What an assessment for AURTTM004 must cover

30 assessable components: 4 elements (16 performance criteria), 2 performance evidence and 6 knowledge evidence requirements, plus 6 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare to assemble engine block and sub-assembly

1.1Job requirements are determined from workplace instructions
1.2Information is sourced, procedures and methods are analysed, and appropriate tools are selected for assembling engine block and sub-assemblies
1.3Tools and measuring equipment are prepared and checked for serviceability
1.4Hazards associated with the work are identified and risks are managed
1.5Pre-assembly cleaning of engine components is carried out according to safety and environmental requirements, and components are laid out in logical order
1.6Replacement component parts are checked for size and suitability according to manufacturer specifications and job requirements

2 Check engine block and sub-assembly clearances and tolerances

2.1Clearances and tolerances are measured to the tolerance required by manufacturer specifications
2.2Clearances and tolerances are adjusted according to workplace procedures and to the tolerance required by manufacturer specifications

3 Assemble engine block and engine sub-assembly

3.1Engine sub-assemblies are assembled in correct order and without damage, against manufacturer specifications and tolerances and according to workplace procedures and relevant Australian standards and safety requirements
3.2Engine blocks are assembled in correct order against manufacturer specifications and tolerances and according to workplace procedures, relevant Australian standards, and safety requirements, and without causing damage to components or systems
3.3Assembled components are measured according to manufacturer specifications and workplace procedures
3.4Assembled component clearances and tolerances are adjusted according to workplace procedures and to the tolerance required by manufacturer specifications

4 Complete assembly process

4.1Final inspection is made to ensure finished work complies with workplace requirements
4.2Bright surfaces are treated with rust prevention solution and engine block and sub-assemblies are prepared for further process or storage according to workplace procedures
4.3Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
4.4Workplace documentation is processed according to workplace procedures

Performance evidence

assemble two different engine blocks, one of which must be a V configuration engine block, and the sub-assemblies of those engine blocks, in which the work must involve: a multi-cylinder diesel engine
a multi-cylinder petrol engine

Knowledge evidence

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to assembling engine blocks and sub-assemblies, including procedures for: selecting and using personal protective equipment (PPE) for handling engine blocks and sub-assemblies and using chemical cleaning agents; correctly operating specialised equipment, including heating torches, ovens and presses; handling freezing substances, including liquid nitrogen; manual handling techniques, including: using machinery for lifting engine blocks and engine components; using slings, chains and other lifting equipment according to safe work practices
environmental requirements, including procedures for trapping, storing and disposing of cleaning fluids released during the assembly process
procedures for clearance testing and adjusting or machining components, including: piston to connecting rod big end alignment; big end and main bearing crush with bearing blue; piston ring end gap, back clearance and side clearance; bearing to crankshaft clearances with plastigage and measuring and calculating clearances; semi-flanged thrust bearings; finished camshaft bearings and measuring clearances; camshafts and cam followers; camshaft end float; crankshaft end float; gear backlash; oil pump sealing and pick-up oil piping
component assembly procedures and processes, including: pre-assembly wash procedures for components; welsh plugs and oil gallery plugs; piston and connecting rod assemblies; big end bearings; piston rings to pistons, including procedures for using ring compressors; main bearings and thrust washers; semi-flanged thrust bearings; crankshafts, including protection measures for crankshaft journals, bearings, rings and bores; finished camshaft bearings; camshafts and cam followers; timing gears; chains and tensioners; oil pumps, oil squirters and oil pump pick-ups; balance shafts
fitting ancillary components, including: covers and seals; housings; diesel fuel injection pumps; oil coolers; crankshaft pulleys; flywheels; bell housings
requirements of Australian standards relevant to engine reconditioning, including: AS 4182 Automotive repairs – Code of practice for reconditioning reciprocating spark ignition engines; AS 4427 Automotive repairs – Code of practice for reconditioning reciprocating compression ignition engines.

Questions about assessing AURTTM004

What does an assessment tool for AURTTM004 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTM004 needs to address all 30 unit components: 4 elements with 16 performance criteria, 2 performance evidence requirements, 6 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AURTTM004?

Auditori pulls the current release of AURTTM004 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AURTTM004 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTM004 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AURTTM004, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
