New unit of competency. |
Application
This unit describes the performance outcomes required to fit sleeves to restore engine cylinder blocks and to bore and hone the sleeves to specific tolerances. It involves preparing for the task, assessing damage and determining required repair action, boring, sleeving and honing engine cylinders, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The engines include those in vehicles from all sectors of the industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
