Application
This unit describes the performance outcomes required to remove and install engine assemblies fitted to heavy vehicles. It involves preparing for the task, removing and installing the engine assembly, performing post-installation testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The heavy vehicle engines include those of agricultural machinery, heavy commercial vehicles, marine vessels or mobile plant machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

isolating and stabilising vehicle or machinery
using vehicle or machinery lifting devices and supporting equipment’
working with compression ignition engines
environmental requirements, including procedures for trapping, storing and disposing of oils, fluids, coolants and gases released during removal and installation of engine assemblies
methods of disconnecting and reconnecting related systems, including:
air conditioning system
cooling system
electrical systems
exhaust system
fuel system
power steering system
hydraulic system
transmission systems, including:

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 heavy vehicle engine assemblies that they have removed and installed, 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
two different heavy vehicles requiring removal and installation of engine assemblies
tools, equipment and materials appropriate for removing and replacing heavy vehicle engines, including engine lifting devices and supporting equipment.
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 engine removal and installation specifications and procedures. |
Writing skills to: | legibly and accurately fill out workplace documentation when recording parts and material used. |
Oral communication skills to: | clarify workplace instructions and determine job requirements. |
Numeracy skills to: | measure components and use basic mathematical operations, including addition, subtraction, multiplication and division, to calculate distances, tolerances and deviations from manufacturer specifications calculate and adjust lubricant and coolant volumes. |
Planning and organising skills to: | plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes. |
