Competencies DIESEL ENGINES For every task in Diesel Engines, the following safety task must be strictly enforced: Comply with personal and environmental safety practices associated with eye/foot/hand/hearing protection, clothing, hand tools, power equipment, lifting practices, and ventilation. Handle, store, and dispose of fuels/chemicals/materials in accordance with federal, state, and local regulations. The first tasks in Diesel Engines are to listen to and verify the operator s concern, review past maintenance and repair documents, and determine necessary action. I. DIESEL ENGINES A. General 4. Diagnose engine operation (starting and running) including: noise, vibration, smoke, etc.; 6. Identify system components, configurations, and types of the following: cylinder head(s), valve train, engine block, engine lubrication, engine cooling, air induction, exhaust, fuel, and engine braking. 7. Diagnose engine no-crank, cranks but fails to start, hard starting, and starts but does not continue to run problems; B. Cylinder Head and Valve Train 1. Inspect electronic wiring harness and brackets for wear, bending, cracks, and proper securement; 2.
