Replacing a timing belt starts with matching the belt you are taking off. This Optibelt Alpha Flex belt carries the part number 400 / H 1735 AFX, an H profile, and a length of 4406.9 mm. Confirm those three details against the old belt before you order.
The simplest way to match this belt is to read the marking on the back of the belt being replaced. If it shows 400 / H 1735 AFX, you have a direct match. If the marking is worn or unreadable, measure the belt and check the profile and length against the H profile and 4406.9 mm given here.
Profile and length are what identify a timing belt. The H profile sets how the teeth engage the pulleys, and 4406.9 mm is the length. Both must line up with the drive. A belt of the same profile but a different length will not fit, and neither will a different profile at the same length.
If the old belt is gone or its marking cannot be read, send us what you have. The part number 400 / H 1735 AFX, the profile, the length, and any photos of the drive and the old belt are enough for our team to confirm the match or suggest an equivalent.
