摘要： A wheel assembly is disclosed. The wheel assembly may have a hub with a first spline, a second spline, and a slot separating the first spline and the second spline. The first spline, the second spline, and the slot may extend from a front end to a rear end. The wheel assembly may also have an outer rim configured to mount a tire. The wheel assembly may further have an inner rim extending from a rim front end to a rim rear end. The inner rim may have a notch disposed at the rim front end and a tab disposed at the rim rear end. The tab may slidingly engage with the slot. The wheel assembly may have a locking block, which may slidingly engage with the notch and the slot at the front end. Further, the wheel assembly may have a bolt connecting the mounting block to the hub.

摘要： A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube.
