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.

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; - assessing engineering components visually and dimensionally with appropriate testing and measuring equipment techniques for compliance to specifications; - repairing or replacing faulty components using appropriate tools, equipment and techniques; - assembling components using appropriate fitting techniques and principles; - recording approved modifications/alterations; - inspecting final assembly to check compliance to specifications, and; - returning the final assembly to service in accordance with SOPs.Students will also be expected to demonstrate the following knowledge: - safe work practices and procedures and use of personal protective equipment (PPE); - tools and equipment used to dismantle, repair, assemble and fit engineering components; - consequences of having non-compliant components; - types of modifications/adjustments to components being repaired/fitted; - repair methods; - sources of replacement parts; - techniques for the production of engineering components; - assembly and fitting techniques; - machine backlash/recoil; - measuring equipment; - engineering components - shafts, single and multi-throw crankshafts, cams and journals, bearings and bearing surfaces, and keys; - squareness, roundness, concentricity, flatness, straightness, surface finish and angular correctness; - purpose, selection criteria and use of gland packing, jointing or gasket materials; - types and application of lubricants; - approval processes for documenting out-of-specification modifications, and; - commissioning and return to service procedures.
