New unit of competency.

Application

This unit describes the performance outcomes required to return starting system motors to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the transmission, carrying out the overhaul process, reassembling and testing the transmission, and completing workplace processes and documentation.

It applies to those working in an automotive service and repair industry. The starting system motors include those fitted to agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycles or outdoor power equipment.

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

4.3 Assembly of starter motor is completed within workplace timeframes and without causing damage to other components or systems

4.4 Post-assembly testing is carried out according to workplace procedures and safety and environmental requirements, and any problems detected as having been introduced during the assembly process are rectified

5. Complete work processes

5.1 Final inspection is made to ensure work is to workplace expectations and starter motor is presented ready for use or storage

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

5.3 Tools and equipment are checked and stored, and any faulty electrical equipment is identified, tagged and isolated according to workplace procedures

5.4 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 sources of information relevant to starting system motor efficiently.

Reading skills to:
  • interpret and assess information from manufacturer and workshop literature when seeking starting system motor 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 evaluation findings and make overhaul recommendations.

Numeracy skills to:
  • measure starting system motor components and use basic mathematical operations, including addition and subtraction, to calculate tolerances and deviations from manufacturer specifications.

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

Technology skills to:
  • use precision measuring equipment, such as vernier calipers and micrometers
  • use specialised starting system motor overhaul equipment.

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 and environmental requirements  must include:
  • work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for:
  • using specialised tools and equipment
  • using appropriate personal protective equipment (PPE)
  • identifying hazards and controlling risks associated with wearing jewellery while working around high current wiring systems
  • environmental requirements, including procedures:
  • found in safety data sheets (SDS) relating to toxic and corrosive substances
  • for disposing of replaced components.

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:

  • overhaul the starting system motors of three different vehicles, vessels or machinery, which must include:
  • one direct drive starter motor
  • one of the following solenoid pre-engaged types of starter motors:
  • direct drive
  • reduction drive
  • one stop-start starter motor.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

  • work health and safety (WHS) and occupational health and safety (OHS) requirements relating to overhauling starting system motor, including procedures for:
  • using specialised tools and equipment
  • using appropriate personal protective equipment (PPE)
  • identifying hazards and controlling risks associated with wearing jewellery while working around high current wiring systems
  • environmental requirements, including procedures:
  • found in safety data sheets (SDS) relating to toxic and corrosive substances
  • for disposing of replaced components
  • types, characteristics and operating principles of vehicle, vessel or machinery starting system motors, including starter motors that are direct drive and solenoid pre-engaged types

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 starting system motors 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 starting system motor specifications
  • three different vehicles, vessels or machinery with the starting system components specified in the performance evidence and requiring overhaul
  • tools, equipment and materials appropriate for overhauling and adjusting a range of starting system motors.
