ABSTRACT:
A rocker arm assembly for an internal combustion engine is provided which is lightweight and inexpensive to manufacture, which securely mounts and supports a pair of rocker arms and associated structures on the cylinder head of an internal combustion engine, and which provides and maintains a supply of lubricant to the rocker arm bearing structures, valves and push rods. The rocker arm assembly includes a two part pedestal which clamps the shaft on which the rocker arms are journaled to the engine. The base portion of the pedestal includes a pair of positioning projections which position and support the pedestal so that the proper alignment of the rocker arms relative to the longitudinal axis of the engine is achieved and maintained.
