AURTTX004 Inspect and service hydrostatic transmissions
Assessment tool
Version 1.0 Issue Date: May 2024
This unit describes the performance outcomes required to inspect and service hydrostatic transmissions and associated components. It involves preparing for the task, inspecting the transmission and components, reporting the inspection findings, servicing and adjusting the transmission, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The hydrostatic transmissions include those of agricultural machinery, mobile plant machinery or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

3.1 Service and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems
3.2 Post-service testing is carried out according to workplace procedures
4. Complete work processes
4.1 Final inspection is made to ensure work is to workplace expectations and machinery is presented ready for use
4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
4.3 Tools and equipment are checked and stored according to workplace procedures
4.4 Workplace documentation is processed according to workplace procedures
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:
inspect and service the hydrostatic transmissions of two different machinery.
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to inspecting and servicing hydrostatic transmissions, including procedures for:
working with high oil pressures
working with stored hydraulic accumulator pressures
isolating and stabilising machinery
environmental requirements, including procedures for trapping, storing and disposing of oil released from hydrostatic transmissions
identification, function and basic operation of hydrostatic transmission and components, including:
charge pump
main pump
drive motor
filters
hydraulic lines
heat exchanger
reservoir
control valve
types and applications of hydraulic oil
inspection procedures for hydrostatic transmissions, including:
hydraulic oil sampling
oil leaks
pressure checks as required
service and adjustment procedures for hydrostatic transmissions, including
adjusting or replenishing oil level as required
replacing filters as required
post-service testing procedures for hydrostatic transmissions.
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 hydrostatic transmissions 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
two different machinery with hydrostatic transmissions requiring servicing
tools, equipment and materials appropriate for inspecting and servicing hydrostatic transmissions.
