The Optibelt 20 / 8M 4200 AFX is an Alpha Flex timing belt with an HTD 8M profile, an 8 mm pitch and a 4200 mm length. Before you fit it, take the time to inspect the drive and the sheaves so the new belt runs true from the first start.

Check the sheaves for worn grooves, burrs, corrosion or embedded debris that can cut into the belt. Confirm the sheaves are clean and aligned, and that the shafts and bearings turn freely without play or roughness. A drive that is out of alignment or has damaged sheaves will shorten the life of any timing belt, including this one.

Verify that the replacement matches the belt you are removing. The Optibelt 20 / 8M 4200 AFX is an HTD 8M profile belt, 4200 mm long, with an 8 mm pitch. Compare the profile and the length against the old belt and the drive documentation before installation.
