Abstract
A rocker arm assembly for translating force between an intermediate member in communication with a camshaft of an internal combustion engine and a valve supported in a cylinder head of the engine. The rocker arm assembly includes a tube member and an arm. The tube member has first and second ends, a substantially cylindrical inner surface, and a tapered outer surface. The arm has a body extending between a pad for engaging the valve of the engine, and a socket for engaging the intermediate member of the engine. The body also has a tapered bore disposed between the pad and the socket. The tapered bore of the body of the arm cooperates with the tapered outer surface of the tube member so as to define a lock for constraining the arm to the tube member at a predetermined position between the first end and the second end.
