The Optibelt 400 / H 4720 AFX is an Alpha Flex timing belt with an H profile and a length of 11988.8 mm. Before you install it, inspect the drive and sheaves so the new belt runs correctly.
Check sheave grooves for wear, burrs, or debris, and confirm the sheaves are aligned. Verify that the bushing and fasteners are secure. A worn or misaligned sheave can damage a new timing belt.
Measure the old belt and compare it to the 11988.8 mm length and H profile of the Optibelt 400 / H 4720 AFX. Confirm the belt path and tensioner operation. If the old belt is damaged, note the failure mode to avoid a repeat.
When you are ready to order, send the part number 400 / H 4720 AFX by WhatsApp or email. We carry the Optibelt Alpha Flex line and will reply promptly. If you need help confirming the right belt, our team can assist.
