When you are replacing a timing belt, the safest match is the one already on the drive. This Optibelt Alpha Flex belt carries the code 85 / 14M 3598 AFX, an HTD 14M profile and a 3598 mm length. Read the marking on the back of the old belt and compare it field by field before you order.
Start with the profile and the length. HTD 14M describes the tooth form and the 14 mm pitch; 3598 mm is the belt length. Both must agree with the belt you are removing. If the old belt is worn or the marking is rubbed away, measure the length and count the teeth rather than guessing from the drive alone.
The code 85 / 14M 3598 AFX identifies this exact Optibelt Alpha Flex timing belt. Write it down exactly as it appears, including the spaces and the slash, and send it to us by WhatsApp or email for a quote. If you are unsure whether this is the correct replacement, send a photo of the old belt’s back marking and the drive arrangement, and we will help confirm it.
Because timing belts are often replaced as part of a planned shutdown, it is worth checking the pulleys and tensioner at the same time. A belt that matches in profile and length will still run poorly if the drive is misaligned or a pulley is worn. Note any abnormal wear on the old belt so the new one is not damaged by the same cause.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Compare the marking on your old belt with 85 / 14M 3598 AFX. The profile must be HTD 14M and the length must be 3598 mm. If the old marking is unreadable, send us the drive details and we will help confirm the match.
- What information should I send for a quote?
- Send the part number 85 / 14M 3598 AFX, the quantity you need, and the profile and length if you have them. A photo of the old belt’s back marking helps us verify the match before we quote.
- Can I replace just one belt on a multi-belt drive?
- On drives that use more than one timing belt, replacing all belts at the same time helps keep the load even. If you are unsure, send us the drive layout and we can advise on the set.
