Overview

This unit covers undertaking preventive maintenance
checks/adjustments on hydraulic systems, and fault finding,
repairing, rectifying or overhauling, and recommissioning
hydraulic systems.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

preparing hydraulic system components;
inspecting and testing the hydraulic system/components;
performing scheduled preventative maintenance tasks;
performing obvious repairs on the hydraulic system/components;
visually inspect the hydraulic system and its components;
consulting with the system operator;
obtaining and interpreting maintenance reports;
using appropriate test equipment and techniques;
verifying apparent faults/malfunctions;
documenting or reporting all verified faults/malfunctions;
initiating the repair/overhaul of the hydraulic system;
isolating and depressurising the hydraulic system;
tagging the isolated hydraulic system;
removing the hydraulic components/sub-assembly from the system;
dismantling the hydraulic components/sub-assemblies;
examining the hydraulic components/sub-assemblies;
selecting replacement parts from manufacturers' catalogues;
repairing/replacing/overhauling faulty items;
refitting the hydraulic component/sub-assembly into the system;
testing the hydraulic component/sub-assembly;
recommissioning the hydraulic system/sub-assembly;
checking/testing the hydraulic system/sub-assembly;
where appropriate, initiating follow-up procedures, and;
updating and completing all maintenance records/reports.

Students will also be expected to demonstrate the following knowledge:

common hydraulic system components;
hydraulic system/component faults that can be determined by visual inspection;
the application of common hydraulic system/component test equipment;
schedule of preventative maintenance tasks;
the manufacturers' specifications;
common hydraulic system and component faults;
any previous faults in the hydraulic system/components;
any previous maintenance carried out on the hydraulic system/components;
typical checks/tests that can be carried out on hydraulic systems/components and their application;
hydraulic system/component test and testing techniques;
apparent faults/malfunctions;
the documentation/reporting requirements with respect to verified faults/malfunctions;
the procedures for initiating repair/replacement and/or overhaul of the hydraulic system;
the hazards and control measures associated with working on hydraulic systems/components;
the procedures for isolating and depressurising hydraulic systems;
tagging requirements for isolated systems;
the structure of typical hydraulic components;
the specifications of hydraulic components and their constituent parts;
the appropriate repair/overhaul procedures;
system recommissioning procedures;
the hydraulic system operational specifications;
any appropriate follow-up maintenance or operational checks;
the maintenance recording/reporting requirements;
the consequences of inaccurate or incomplete recording/reporting of maintenance/service activities, and;
safe work practices and procedures.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
