This unit of competency defines the skills and knowledge required to test, fault find and rectify hydraulic systems used in the earthmoving, agricultural and transport industries.

It covers identifying the hydraulic system and components used on mobile plant, general servicing and identifying faults that are related to electronic and fieldbus controls and communication.

Where the rectification of electronic controls is required unit MEM27016 Diagnose and maintain electronic controlling systems on mobile and stationary plant should also be selected.

Where the rectification of communication systems is required unit MEM27018 test, diagnose and rectify mobile and stationary plant external monitoring and control systems should also be selected.

Where the rectification of fieldbus controls is required unit MEM27023 Diagnose and rectify fieldbus circuits in mobile and stationary plant and equipment should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Band: A

Unit Weight: 4

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the 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.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
General servicing includes the following:	fluid replacement filtration requirements oil sampling checking for and rectifying faults preventative maintenance checks and adjustments to suit changes in operating conditions
Hydraulic systems include the following:	open circuit closed circuit systems used for one (1) or more of the following: direct motive power powering actuators braking transmissions and gearboxes pumping
Contaminants include one (1) or more of the following:	dirt metal particles other particulates water fuel non-hydraulic oil
Rectifying includes the following:	replacement of components and fittings filtering or replacement of hydraulic fluid assembly and fitting of hydraulic hoses flushing/cleaning of tubing and pipework resealing and repairs to cylinders and rams resetting of controls
Checks include one (1) or more of the following:	pressure and flow testing cycle times basic interrogation of diagnostic system controllers basic electronic servicing
Components include one (1) or more of the following:	actuators fixed and variable displacement pumps pressure, directional and flow control valves electro-hydraulic servo and servo-proportional valve (EHSV) hydraulic motors reservoirs contamination control components (filtration) fluid conductors/fittings other associated equipment
Service of hydraulic systemsinclude the following:	change out of hydraulic components, including: pumps valves actuators the associated remedial actions required, including: system flushing and purging setting of component parameters

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.
