Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to diagnose and repair faults in the mechanical connections fitted to both heavy vehicles and trailers. 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 mechanical connections include those in agricultural machinery, heavy commercial vehicles, trailers over 4.5 tonnes or mobile plant machinery.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 mechanical connections of heavy vehicles and trailers 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 mechanical connection specifications

two different heavy vehicle and trailer mechanical connections with faults

lubricating equipment for mechanical connections of heavy vehicles and trailers

tools, equipment and materials appropriate for repairing and adjusting mechanical connections of heavy vehicles and trailers.
