Installation

To increase airflow

Loosen variable sheave set screw and turn sheave clockwise.

To decrease airflow

Loosen variable sheave set screw and turn sheave counter-clockwise.

To increase belt tension

Loosen the nut (next to the idler sheave) that secures the sheave in place. With a wrench, apply pressure clockwise on the outside nut (round headed one), until tension desired is reached. While holding pressure with the tension nut, retighten the nut next to the idler sheave.
