Application

This unit of competency defines the skills and knowledge required to recondition and reinstall fuel system components on large stationary or mobile diesel engines.

It includes removal and cleaning of fuel system components, assessing components for wear and defects, deciding whether a component should be reconditioned or replaced, reinstallation of reconditioned components in engines and testing of reconditioned components for effective operation.

Where breakdown testing and repair of compression ignition systems is required, unit MEM27002 Test and repair compression ignition systems should also be selected.

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

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications, charts, lists, drawings and service documents for overhauling engine fuel system components

dismantling the engine fuel system components using specialised tools and test equipment and checking parts visually for abnormal wear or defects

identifying parts according to their original location in the pump/injector and protecting and storing them as required for reassembly

undertaking calculations and numerical operations for overhauling engine fuel system components

measuring and recording fuel system components using appropriate measuring equipment

assessing components and parts for serviceability or replacement

reconditioning, assembling and replacing components according to manufacturer specifications

testing operation of reconditioned components to specifications.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

sequence for disassembling engine fuel components

specialised tools required and their application

common defects, examples and causes of abnormal wear

characteristics of surface finishes and wear patterns for fuel system components

method of cleaning fuel system components

appropriate solvents for cleaning fuel systems

procedures for:

cleaning, protecting and storing fuel system components

marking fuel system components in readiness for reassembly

recording fuel system component measurements

reconditioning and/or replacing faulty fuel system components

assembling and testing fuel system components

setting fuel system components

measuring instruments to be used to measure fuel system components and reasons for selecting the chosen measuring instruments

principles of operation of diesel fuel systems

specifications of the fuel system components

tools, techniques and equipment required to carry out fuel system component tests.

Assessment Conditions

Assessors must:

have vocational competency in overhauling engine fuel system components at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
