This Optibelt Alpha Flex timing belt is identified by the code 16 AT5K6 / 4400 AFX. It uses the AT5 profile with a 4400 mm length and a 5 mm pitch. Before fitting it, inspect the drive and sheaves so the new belt runs true from the start.
Check the sheaves for worn grooves, burrs, corrosion or debris that can damage the belt teeth. Confirm the shafts turn freely, the bearings are sound, and the tensioner or idler moves without binding. Misalignment between pulleys will shorten belt life, so correct it before installation.
Verify the drive is clean and dry, with no oil or grease on the pulley surfaces. Compare the old belt marking with the replacement: this belt is an AT5 profile, 4400 mm long, with a 5 mm pitch. If the old belt is worn, stretched or damaged, note the condition of the drive so the same problem does not repeat.
When you request a quote, send the part number 16 AT5K6 / 4400 AFX and the quantity you need. Our team can confirm the belt or suggest an equivalent based on your drive details.
