Abstract

An improved motor mount adjustably tensions the chain in a chain and sprocket driven vehicle. The vehicle has a frame, at least one driven wheel rotating from a wheel rotation point on the frame, a driven sprocket driving the driven wheel. A motor is mounted to the frame and has a driving sprocket at a motor sprocket rotation point on the motor. The driving sprocket is disposed in a plane including the driven sprocket, and powers a chain. An improved mount for mounting the motor from the frame relative to the driven sprocket includes a motor mount for fastening to the engine for disposing the driving sprocket from the engine overlying the driven sprocket powering the driven wheel. A motor mount pivot is provided on the motor mount for pivoting the driving sprocket along the plane including the chain and driven sprocket. A keeper slot is configured within the motor mount, the keeper slot being coaxial about the pivot to enable a keeper to slide relative to the keeper slot during pivot of the motor mount.
