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 safe operating procedures for engine component rebuild machinery from workshop literature and signs.

Writing skills to:
  • legibly and accurately fill out workplace documentation to record measurements.

Numeracy skills to:
  • interpret numerical information in manufacturer specifications, workshop literature, and machinery dials, gauges and computer readouts
  • use basic mathematical operations, including addition and subtraction, to:
  • convert metric dimensions to imperial, and imperial dimensions to metric
  • calculate tolerances and clearances.

Planning and organising skills to:
  • select best heating, straightening and reclamation options for the work and sequence procedure to reduce time and material wastage.

Technology skills to:
  • use precision metric and imperial measuring 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:
  • selecting and using personal protective equipment (PPE)
  • using heating torches, ovens, presses and straightening tools
  • environmental requirements, including procedures for trapping, storing and disposing of cooling and lubricating fluids released during the machining process.

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:

  • heat treat, straighten and machine three different engine components, including one engine cylinder head.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

  • work health and safety (WHS) and occupational health and safety (OHS) requirements relating to heat treating, straightening and reclaiming engine components, including procedures for:
  • selecting and using personal protective equipment (PPE)
  • using heating torches, ovens, presses and straightening tools
  • environmental requirements, including procedures for trapping, storing and disposing of cooling and lubricating fluids released during the machining process
  • types, characteristics, uses and limitations of reclamation techniques, including:
  • heat treatment techniques, including:
  • effects of heat on different metals and heating procedures
  • hardening and tempering techniques, including thermal stress relieving to stabilise crankshafts and applying Tufftride and nitride
  • straightening techniques, including:
  • cylinder head straightening
  • crankshaft, camshaft and connecting rod straightening
  • machining surfaces to achieve tolerances and required finish
  • requirements of Australian standards relevant to engine reconditioning, including:
  • AS 4182 Automotive repairs – Code of practice for reconditioning reciprocating spark ignition engines
  • AS 4427 Automotive repairs – Code of practice for reconditioning reciprocating compression ignition engines
  • post-repair procedures, including component surface oxidation protection.

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 engine components that they have heat treated, straightened and reclaimed, 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 engine specifications
  • AS 4182 Automotive repairs – Code of practice for reconditioning reciprocating spark ignition engines
  • AS 4427 Automotive repairs – Code of practice for reconditioning reciprocating compression ignition engines
  • three different engine components, including one engine cylinder head
  • heating equipment and tools for heat treating, straightening and reclaiming engine components.
