This unit involves the skills and knowledge required to conduct maintenance and major overhauls of fixed or pad mounted internal combustion engines.

An overhaul is a thorough examination of a fixed or pad mounted internal combustion engine, with repairs or changes made, as required. This may mean taking apart an internal combustion engine to examine and repair.

Competency in this unit requires the ability to plan work, assess an internal combustion engine's condition, remove auxiliary systems, overhaul and maintain an internal combustion engine, replace auxiliary systems and to report on all completed work tasks. Individuals will, in general, work under supervision in an electrical, electronic and/or mechanical equipment repair workshop or on site.

Power generation maintenance personnel are typically trained and authorised to receive permits to work.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Note: Workplace practice

The application of the skills and knowledge described in this unit of competency may require a licence or training permit to practice in the workplace, where work is carried out on gas and electrical installations. Additional and/or other conditions may apply under state and territory legislative and regulatory licensing requirements.
