This unit of competency defines the skills and knowledge required to diagnose, locate faults, repair, overhaul, fit and adjust mechanical systems and equipment.

It integrates the application of prerequisite diagnostic, maintenance and overhaul competencies and applies to situations where an integrated level of skills in maintenance and overhaul of mechanical systems and equipment is required.

Where gland packing is required, unit MEM18013 Perform gland packing should also be selected.

Where additional specialist skills are required select appropriate units.

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