The Optibelt 3M 291 is an Omega timing belt with an HTD 3M profile, a 291 mm length and a 3 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs on clean, true surfaces.
Check the sheave grooves for wear, debris or burrs, and confirm the flanges are not bent or rubbing. Misalignment between sheaves will shorten belt life, so verify that the shafts are parallel and the belt tracks straight by hand. Any roughness or hooked groove edges should be addressed before the belt is seated.
Confirm the part number on the old belt matches the Optibelt 3M 291 and that the profile and length suit the drive. Turn the drive through by hand to check the mesh and tension before running it under load. If you need help confirming the right belt for your application, send the part number and drive details by WhatsApp or email for a quote.
