Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to return carburettor fuel system components to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the carburettor fuel system components, carrying out the overhaul procedures, reassembling and testing the carburettor fuel system components, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The carburettor fuel systems include those in vehicles from all sectors of the industry.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 carburettor fuel system components 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:

mechanical repair workplace or simulated workplace

workplace instructions

manufacturer carburettor fuel system component specifications

carburettor fuel system components specified in the performance evidence and requiring overhaul

tools, equipment and materials appropriate for overhauling and adjusting carburettor fuel system components.
