This Optibelt 85 / 14M 3906 AFX belt is an HTD 14M timing belt from the Alpha Flex series. It has a 3906 mm length and a 14 mm pitch. Before you fit it, inspect the drive and sheaves so the new belt runs correctly.
Check the sheaves for worn grooves, burrs, or debris that can damage a new timing belt. Confirm the sheave profile matches the HTD 14M profile and that the belt length of 3906 mm suits the drive layout. Misaligned or worn sheaves will shorten belt life even when the replacement is correct.
