Abstract
Tools and methods for indenting and assembling a switching rocker arm assembly having an inner arm, an outer arm and a latch. The tools and methods are directed to eliminating requirements for matched sets of components of rocker arm assemblies so that the assembled indented parts have desired latch lash tolerances. The tools used include fixtures and clamps for indenting kidney-bean shaped passages in an outer arm that mount a pivot axle of the outer arm. The tools used may also include a fixture and clamps for indenting a latch shelf of the inner arm. Indenting the inner arm and outer arm using these methods and fixtures results in switching rocker arm assemblies that fit together, and when assembled into a valve, have a desired latch lash.
