When you are replacing a timing belt, the most reliable starting point is the marking on the belt you are removing. This Optibelt Alpha Flex belt is identified as 25 AT5K6 / 8400 AFX, with an AT5 profile, an 8400 mm length and a 5 mm pitch. Use those figures to match the belt on your drive before you order.
Read the back of the old belt and compare each element with this listing. The profile is AT5 and the pitch is 5 mm, so the tooth form and spacing must correspond to the pulleys on your drive. The length is 8400 mm; a belt of a different length will not tension correctly even if the profile looks similar.
If the marking is worn or unreadable, measure the old belt and note the drive arrangement, then send the part number 25 AT5K6 / 8400 AFX and your details to our team. We carry Optibelt Alpha Flex timing belts and can confirm that this belt matches what you are replacing or suggest an equivalent.
For drives that run more than one belt, inspect all of them at the same time. Replacing a single belt on a multi-belt drive can leave the remaining belts at a different stage of wear. Confirm the quantity you need and include it with your quote request.
