When you need to replace a timing belt, the fastest path is to match the belt you are removing. This Optibelt Alpha Flex belt carries the code 50 AT5K6 / 11600 AFX, which identifies it in the Optibelt line. We supply it for maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
Start by reading the marking on the back of the old belt. Confirm that it shows the same code, 50 AT5K6 / 11600 AFX. Then check the profile and length: this belt is an AT5 profile with a 5 mm pitch and a length of 11600 mm. Those three details, the code, the AT5 profile and the 11600 mm length, are what you need to compare before ordering.
If the old belt is worn or the marking is unreadable, measure the length and identify the profile from the pulley grooves. The AT5 profile and 5 mm pitch must match the drive. This is a timing belt, so tooth engagement matters. Once you have the code or the profile and length, send them to us by WhatsApp or email and we will confirm the belt or suggest an equivalent.
