The Optibelt 25 / T10 3400 AFX is an Alpha Flex timing belt with a T10 profile, a 3400 mm length and a 10 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs true from the start.

Check the sheaves for worn grooves, burrs, corrosion or built-up debris, and confirm they are clean and aligned. Look at the shaft bearings and tensioner for play, noise or rough rotation, since these conditions can damage a new belt quickly. Verify that the replacement belt matches the old one: T10 profile, 3400 mm length and 10 mm pitch.

Read the marking on the back of the old belt to confirm the part number before ordering. If the marking is worn or unreadable, measure the length and identify the profile so we can match the Optibelt 25 / T10 3400 AFX. Send the part number and any photos of the drive by WhatsApp or email, and we will confirm the belt or suggest an equivalent.

When you replace a timing belt, inspect the full drive and correct any sheave or alignment issues first. Fit the belt without forcing it over the flanges, then set tension according to your drive specifications. A clean, aligned drive helps the belt seat correctly and reduces the chance of premature wear.
