Abstract

PCT No. PCT/US79/00763 Sec. 371 Date Sept. 24, 1979 Sec. 102(e) Date Sept. 24, 1979 PCT Filed Sept. 24, 1979 PCT Pub. No. W081/00897 PCT Pub. Date Apr. 2, 1981 The push arms of a conventional bulldozer assembly are mounted on a track roller frame of a track-type tractor by bearing assemblies, each including a pair of bearing caps. One of the bearing caps is welded to the push arm, thus requiring that it be cut-off upon replacement thereof. In addition, the bearing cap welded to the push arm must be selectively hardened to avoid stress cracking in the heat affected zone of the weld. This invention overcomes the above problems by providing a bearing assembly (16) which includes a pair of separable first and second bearing caps (17, 17') which are secured together and to the push arm by common fasteners (28).
