Application

This unit of competency has been developed for Engineering Tradesperson - Mechanical apprenticeship training and the recognition of trade-level skills in precision fitting and mechanical repair.

It defines the trade-level fitting skills and knowledge associated with manufacturing of new parts/components and fitting mechanical engineering components into assemblies or sub-assemblies to specifications and specified tolerances.

The skills and knowledge described by this unit are applied in occupational and work situations associated with fitting, mechanical trade and maintenance work.

Where the knowledge and skills associated with machining or welding are required, the appropriate units should also be selected.

Where additional or higher marking out skills are required unit MEM12006 Mark off/out (general engineering) should also be selected.

Where the knowledge and skills associated with the installation, removal, repair or replacement of mechanical seals is required unit MEM18012 Perform installation and removal of mechanical seals should also be selected.

Where the knowledge and skills associated with high pressure fluid power seals is required unit MEM18020 Maintain hydraulic system components should also be selected.

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