A thrust ring comprises a body including a cylindrical outer surface, a cylindrical inner surface, defining a central axis, an axial direction, a circumferential direction, a first axial end, a second axial end, and at least one recess on the first axial end, and at least one protrusion extending from the cylindrical inner surface toward the central axis.

A closed-loop seal having an irregularly shaped profile to seal a pivot assembly of a track assembly comprises a body comprising an inner diameter wall, an outer diameter wall, a first sidewall, and a second sidewall, wherein at least one pairing of the inner and outer walls and the first and second sidewalls are non-parallel. The irregularly shaped profile can comprise a curved rectangular profile or a trapezoidal profile. Walls of the body can be joined at curved surfaces having uniform or different radii of curvature. The seal can comprise urethane.

A face seal assembly includes a first face seal member having a first upper radial surface defining an upper radial slot with a sealing surface and a second face seal member having a second upper radial surface. A sealing member extends from the second upper radial surface and contacts the sealing surface.

A snowmobile ice scratcher has a wire form in the shape of a hook secured to a track frame of the snowmobile. The wire form has a coil portion at the track frame and a downwardly extending leg portion that in an undeflected position has an elongate snow/ice spray generating portion configured as a flattened wire segment portion oriented downwardly, forwardly, and inwardly for generating snow/ice spray on hard packed snow and/or ice surfaces. An upwardly facing flat surface of the elongate snow/ice spray generating portion faces upwardly, inwardly, and forwardly and creates an ice/snow spray as the snowmobile is moving forward that is primarily directed inwardly to provide improved lubrication of the track assembly and improved deposition of ice/snow spray under the tunnel on a heat exchanger, thereby providing improved cooling of the snowmobile engine. The hook shape of the leg portion allows rearward operation of the snowmobile without damage to the ice scratcher.

A vehicle including at least one wheel and at least one hub assembly associated with the at least one wheel. The at least one hub assembly includes a hubcap. The hubcap has a transparent body configured for housing a lubricant, a fill port, and at least one continuous indication feature such that a lubricant volume is indicated in any orientation of the hubcap.

A lubricating oil maintenance cap assembly includes a cap having an outer side, and an inner side, a shield, anchor assemblies, the shield is applied to the inner side of the cap, and the anchor assemblies anchor the shield to the cap. The cap is fashioned of a first material, the shield is fashioned of a second material, and the second material is different from the first material and is more thermally resistant than the first material enabling the shield to thermally shield the inner side of the cap.
