  • When removing or installing the new belts, do not stretch them over the sheaves. Loosen the belts using the belt tension adjustment bolts on the motor mounting base.

  • Once the new belts are installed, using a Browning or Gates tension gauge (or equivalent), adjust the belt tension as follows:
