The Optibelt 40 / 14M 6650 AFX is an Alpha Flex timing belt with an HTD 14M profile and a 6650 mm length. Before you fit it, inspect the drive and sheaves so the new belt runs true and wears evenly.
Check the sheaves for worn grooves, burrs, corrosion or debris, and confirm the pulleys are aligned and secure. Verify that the shaft bearings turn freely and that the tensioner, if present, moves smoothly through its range. A drive that is out of alignment or has damaged sheaves will shorten the life of any timing belt, including this one.
Confirm the belt marking on the back matches the part number 40 / 14M 6650 AFX, the profile is HTD 14M and the length is 6650 mm. The 14 mm pitch identifies the tooth spacing for the HTD 14M profile. If you are replacing a belt that has run for some time, inspect the entire drive for the cause of any unusual wear before installing the new belt.
To request a quote, send the part number 40 / 14M 6650 AFX by WhatsApp or email. If you need to confirm this is the right belt for your drive, include the current belt marking, the pulley tooth count and the center distance. The team can help confirm the correct belt or suggest an equivalent.
