What an assessment for MEM27019 must cover

52 assessable components: 6 elements (25 performance criteria), 10 performance evidence and 17 knowledge evidence requirements. 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 Determine job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from specifications, drawings, job sheets or work instructions

2 Check engine performance

2.1Determine normal engine performance parameters from manufacturer specifications and workplace records
2.2Perform appropriate diagnostic tests for engine and equipment type
2.3Identify faults from diagnostic test results
2.4Determine appropriate action to rectify faults

3 Remove engine and engine assemblies

3.1Remove engine and ancillary components according to manufacturer specifications, workplace procedures and WHS and environmental requirements
3.2Tag and record engine and ancillary components according to workplace procedures
3.3Prepare engine and engine assemblies for repair

4 Repair engines

4.1Interpret characteristics of surface finishes and wear patterns on top and bottom end components
4.2Assess components for abnormal wear or defects
4.3Remove top-end components and dismantle block assembly according to manufacturer recommendations
4.4Select appropriate cleaning solution and procedure, clean and store components not requiring repair ready for reassembly
4.5Replace or repair faulty parts to manufacturer specification
4.6Test engine and make any required post-repair adjustments

5 Install repaired or replacement engine

5.1Locate and fix engine according to manufacturer specifications
5.2Refit ancillary components and equipment systems
5.3Check and adjust lubricants, coolant, fuel and other required fluids
5.4Test engine and make any required post-installation adjustments

6 Undertake completion tasks

6.1Clean work area and dispose of non-recyclable material according to workplace and environmental requirements
6.2Collect and store recyclable material in appropriate containers
6.3Check and store tools and equipment
6.4Document and report engine repair or replacement according to workplace procedures

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, charts, lists, drawings and other applicable reference documents to perform engine repair or replacement
checking engine for conformance and removing the engine and top-end components and dismantling block assembly
undertaking calculation and numerical operations to calculate bearing clearances
checking parts for abnormal wear or defects and identifying components for reuse or replacement
testing of cylinder head, spring tensions, valves and guides for conformance to specifications
replacement of worn or faulty parts
cleaning parts using appropriate solutions and safety precautions and rack and setting out engine parts according to their original position in readiness for reassembly
obtaining and recording measurements and interpreting readings for replacement or reuse as being under or over size
reassembling engine bottom-end components using appropriate tools, equipment and techniques.

Questions about assessing MEM27019

What does an assessment tool for MEM27019 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM27019 needs to address all 52 unit components: 6 elements with 25 performance criteria, 10 performance evidence requirements, 17 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 MEM27019?

Auditori pulls the current release of MEM27019 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 MEM27019 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM27019 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 MEM27019, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
