The Optibelt 3VX KB 1250 is a banded V-belt from the Super KBX-Power series, with a 1250 mm length. Before you fit it, inspect the drive and sheaves so the new belt seats and runs as intended.
Check sheave grooves for wear, rust, or embedded debris. Worn grooves let a banded V-belt sit too deep, which reduces grip and shortens belt life. Confirm the sheaves are aligned and the grooves match the 3VX profile. Spin the sheaves by hand and look for roughness, wobble, or binding that would affect the new belt.
Verify the belt path and tensioning arrangement. The 3VX KB 1250 is a banded V-belt, so all ribs must seat evenly in their grooves without twisting or riding on the sheave edges. Confirm the length fits the drive layout before installation: 1250 mm. If the old belt shows uneven wear or missing ribs, correct the drive condition first, then fit the replacement.
