The Optibelt 100 AT10 / 11800 AFX is an Alpha Flex timing belt with an AT10 profile, a 10 mm pitch and an 11800 mm length. Before you fit a replacement, inspect the drive and sheaves so the new belt runs true and reaches its expected service life.
Check the sheaves for worn grooves, burrs, corrosion or embedded debris, and confirm that the flanges are not bent or rubbing. Misaligned shafts or a sheave that is loose on its taper will shorten belt life regardless of the belt's condition. Clean the grooves and verify that the sheave teeth match the AT10 profile and 10 mm pitch of the Optibelt 100 AT10 / 11800 AFX.
Confirm the belt path, tensioner condition and any idler bearings before installation. A tensioner that does not move freely or an idler with play will affect tracking on a belt of this length. Record the part number from the back of the old belt and compare it with the Optibelt 100 AT10 / 11800 AFX so the profile, pitch and 11800 mm length match the drive.
