Task B-5 Services, diagnoses and repairs base engines
Task Descriptor
Heavy duty equipment technicians must diagnose and service the base engine and its components to ensure proper engine function and reduce down time. A base engine is the assembled block and head including internal components and gear trains (long block). Servicing includes the adjustment of components as well as their routine maintenance. Diagnosing is required to locate failures to effectively perform repairs on the engine, which may include replacement or rebuilding of components.
