Application
This unit describes the performance outcomes required to install hydraulic systems. It involves preparing for the task, installing and testing the operation of the hydraulic systems, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The hydraulic systems include those in agricultural machinery, heavy commercial vehicles or mobile plant machinery. Work involves installing hydraulic systems in vehicles or machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Prepare to install hydraulic system | 1.1 Job requirements are determined from workplace instructions 1.2 Hydraulic system installation procedures and information are sourced and interpreted 1.3 Installation options are analysed and those most appropriate to the circumstances are selected 1.4 Hazards associated with the work are identified and risks are managed 1.5 Tools, equipment and materials are selected and checked for serviceability |
2. Install hydraulic system | 2.1 System is checked for correct application and components are checked for damage 2.2 System is installed according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems 2.3 Installed system is tested for correct operation and required adjustments are made according to manufacturer specifications, workplace procedures, and safety and environmental requirements 2.4 System is re-tested in normal operating conditions and final adjustments are made |
3. Complete work processes | 3.1 Final inspection is made to ensure work is to workplace expectations and vehicle or system is presented ready for use, including ensuring that protective guards, safety features and cowlings are in place 3.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected 3.3 Tools and equipment are checked and stored according to workplace procedures 3.4 Workplace documentation is processed according to workplace procedures |

procedures for installing hydraulic systems in vehicles and machinery
procedures for adjusting, tuning and testing the installation of hydraulic systems in vehicles or machinery.
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 hydraulic systems that they have 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 hydraulic system specifications and installation procedures
hydraulic system for installation
one vehicle or machinery requiring installation of hydraulic system
AS 1101.1 Graphic symbols for general engineering, Part 1: Hydraulic and pneumatic systems
Mechanical Design Guideline (MDG) 41 Guideline for Fluid Power Safety at Mines
tools, equipment and materials appropriate for installing hydraulic systems.
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 information efficiently. |
Reading skills to: | interpret information from manufacturer and workshop literature when seeking hydraulic system specifications and procedures interpret hydraulic circuit installation procedures. |
Writing skills to: | legibly and accurately fill out workplace documentation when reporting work performed and recording parts and material used. |
Oral communication skills to: | clarify instructions report findings and make installation recommendations. |
Numeracy skills to: | measure hydraulic system components and use mathematical processes, including addition, subtraction, multiplication and division, to calculate distances, areas, volumes, tolerances and deviations from manufacturer specifications. |
Planning and organising skills to: | plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes. |
Technology skills to: | use precision measuring equipment, such as rulers, vernier calipers and hydraulic pressure gauges. |
