This unit describes the performance outcomes required to grind engine camshafts to specific under sizes. It involves preparing for the task, determining camshaft damage and required repair action, preparing and using grinding machines to grind camshafts to specifications and workplace requirements, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The camshafts include those of engines in vehicles from all sectors of the industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
