Abstract
A low friction finger follower rocker arm is fabricated by starting with a flat metal strip sheet stock section having a stamped configuration with a centralized opening being adapted to be bent later into a channel for such rocker arm. The shaping and hardening of the stock section is carried out prior to such bending. The method steps comprise the following: (a) while substantially in the flat condition (i) shaping the strip sheet stock section to have at least a pair of journal openings aligned on opposite sides of said centralized opening, a pivot surface at one end of the strip sheet stock section, a stud contacting surface at the other end of the strip sheet stock section, such surfaces being aligned with the centralized opening along a line transverse to the alignment of said journal openings, and a pair of grooves aligned with the extremities of the centralized opening and containing the surfaces therebetween, (ii) locally hardening the surfaces and the edges of the opposed openings; (b) bending the shaped strip sheet stock section along the grooves to form a partial channel having side walls with an included angle of no greater than 40.degree. and with said journal openings approaching alignment on a common axis; and (c) inserting a journalized low friction wear assembly with its journals in said opposed journal openings, and then completing the bending of said strip sheet stock section so that the sides of the channel are substantially parallel and locking the wear assembly journals to the channel side walls.
