Belt drives are often touted as low-maintenance and virtually wear-free. However, the often advertised threefold service life compared to the chain is only achieved if the belt is regularly maintained. If this is not the case, belts wear out or tear and the pulleys are not spared either.
With a 2-mm-Pulley gauge Can the wear of the disc be checked similarly to a chain gauge? The tool is intended as a promotional tool by Gates and, in addition to the gauge, also functions as a bottle opener.
