The Optibelt B 77 KB is a banded V-belt of 2032 mm length from the KB series. Banded construction ties the ribs together so they run as one unit on multi-groove drives. Before you fit it, inspect the drive and the sheaves.
Check each sheave groove for wear, burrs and debris, and confirm the grooves are not bottomed out or hooked. Misaligned sheaves and worn grooves are common causes of premature belt failure, and a new banded V-belt will wear the same way if the drive is left as it is. Verify the sheaves are aligned and the take-up has enough travel for the 2032 mm length.
Confirm the belt marking on the back of the old belt matches the Optibelt B 77 KB before you order. On banded drives, replace the full set at once so all belts share the load evenly. Send the part number and the quantity you need by WhatsApp or email, and we will confirm the B 77 KB for your drive.
