Abstract
A process for the manufacture of a lift arm assembly for a work vehicle includes a plurality of closely controlled process steps. The lift arm assembly is a large fabrication which, when assembled to the vehicle, interconnects with several other components and work implements. In order to properly connect with these other components, the various holes, throughbores, and connecting surfaces must be machined within close tolerances. The subject process provides the controls for holding the tolerances within specified and acceptable ranges. The lift arm assembly produced by the subject process is used for lifting and manipulating a bucket or other type of work implement.
