Abstract: Disclosed are various exemplary embodiments of a retainer system for a ground engaging tool. In one exemplary embodiment, the retainer system may include a lock having a lock rotation axis and including an outer surface extending about the lock rotation axis. The retainer system may also include a retainer bushing including an inner surface extending about the lock rotation axis, where the inner surface is configured to rotatably receive the outer surface of the lock. The outer surface of the lock and the inner surface of the retainer bushing may be aligned substantially parallel to the lock rotation axis.

Abstract: A ripper shank protector including a first side, a second side, and a center face extending between the first side and the second side. The shank protector further includes a first protector mount in the first side, and a second protector mount in the first side, the second protector mount including an open-ended slot that allows sliding the slot onto a mounting projection extending from a ripper shank.

Abstract: A ripper shank assembly including a ripper shank and a ripper tip mounted to a front end of the ripper shank. The ripper tip includes an upper surface with a first ridge extending upward from the upper surface. The ripper shank assembly further includes a ripper shank protector mounted to a front edge of the ripper shank rearward of the ripper tip, the ripper shank protector including a second ridge on a center face of the ripper shank protector, wherein a portion of the second ridge adjacent a front end of the ripper shank protector has a height greater than a height of the first ridge.

Abstract: The design and construction of past articulated pistons has failed to include the most efficient cooling reservoir for transferring heat from the piston to the coolant. The present invention overcomes these problems by using an annular cooling recess of a precisely defined cross sectional shape and volume and a baffle plate fixedly sealingly attached in heat conducting relationship to the piston member to form a cooling gallery. The baffle plate has an opening therein and an upwardly extending raised portion to preestablish a trapped volume of coolant therein. The assembly, positioning of the plate and the preestablished trapped volume insures high efficiency of the coolant to absorb heat through the scrubbing action of the coolant on the recess and the heat absorbed by the trapped coolant because of the heat conducting relationship of the plate and the piston member.
