Abstract
A recoil system for a track assembly having a track roller frame and an idler movable is provided. The recoil system includes a spring, a track adjust cylinder, an end plate and a track adjust piston received in the track adjust cylinder. The track adjust cylinder and the track adjust piston are movable in first and second directions in response to movement of the idler with movement of the track adjust cylinder in a second direction compressing the spring against the end plate. The track adjust cylinder is adapted to rotate with the first end of the spring relative to the track adjust piston as the spring compresses and extends in response to movement of the track adjust cylinder in the first and second directions and wherein the second end of the spring is fixed against rotation relative to the end plate.
