New unit of competency.

Application

This unit describes the performance outcomes required to diagnose and repair faults in the final drive assemblies of mobile plant. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry. The final drive assemblies include those in agricultural machinery or mobile plant machinery.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Elements and Performance Criteria

Elements 

Elements describe the essential outcomes.

Performance Criteria 

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Prepare to diagnose and repair mobile plant final drive assembly

1.1 Job requirements are determined from workplace instructions

1.2 Diagnostic information is sourced and interpreted

1.3 Diagnostic options are analysed and those most appropriate to the circumstances are selected

1.4 Hazards associated with the work are identified and risks are managed

1.5 Diagnostic tools and equipment are selected and checked for serviceability

2. Diagnose final drive assembly

2.1 Diagnostic tests are carried out according to manufacturer specifications, workplace procedures, and environmental and safety requirements 

2.2 Faults are identified from diagnostic test results and causes of faults are determined

2.3 Diagnosis findings, including recommendations for necessary repairs or adjustments, are reported according to workplace procedures

3. Repair final drive assembly

3.1 Repair information  is sourced and interpreted

3.2 Repair options are analysed and those most appropriate to the circumstances are selected

3.3 Repair tools, equipment and materials are selected and checked according to manufacturer procedures

3.4 Repairs and component replacements and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements , and without causing damage to components or systems

3.5 Post-repair testing is carried out according to workplace procedures to confirm fault rectification, and any further problems detected as having been introduced during the repair process are rectified

4. Complete work processes

4.1 Final inspection is made to ensure work is to workplace expectations and machinery is presented ready for use

4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected

4.3 Tools and equipment are checked and stored according to workplace procedures

4.4 Workplace documentation is processed according to workplace procedures

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills 

Description 

Learning skills to:
  • locate appropriate sources of information efficiently.

Reading skills to:
  • interpret information from manufacturer and workshop literature when seeking final drive assembly specifications and procedures.

Writing skills to:
  • legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used.

Oral communication skills to:
  • clarify instructions
  • report diagnostic findings and make repair recommendations.

Numeracy skills to:
  • measure final drive assembly components and use basic mathematical operations, including addition, subtraction, multiplication and division, to calculate distances, tolerances and deviations from manufacturer specifications
  • calculate gear ratios and torque reduction and multiplication.

Planning and organising skills to:
  • plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.

Technology skills to:
  • use precision measuring equipment, such as micrometers and dial indicator gauges.

Range of Conditions

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety requirements  must include:
  • work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for isolating and stabilising machines.

Repair information  must include procedures relating to:
  • removing and replacing final drive assemblies
  • dismantling, repairing, reassembling and adjusting final drive assemblies.

Environmental requirements  must include:
  • procedures for trapping, storing and disposing of oils and fluids released from final drive assemblies.

Release 1 

New unit of competency.

Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

  • diagnose and repair faults in two mobile plant final drive assemblies as follows:
  • one differential carrier assembly
  • one of the following final drive assemblies:
  • double reduction
  • planetary final drive
  • chain drive.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

  • work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing mobile plant final drive assemblies, including procedures for isolating and stabilising machines
  • environmental requirements, including procedures for trapping, storing and disposing of oils and fluids released from final drive assemblies
  • operating principles of mobile plant final drive assemblies and their:
  • final drive gears, including:
  • gear types and specific lubrication requirements
  • gear ratios and torque reduction and multiplication
  • differential function
  • chain drives
  • application, purpose and operation of mobile plant final drive assemblies and components, including:
  • differential carrier
  • limited slip, no-spin and differential lock
  • double reduction
  • planetary final drive
  • chain drive
  • diagnostic testing procedures for mobile plant final drive assemblies, including:
  • sources of fluid leaks

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the mobile plant final drive assemblies that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • workplace instructions
  • manufacturer mobile plant final drive assembly specifications
  • two different mobile plant with the final drive assemblies specified in the performance evidence
  • diagnostic equipment for mobile plant final drive assemblies
  • tools, equipment and materials appropriate for repairing and adjusting mobile plant final drive assemblies.
