Application
This unit describes the performance outcomes required to inspect, service and repair faults in track type drive and support systems. It involves preparing for the task, inspecting the system to determine the service and repair requirements, carrying out the service and repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The track type drive and support systems include those of agricultural machinery or mobile plant machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

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 track type drive and support systems that they have serviced and repaired, 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 track type drive specifications
machinery with track type drive and support system requiring service and repair
track drive system inspection and measurement tools and gauges, including:
track chain, track link, pin, bushing and track shoe
undercarriage tensioner, roller, idler and drive sprocket
tools, equipment and materials appropriate for inspecting, servicing, repairing and adjusting track type drive and support systems.
