The Gates 11M 1250 JB is a Polyflex JB narrow V-belt with a length of 1232 mm. Before you install it, take a few minutes to inspect the drive and sheaves. That simple step helps you get the full service life from the new belt and avoids repeat failures.

Check the sheave grooves for wear, rust, or debris. Worn grooves can cause the belt to sit too deep, leading to slip and heat buildup. Look for any nicks or burrs on the flanges that could cut the belt sidewalls. Also confirm that the sheaves are aligned and that the bearings turn freely.

Inspect the old belt for signs of what went wrong: cracking, glazing, or uneven wear. These often point to a misaligned drive or a bad sheave. If the drive uses multiple belts, replace them as a set to keep loads balanced. Clean the grooves before fitting the new belt, and check tension after the first few hours of running.
