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.


For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

  • following work instructions, standard operating procedures (SOPs) and safe work practices;
  • identifying and interpreting specifications, charts, lists and drawings to maintain and overhaul mechanical equipment;
  • performing maintenance tasks on mechanical equipment, components or sub-assemblies in accordance with procedures;
  • assessing mechanical equipment, components and sub-assemblies visually and with appropriate test equipment to ensure correct function or determine malfunction and make adjustments according to procedures;
  • diagnosing and locating faults using appropriate diagnostic techniques, including visual inspection and use of test equipment, and localising fault condition to component level;
  • repairing or overhauling faulty equipment using appropriate fitting techniques and principles, tools, equipment and procedures and to manufacturers’ or site specifications;
  • fitting and adjusting mechanical systems and equipment by applying sound fitting principles and techniques to specifications, and;
  • performing final adjustments and testing mechanical equipment for accuracy and correct function to align with operational specifications and return to service in accordance with work site procedures.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
