Abstract
A cam bushing assembly for supporting a camshaft in a cam braking system on a vehicle has a bushing retainer removable from a brake spider, and a bushing removable from the bushing retainer. The bashing retainer is bolted to the brake spider and can be removed simply by unfastening the bolts. A bushing is removably disposed within the bushing retainer. The bushing can be removed from the bushing retainer without removing the retainer from the brake spider. Further, the bushing assembly incorporates strategically located grooves that significantly increase lubricant flow to and around the camshaft.
