ABSTRACT:
A rocker arm and method of making same are provided. The rocker arm is of the cam-follower type and is preferably made from a stamped metal piece and a stamped metal strip, the latter preferably being of a hardened alloy. A rounded recess is formed at one end portion of the metal piece and facing away from the metal strip to receive a lifter post having an end on which the rocker arm can pivot. The metal piece also has an additional recess at another end portion to receive an end of a valve stem. The metal strip has an intermediate convex portion facing away from the metal piece to be engaged by a cam. The metal piece has a hole extending through the piece and communicates with the rounded recess while the strip forms a groove communicating with the hole and extending toward the convex portion to supply lubricating fluid from the convex portion to the rounded recess. After the metal piece and the strip are partially stamped, end tabs thereon are welded together and the contiguous portions are brazed, further stamped, and finish formed. The end tabs are then removed and the resulting rocker arm is heat treated and cleaned to complete the process.
