634-9172: Recoil Cylinder

Cat® Recoil Hydraulic Cylinder uses a large recoil spring and greased-filled adjustment cylinder which allows the idler to move forward and back to maintain proper track tension as it absorbs undercarriage shock loads. Cat® Cylinders are configured to contain a quantity of hydraulic fluid. A rod element is coupled to the idler and configured to reciprocate within the recoil cylinder. The idler is configured to exert a force on the rod element to drive hydraulic fluid from the recoil cylinder when the force exceeds a predetermined force. Cat® Cylinders are manufactured with thick tube walls that enable more service lives. This feature, when combined with exclusive Cat® Oversize Seals, can extend cylinder life in many applications. Application: Cat® Recoil Cylinders are used in the undercarriage system front idler of Cat heavy duty equipment. Consult your owner's manual or contact your local Cat Dealer for more information.
