Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence incorporates unit 18.9A of the National Metal
and Engineering Competency Standards
Advanced alignment may include concentricity and ovality checks and adjustments, offsets and thermal expansion checks and adjustments, pre-load centralising and adjustments to within tenths of a thousandth of one inch
Advanced/complex alignment typically would be of three or more components
Equipment and tools may include bearings, couplings, seals, hydraulic tools, rigging equipment, measuring instruments, optical levels, laser levels, electronic levels, slip gauges, dumpy levels and other associated levelling and aligning equipment
Plant and machines may include turbine rotor and boiler feed pumps
Work completion details may include plant and maintenance records, job cards and check sheets updating
Work site environment may be affected by nearby plant or process, eg, heat, noise, dust, oil, water, chemical
Isolations can refer to electrical or process

Critical aspects of evidence
It is essential that competence is assessed in the critical aspects of: the knowledge and application ofrelevant sections of occupational, health and safety legislation, statutory legislation, enterprise/site safety procedures and enterprise/site emergency procedures; preparation and planning of work; using precision measuring equipment; applying levelling and aligning principles; calculating and applying correct adjustment techniques; completion of work procedures
Context of assessment
Competency Standards should be assessed in the workplace or simulatedworkplace 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.
