Rotary Belt Tensioner
The Rotary Belt Tensioner system uses a 3/4”-headed bolt and a 15/16” or 1”
nut to set belt tension by positioning an arm between the Tensioner Pulley and
the Tensioner Base. Ridges on the Base mark the amount of tension.
1. Loosen the Bolt Head.
2. Rotate the Tensioner Nut clockwise until the desired belt tension is
achieved.
3. Tighten the Bolt Head.
4. DO NOT OVER-TIGHTEN.
