Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Assess drive line and final drive operation

1.1. Universal and constant velocity joints, conventional/limited slip and locking, differential action and conventional/swing axle operating principles are understood.

1.2. Relevant information is obtained and correctly interpreted prior to any testing.

1.3. Preliminary checks are undertaken safely and to prescribed procedures.

1.4. Faults are correctly isolated to component level and appropriate corrective action is determined.

1.5. Test equipment is adapted and used correctly.

1.6. Component parts are correctly assessed for reuse or replacement.

2. Repair/replace faulty components

2.1. Component wear and clearances are correctly determined using appropriate test equipment and manufacturers' recommendations.

2.2. Replacement components are correctly selected using manufacturers' data.

2.3. Components are removed and refitted to driveline and final drive assemblies following prescribed procedures.

2.4. Adjustments are made correctly using appropriate tooling/equipment and manufacturers' data.

2.5. Test and repair/replacement activities are accurately recorded.

2.6. Drive line and final drive assemblies are free of excessive noise and operate to specification after work is carried out.

Evidence Guide

EVIDENCE GUIDE 

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 diagnose and rectify drive line and final drives. 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 testing and diagnosing drive line and final drives, 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 

Range Statement

RANGE STATEMENT 

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.
