ABSTRACT:
An engine tensioning system including tensioner arms and a rotary actuating tensioner capable of driving multiple tensioner arms making multiple chain or belt contacts. The rotary actuating tensioner has connector pins fixed to a rotating surface to which tensioner arms are attached. Rotation of this surface is accomplished through a combination of springs and hydraulic pressure. When the surface rotates, the attached tensioner arms are driven laterally against the engine chain or belt, keeping it taut.
