Abstract: A compactor wheel is rotatably mounted on a vehicle and comprises a plurality of pads disposed on the periphery thereof for compacting purposes. A cleaning bar assembly is mounted on the axle housing of the vehicle and comprises an integral U-shaped frame having a plurality of cleaning bars secured thereon to extend inwardly between the pads of the compactor wheel for removing material therefrom. The bars are secured on a pair of legs of the frame which straddle the compactor wheel in parallel relationship relative to the rotational axis thereof. Each of the legs has an adapter means secured on an outboard end thereof adapted to selectively attach an outboard support bar thereon to form a box-like frame enclosing the compactor wheel.

Abstract: A resiliently supported face seal arrangement with arcuate seal rings that coact with spaced spherical ramps of a bearing mounting to maintain an effective seal and thus a lube chamber and supply for components with relatively large angular misalignment is disclosed.
