Cast take-up tumblers are mounted on each end of the take-up axle. These tumblers are fitted with manganese-bronze bushings protected by a sealed hubcap. A vee-ring face seal protects the take-up bushing from dirt contamination. A square take-up axle fits into rectangular slots in the crawler frame which permits the axle to be moved forward and backward for belt adjustment. Shims are inserted fore and aft of the axle in these slots to position, tension and locate the tumbler and crawler belt.

TRUCK FRAME The truck frame is a stress relieved welded cellular box structure which utilizes impact resistant steel in the major load carrying members. The low temperature toughness of the steel assures adequate strength and durability across a wide range of temperatures frequently encountered in machine applications. A fabricated support structure welded integrally into the truck frame supports the center pintle hub area. The inner diameter of the hub is machined to accept the center pintle bushing. Truck frame surfaces which mate to crawler side frames and swing rack are shop machined to assure proper alignment and solid foundation.
