Abstract
A steering arm assembly for use with railway car trucks having pivotal frames and brake systems is disclosed. The steering arm assembly has two U-shaped sub-assemblies. Each sub-assembly has two side arms connected by a center arm. The side arms each have vertical open paths between top and bottom holes in their surfaces and open side paths through side access holes in their sidewalls. The open side paths intersect the vertical open paths. The vertical open paths are positioned to be aligned over the brake system brake shoe keys and the side access holes are positioned to be aligned with the side windows in the side frame. When it is desired to remove or replace a brake shoe, the brake shoe key may be moved upwardly through the vertical open path. This movement may be facilitated through use of a tool inserted through the side access hole and open side path in the side arm. A method of changing brake shoe keys and the combination of such a steering arm assembly in a railway car truck is also disclosed.
