This Optibelt Alpha Flex timing belt is identified by the code 100 AT20 / 9400 AFX. It uses the AT20 profile with a 20 mm pitch and a 9400 mm length. Before fitting it, inspect the drive and sheaves so the new belt runs correctly.
A timing belt replacement is a good moment to check the whole drive. Look at the sheaves for worn grooves, buildup or damage, and confirm they are aligned and secure. Check that the shaft turns freely and that no components interfere with the belt path. Correcting these points before installation helps the new belt seat properly and avoids repeat failures.
The AT20 profile and 9400 mm length define where this belt fits. Verify the marking on the old belt matches 100 AT20 / 9400 AFX before ordering. If the marking is worn or unreadable, measure the profile and length and send those details with your request. We carry the Optibelt Alpha Flex line and can confirm the right belt for your drive.
