Partial compression of the spring is necessary for assembly or disassembly of the track tensioning apparatus and installation or removal of the recoil lock device. Such compression may be accomplished by utilizing the tensioning apparatus, or before assembly by utilizing a specially configured compression device. The recoil lock device are retained in a lock position by a retainer ring engaging narrowed mid-portions of spatially separated pin members of the recoil lock device.</p> |
