Navistar Truck and School Bus Training
|Covers the 2004 and newer DT466 and 570 engines in IH’s medium duty trucks. This class examines all operating systems: fuel supply and delivery, complete HEUI theory and application, oil pump low pressure and high pressure circuits, all plumbing circuits involved for both systems, computer and injector driver module systems, diagnostic procedures, computer strategies, injector sleeve replacements, common problems and pattern failures.
This class also includes a full electronic demonstrator board to further explain how the engine control system works. A complete cutaway DT466 (EGR) engine will be torn down in the classroom to examine fuel delivery. A wide variety of engine parts is provided for demonstration purposes: cylinder head, turbocharger, fuel injectors, sensors, pumps, a complete fuel system, and more. A cylinder head, which has been cut in half to expose all passageways, also is used. The class expands on diagnostics with time spent in the shop doing live tests with the factory MD Fleet software on running Navistar equipped trucks. A cutaway variable turbocharger accompanies this class.
A full-color training manual is provided.
