The Optibelt Omega 3M 177 is a timing belt with an HTD 3M profile, a 177 mm length and a 3 mm pitch. This page covers what to check on the drive before a new belt goes on. Send the part number by WhatsApp or email and we will confirm the belt or suggest an equivalent.

Before fitting the 3M 177, inspect the drive rather than the belt alone. Check the sheaves for worn teeth, hooking, corrosion or buildup in the grooves, since any of these will wear a new timing belt quickly. Confirm the sheaves are aligned and that the shafts and bearings turn freely by hand. If a tensioner or idler is part of the drive, inspect it at the same time.

Confirm the marking on the back of the old belt matches what you expect. The Optibelt Omega 3M 177 is identified by its part number, with an HTD 3M profile and a 177 mm length. If the marking is worn off, measure the old belt and count the teeth so the replacement matches the drive.

For a quote, send the part number 3M 177 plus the profile and length if you have them. A photo of the back of the old belt and of the sheaves helps us confirm the right belt. We reply promptly and can suggest an equivalent where one fits.
