The Optibelt 400 / H 555 AFX is a timing belt from the Alpha Flex series with an H profile and a length of 1409.7 mm. Before you install it, inspect the drive and sheaves so the new belt runs true from the start.
Check the sheaves for worn grooves, burrs, or debris that can damage the belt. Confirm the sheave profile matches the H profile and that the sheaves are aligned. Measure the center distance and verify the 1409.7 mm length fits your drive layout.
Look at the old belt for uneven wear or cracking. If the drive uses multiple belts, replace them as a set to keep loads balanced. Clean the sheaves and check the tensioner and idler pulleys before fitting the new belt.
Send us the part number 400 / H 555 AFX or the marking from the back of the belt. We carry the Optibelt Alpha Flex line and can help confirm this H-profile timing belt for your application.
