description A spring loaded track tensioning assembly for a track on a track driven vehicle has a spring subassembly that is retained on a spring shaft under a preload with a first fixed spring retainer and a second slidable spring retainer. The spring shaft has an outer end that extends beyond the second spring retainer and the outer end is slidably received in a bore in a piston or actuator shaft of a grease cylinder, with the end of the actuator shaft bearing on the second spring retainer. The grease cylinder contacts and applies a force to the second spring retainer, for initial positioning of the tensioning assembly, and additional loads on the first spring retainer that compress the spring cause the outer end of the spring shaft to slide in the bore of the actuator shaft as the second spring retainer slides along the spring shaft.
