ABSTRACT:
Structure for fastening the blade of a motor grader to a support carried on the vehicle while enabling sideward sliding movement of the blade includes support brackets each of which has a slot for receiving a slide rail that is secured along the back of the blade. To sustain wear and to facilitate compensating adjustments for such wear, a pair of replaceable wear strips are situated in each slot between the bracket and rail. The two wear strips are locked together by interleaved portions and each has an angled end portion abutting a separate side surface of the bracket. This construction locks the wear strips in place without requiring any additional fastening means to prevent wear strip movement out of the slots during sliding movement of the blade and rails. The pair of wear strips may have similar configurations enabling interchanging of the two strips after a period of time to distribute wear more evenly. Using wear strips of a single shape also simplifies the stocking of replacement parts and forestalls improper installation.
