A vibratory mechanism is provided for a compacting work machine . The vibratory mechanism includes a first/outer eccentric weight and a second/inner eccentric weight . The second weight has a cavity with a movable mass that when rotated in a first direction opposes the first eccentric weight and when rotated in a second direction the movable mass combines with the first eccentric . The second eccentric weight is also manually indexable relative to the first eccentric to a plurality of distinct positions giving a plurality of different amplitude vibratory impact forces when rotated in either of the first and second directions

Vibratory mechanism

A wheel assembly for a work machine, such as a mining dump truck, comprises a rotatable wheel having inboard and outboard rims mounted thereto. The outboard rim is mounted to a segmented rim-mounting flange which is secured to the inboard side of a flange projecting from the wheel. A final drive adapter is secured to the outboard end of the wheel opposite the segmented rim mounted flange. The segmented mounting flange permits the use of a larger final drive ring gear than in known wheel assemblies. Moreover, because the mounting flange is segmented, it can be fastened to the wheel inboard of the gear reduction housing, which permits the final drive assembly to be serviced without removal of the outboard rim from the wheel. Related methods are also disclosed.
