Unit of Competency MEM18006B - Repair and fit engineering components
Description This unit covers fault finding, repairing faulty components, manufacturing new parts/components, and fitting mechanical engineering components into assemblies or sub-assemblies.Tasks undertaken use mechanical engineering and maintenance principles, designated procedures, correct and appropriate tools/equipment, and safe working practices.
Employability Skills
Learning Outcomes and Application Work is undertaken autonomously or in a team environment using predetermined standards of quality, safety and workshop procedures. This unit includes the repair, replacement, assembling and final fitting of items, sub-assemblies and assemblies. All specifications are interpreted from engineering drawings, detailed/technical sketches and associated data sheets; this includes the use of acceptable workshop practices. New components are manufactured as required to specifications.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package

Overview of assessment requirements

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

Context of 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.

Interdependent assessment

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with repairing and fitting 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.

Consistency of performance

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.

Required skills

Look for evidence that confirms skills in:

obtaining operational specifications for the component/s

assessing operation against specification and identifying faults

checking component/s visually and dimensionally against the operational specifications using work site procedures

checking repaired components visually and dimensionally for conformance to specifications

adjusting components to achieve conformance to specifications where appropriate

selecting replacement parts which conform to specifications

preparing and assembling components using appropriate fitting techniques and principles

where appropriate, applying gland packing, jointing or gasket materials, using acceptable engineering practices

applying appropriate lubricants to the assembly using acceptable engineering practices, where required

checking components for conformance to specification

where appropriate, adjusting components to achieve conformance to specifications

where appropriate, recording any approved modifications/alterations to work site procedures

inspecting the final assembly and checking conformance to operational specifications

where appropriate returning the final assembly to service in accordance with work site procedures

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

tools and equipment to be used to dismantle the components

consequences of having components that do not comply with operational specifications

the types of adjustment applicable to the components being repaired/fitted

appropriate methods of repair

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

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

the material properties required

the manufacturing operations to be used in the production of new components

the sequence of operations to be used in the production of new components

the fitting requirements for assembling components

the appropriate sequence of assembly tasks

the purpose of using gland packing, jointing or gasket materials

the reasons for selecting particular jointing or packing materials

the applications of different types of lubricants

the consequences of using inappropriate or no lubricant

the need to have approval for out of specification modifications

the reasons for documenting out of specification modifications

return to service procedures

the consequences of not following work site return to service procedures

hazard and control measures associated with repairing and fitting engineering components, including housekeeping

safe work practices and procedures

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here.

The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable

Variable

Scope

Manufacturers' catalogue

Any appropriate manufacturers' catalogues that contain replacement parts that conform with specifications and operational requirements

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
