Abstract
A chain tensioner having a shoe, a coil spring, and a bushing disposed through the coils of the spring. The shoe has a chain wear surface and a spring wear surface. The coil spring has a coiled section and two legs extending away from the coiled section which contact the spring wear surface of the shoe. The legs of the coil spring impart a spring force on the shoe and cause the shoe to tension a chain.
