Dismantle and assemble single cylinder four-stroke petrol engines


Application

This unit describes the performance outcomes required to dismantle and reassemble a single cylinder four-stroke engine. It requires the learner to plan and prepare the task; dismantle the engine and inspect the components; reassemble the engine and check the engine operation; and maintain the work area, tools and equipment.

It applies to those undertaking a Vocational Education and Training in Schools (VETiS) or pre-vocational qualification as preparation to entering the automotive service and repair or automotive manufacturing industry.

The unit is designed for use in a highly supervised context and is not suitable for use in a vocational qualification.

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