5 Tricks To Solving Belt Noise
Engineering a belt system is one of the most difficult jobs for OEMs. There are contact, frictional, centrifugal and peripheral forces that must be taken into account. If they get it right, the belt will be quiet, efficient and last 100,000 miles. If they get it wrong, the belt will be noisy or rob the engine of power. For technicians, the job is even tougher. Variables that the engineer did not factor in can put the belt and your diagnostic skills to the test. But there are four techniques you can use to solve belt noise problems.
