Abstract: A seal packing guard is provided in a roller assembly of a machine, such as a track carrier roller of a track-type undercarriage. The roller assembly includes a roller mounted on a shaft and having a seal retaining lubricant between the roller and the shaft. A collar and an inner surface of the roller form a seal cavity placing the seal in fluid communication with an ambient atmosphere surrounding the roller.

Abstract: This invention describes a system to maintain equal pressure in a pair of dual tires, and also incorporates a valve mechanism that will prevent one dual wheel tire from going flat in the event the other dual wheel tire experiences a rapid air loss. Dual wheels are typically mounted on the vehicle hub with both wheel disc faces in direct contact with each other. To ensure equal pressure in both tires, this invention has air passageways machined into the wheels such that the air passageways meet at the interface between the wheels where the wheel disc faces are in direct contact. These junctions are sealed by a rubber seal or gasket. Both tires can then be inflated or deflated simultaneously through a standard air valve located on either wheel. Where a dual wheel arrangement requires the use of an intermediate piece between the dual wheels, air passageways can connect the two-piece wheels via intermediate air passageways going through the common intermediate piece.
