Description
This unit describes the performance outcomes required to return diesel fuel injection system components to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the diesel fuel injection system components, carrying out the overhaul procedures, reassembling and testing the diesel fuel injection system components, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The diesel fuel injection systems include those of agricultural machinery, heavy commercial vehicles, light vehicles, mobile plant machinery, marine vessels or outdoor power equipment.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
