The marking on the back of a timing belt is the fastest way to identify the correct replacement. This Optibelt Alpha Flex belt is marked 25 T5K6 / 3600 AFX, a T5 profile with a 3600 mm length and a 5 mm pitch. We carry it for maintenance and engineering teams that need to match an existing drive without guesswork.
When a timing belt fails, the old belt is your best reference. Read the full marking before it is discarded: the profile, length and any suffix all help confirm the exact part. In this case, the belt is an Optibelt Alpha Flex timing belt with a T5 profile, 3600 mm length and 5 mm pitch. That data is enough to identify the belt without measuring a worn or stretched example.
If the marking is worn or unreadable, check the drive for other clues. The belt's profile and length are the critical dimensions for a T5 timing belt, and the 3600 mm length and 5 mm pitch are the values to match. Send us the complete marking from the back of the belt, along with any other identification you have, and we will confirm the right Optibelt belt for your application.
