Maintain hydraulic system components
Assessment tool
Version 1.0
Issue Date: May 2024
Hydraulic system components are identified, inspected and assessed using fluid power principles to predetermined specifications interpreted from data sheets and circuits diagrams.
Work is undertaken using predetermined standards of safety, quality and work procedures. Repairs and replacements are undertaken to site or manufacturers' specifications. Correct operational function of equipment components is confirmed and commissioned in conformance to specifications, using standard operating procedures.
For straightforward removals/replacement of components from a hydraulic system, Unit MEM18055B (Dismantle replace and assemble engineering components) or Unit MEM18071B (Connect/disconnect fluid conveying system components) should be regarded as sufficient.
Band: A
Unit Weight: 4
This unit covers checking hydraulic system components, and identifying and repairing or replacing faulty components.

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to maintain hydraulic system components. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with maintaining hydraulic system components or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: inspecting a range of hydraulic system components in accordance with standard operating procedures reading, interpreting and following relevant data sheets, specifications, hydraulic circuits, drawings, instructions and manuals checking the individual components within the hydraulic system for correct operation dismantling and rectifying faulty system components to manufacturers'/site specifications in accordance with standard operating procedures where appropriate, selecting replacement parts from the manufacturers'/suppliers' catalogues reassembling and testing the hydraulic system components checking the operation of the hydraulic system for conformance to specification checking repaired/replaced hydraulic system components for correct operation completing service reports where appropriate |
Required knowledge |
Look for evidence that confirms knowledge of: the full range of hydraulic system components characteristics and operational function of each hydraulic system component procedures for inspecting and testing hydraulic system components equipment required to test hydraulic system components specifications of each hydraulic system component hydraulic components not operating in accordance with specifications reasons for hydraulic components not operating in accordance with specification individual components within the hydraulic system safety procedures to be followed when working on hydraulic components where appropriate, faulty system components procedure for repairing hydraulic system components parts to be replaced reasons for replacing the parts identified the correct operation of the hydraulic system procedures for checking hydraulic system operation where appropriate, the follow-up procedures with respect to repaired/replaced hydraulic system components reporting/recording procedures reasons for completing service reports for hydraulic system components repaired/replaced hazards associated with maintaining hydraulic system components, including housekeeping safe work practices and procedures |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Hydraulic system components | Hydraulic system components may include static and dynamic seals, linear and semi-rotary actuators, fixed displacement and variable displacement pumps, pressure control valves, directional control valves, flow control valves, hydraulic motors, reservoirs, contamination control components (filtration), fluid conductors/fittings and other associated equipment. |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
