ABSTRACT:
A hollow cam shaft of the type wherein lubricating oil is distributed to the cam portions includes a rod member positioned inside the shaft pipe member and spaced from the inner pipe surface by shaft end members and guide strips to form a reduced, annular volume to be filled with oil during engine start-up. The method of making the hollow cam shaft includes forming the rod member from a resinous material by injection molding, using a removable mold positioned in the pipe through-hole, and, in a preferred embodiment, flowing the resin through the mold cavity and into a recess located in the distal shaft end member, which recess has an enlarged portion for capturing the hardened resin rod end and facilitating mold removal.
