ABSTRACT:
A cut or split bushing having a set of holes or apertures along one or both sides of the bushing for receiving pinching finger elements of a tool. By this structure, one is capable of grasping the bushing at its apertures for axial insertion into or axial removal from a bushing sleeve or boss formed in a support housing for camshaft having the S-cam on one end and a torque arm on the other in a truck brake system. The tool has a resilient arcuate handle grasping portion that applies a spring or resilient action upon the pinching finger elements, the force thereof being such to bias the fingers apart so that one's hand normally forces the fingers together. The fingers may be retained together by a clamping band retaining the fingers in a pinching position so that the bushing may be withdrawn from the supporting housing or journal block which supports the shaft that extends through the bushing.
