The Optibelt 300 / H 3700 AFX is a timing belt from the Alpha Flex series with an H profile and a length of 9398 mm. Before you fit a new synchronous belt, check the drive and the sheaves so the replacement runs true.
Inspect the sheaves for worn grooves, burrs, corrosion or buildup, and confirm they are aligned and secure. Check bearings, shafts and tensioners for play, noise or rough rotation, and correct any misalignment or runout before installation. A drive that is not square or tight will shorten the life of any belt.
Look for oil, coolant or debris around the drive and clean it off; verify that guards and covers are in place. Confirm the new belt matches the old marking: Optibelt 300 / H 3700 AFX, profile H, length 9398 mm. If the old belt is worn or the marking is unreadable, send us the part number and we will confirm the correct belt or suggest an equivalent.
When you request a quote, include the part number, the quantity and any details from the drive nameplate. We carry Optibelt belts and can help you match the right timing belt for your application.
