Equivalencies: This unit of competence incorporates units 18.12A of the National
Metal and Engineering Competency Standards
Complex/specialised seals may include generator hydrogen seals, double acting mechanical seals, floating seals and turbine labyrinth glands
Test equipment may include feeler gauge, dial gauge, bearing blue, micrometers, flexi gauge, leads and go/no-go gauges
Tools and equipment may include micrometers, verniers, dial test indicators, slip gauges, hand tools, customised mandrels, digital height gauges, internal micrometers, oxyacetylene gear, depth gauges, air grinders, jigs and fixtures, customised spanners, electronic internal micrometers, appropriate lifting devices, heated oil bath and induction heaters
Details of maintenance may be clarified by diagnosis and work place inspection
Maintenance may include repair, inspection, modification, overhaul, lubrication, servicing and test running
Work completion details may include plant/maintenance records, job cards, check sheets, on device labelling updates and reporting/documenting equipment defects
Work site environment may be affected by nearby plant or processes, e.g. chemical, heat, dust, noise, gas and oil
Isolations can refer to electrical/mechanical or other associated processes

Critical aspects of evidence
It is essential that competence is assessed in the critical aspects of:-
The knowledge and applicationof relevant sections of: occupational, health and safety legislation, statutory legislation, enterprise/site safety procedures and enterprise/site emergency procedures; preparation and planning of work; removal techniques; maintenance techniques and procedures; installation 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.
