Description
This unit describes the performance outcomes required to recondition engine cylinder heads as part of an engine reconditioning process. It involves preparing for the task, determining engine cylinder head damage and required repair action, preparing reconditioning machines, performing machining to specifications and workplace requirements, reassembling and testing the cylinder head, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The engine cylinder heads include overhead valve or overhead camshaft design cylinder heads in vehicles from all sectors of the industry.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
