When aligning with the Easy-Laser® XT190 BTA you reduce the wear on sheaves/pulleys, belts, bearings and seals, and you also get lower noise and vibration levels. The accuracy of the digital readout means that you can align within prescribed tolerances and rely on the result. Especially transmissions with two or more belts, or wide belts, are highly affected by misalignment, causing large differences in belt tensions and also increased wear and tear on edges.
