Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence incorporates unit 18.6a of the National Metal and
Engineering Competency Standard
Details of maintenance may be clarified by diagnosis and/or workplace inspection
Maintenance may include refurbishment/replacement of bearings (plain, white meal, anti-friction), seals (hydrogen, labyrinth), complex seals, couplings, coolers, pipe work, barring gear, inspection, lubrication and test running
Generator maintenance may require the removal of the rotor and subsequent replacement would involve complex levelling and alignment techniques
Precision measuring equipment may include inside/outside micrometers and verniers, dial gauges, depth gauges, slip gauges and feeler gauges
Work completion details may include plant and maintenance records, job cards, check sheets and on device labelling updates.
Worksite environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water and chemical
Isolations can refer to electrical/mechanical or other associated processes

Critical aspects of evidence
The knowledge and application of relevant sections of: Occupational, health and safety legislation; Statutory legislation; Enterprise/site safety procedures; Enterprise/site emergency procedures
Preparation and planning of work
Performance assessment techniques
Removal techniques and procedures
Overhaul and maintenance techniques and procedures
Replacement techniques and procedures
Completion of work procedures
Context of assessment
Competency Standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions
Assessment of this unit will be supported with documentary evidence, by means of endorsement stating type and application of work
Interdependent assessment of unit
