The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to dismantle, replace and assemble engineering components. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with dismantling, replacing and assembling engineering components or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Required skills

Look for evidence that confirms skills in:

obtaining and interpreting all relevant instructions, standard operating procedures, drawings and specifications

preparing component for dismantling

dismantling components using appropriate techniques, tools and equipment

marking component parts appropriately for identification purposes

checking components visually and dimensionally for conformance to specification

where appropriate, marking faulty parts for repair, replacement or adjustment

selecting and confirming replacement parts to specifications

obtaining and using all relevant supplier catalogues

preparing and assembling components using appropriate techniques in accordance with standard operating procedures

where appropriate, applying lubricants correctly to the assembly in accordance with specifications and standard operating procedures

where appropriate, applying packing and/or sealing materials in accordance with specifications and standard operating procedures

inspecting and checking the final assembly for conformance to specification

where appropriate, returning the final assembly to use

Required knowledge

Look for evidence that confirms knowledge of:

tasks to be performed in accordance with standard operating procedures

procedures for dismantling the assembly

tools and equipment to be used to dismantle the components

procedures and required equipment for checking components for conformance to specification

specifications of the components to be replaced

features and/or dimensions upon which replacement parts are to be selected

process of identifying replacement parts from "third party" suppliers' catalogues

procedures for assembling components

requirements of the assembly in terms of specifications, operational performance, quality and safety

procedures for lubricating the assembly

materials

checks to be undertaken during inspection of the final assembly

procedures for returning components/assemblies into use

hazards and control measures associated with dismantling, replacing and assembling engineering components, including housekeeping

safe work practices and procedures

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Engineering components

Includes a range of component parts found in equipment or product assemblies, sub-assemblies, e.g. couplings, universal joints, pumps etc. employing shafts, pre-manufactured bearings and seals, lubricants, fasteners, gaskets etc.

Appropriate tools and equipment

Includes a range of hand and power tools, bearing pullers, special purpose dismantling and assembly tools etc.

Selected

Replacement parts are selected from manufacturers' catalogues, etc.

Appropriate techniques

Are in accordance with standard operating procedures and may include the straightforward removal and replacement of pre-manufactured bearings and seals
