Abstract: A wet brake assembly and method for cooling separator plates in a wet brake assembly are disclosed. The wet brake assembly may comprise a hub rotatable about an axis and a brake pack. The hub may include a plurality of legs that define a plurality of troughs in the hub. The brake pack may include a plurality of friction disks disposed around and rotatable with the hub, and a plurality of stationary separator plates. Each separator plate may define a gap with at least one of the friction disks. Each trough may define an unobstructed axial flow path between the hub and the brake pack, and each gap may define a radial flow path across the brake pack. An intersection between the axial flow path and the radial flow path is configured to change positions with rotation of the hub and the friction disks.

Abstract: A bearing assembly for an oscillation joint on a machine having a tandem wheel drive. The bearing assembly rotatably supports an oscillating hub rotatably connected to a shaft. The bearing assembly includes a spacer having a stop face and an axial contact face. The spacer is sized and arranged to face a shoulder of the oscillation joint and to also support an inboard thrust bearing having a surface area greater than a surface area of the shoulder.

Abstract: A method for retrofitting an oscillation joint to provide increased wear life and a kit for retrofitting an oscillation joint to provide increased wear life are provided. The method and kit include a spacer having a stop face and an axial contact face with the stop face generally smaller than the axial contact face. The spacer is sized and arranged to face a shoulder of the oscillation joint and to also support an inboard thrust bearing having a surface area greater than a surface area of the shoulder.
