed.

When you replace a timing belt, inspect the pulleys and the rest of the drive at the same time. Check for worn teeth, debris in the grooves, and any sign of misalignment before the new belt goes on. On drives that run more than one belt, replace them as a set so the load stays even across the drive.
