ABSTRACT:
An idler sprocket mount including a pair of modular block assemblies for mounting an idler sprocket for endwise sliding movement generally parallel to a track frame of a crawler tractor. Each block assembly defines a horizontally elongated channel allowing for endwise sliding movement of the frame therethrough to permit the idler sprocket to recoil parallel to the track frame. The elongated channel includes at least one bearing surface along which a wear surface of the track frame slides. A spring biased assembly provides a substantially constant vertically directed force against the frame to resiliently urge the wear surface against the bearing surface of the channel thereby automatically compensating for wear between the interfacing surface and inhibiting vertical bounce of the idler sprocket relative to the track frame.
