ABSTRACT

This chapter deals with truck head machining, test, and assembly problems that vary considerably from the one. It discusses the dual responsibility of machining, assembly, and the preliminary and final testing responsibilities of the assemblies involved. The cost of the truck plant downtime was so significant that a team of problem solvers was dispatched to the supplier facility from the corporation headquarters. The chapter presents the description of the process requirements and the difficulties that were experienced. There were serious concerns about the use and comparison of the unrelated tests that were being performed at the supplier and the customer location. Testing system indicated that all the assemblies were acceptable but the engine plant testing indicated that there was an inordinate amount of rejected heads when retested before being assembled to the engine.
