The Optibelt 25 AT5 / 7800 AFX is an Alpha Flex timing belt with an AT5 profile and a 7800 mm length. Before you fit it, inspect the drive and the sheaves so the new belt runs on a sound system.
Check the sheaves for worn grooves, burrs, or debris that can damage the belt teeth. Confirm the sheave profile matches the AT5 pitch of 5 mm. Misalignment between pulleys will shorten belt life, so verify that the shafts are parallel and the pulleys are in line.
Look for oil, coolant, or dust around the drive, and correct any leaks before installation. Confirm that the tensioner and idler pulleys turn freely and that the bearings are not rough. If the old belt shows uneven wear, the sheave condition or alignment is often the cause.
