ABSTRACT:
Each track roller of a crawler has a tapered bore in which is fitted a tapered bushing holder, and fitted within the cylindrical bore of the holder is a cylindrical bushing which journals the roller for rotation about a transverse shaft mounted on the track frame of the crawler. Socket head bolts are threaded into the roller to anchor the holder in place. A thrust washer is carried at each side of the roller which prevents the roller from engaging the track frame, the thrust washers also preventing the entrance of dirt and other foreign matter into the region between the shaft and the encircling bushing.
