Belt Tension 22R-RE & 3VZ-E

The tension on a drive belt is described by Gates as being ideal when there is 1/64" of deflection per 1 inch of belt span. In this case, there is a 4"span, therefor belt deflection should be 4/64" or 1/16". This process of determining proper belt deflections used in cases that you do not have a specialty tool.
