Description
This unit describes the performance outcomes required to use industry-accepted methods to apply metal spray, hard chrome and weld materials to rebuild components. It involves determining repair requirements and rebuilding engine components in an engine reconditioning process.No licensing, legislative, regulatory or certification requirements apply to this unit at time of endorsement.
Notes
Elements and Performance Criteria
1. Prepare to undertake metal building procedures
  • 1.1. Workplace instructions are used to determine job requirements, including method, process and equipment
  • 1.2. Information is sourced, procedures and methods are analysed, and appropriate tooling options are selected for rebuilding engine components
  • 1.3. Tools and measuring equipment are checked and prepared for operation
  • 1.4. Safe operating procedures and workplace health and safety (WHS) and environmental requirements are observed throughout the work
  • 1.5. Engine component is prepared for metal application
2. Apply metal to engine components
  • 2.1. Correct information is accessed and interpreted from manufacturer and component supplier specifications
  • 2.2. Metal application process is used to rebuild damaged engine components
  • 2.3. Rebuild method is completed in readiness for further repair without causing damage to components or system
3. Perform necessary machining to rebuild component
  • 3.1. Machining is carried out according to workplace procedures and without causing damage to component or system
  • 3.2. Component is checked and measured with instruments to ensure compliance with specifications
  • 3.3. Machining operations are completed to specifications
4. Finalise rebuild process
  • 4.1. Surfaces of component are finished to manufacturer and component supplier specifications and allowable tolerances
  • 4.2. Finishing work is completed without causing damage to the component
  • 4.3. Surfaces are protected with a rust prevention solution
  • 4.4. Components are prepared for further process or storage
  • 4.5. Workplace documentation is processed according to workplace procedures
Range Statement

Evidence Guide
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

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.
A person who demonstrates competency in this unit must be able to:
observe safety procedures and requirements
select methods and techniques for applying metal appropriate to the circumstances
complete preparatory activity in a systematic manner
rebuild a range of engine components according to workplace, manufacturer and component supplier requirements
complete work without damage to tools and equipment or injury to persons.
Context of, and specific resources for assessment
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting. Performance is demonstrated consistently over a period of time and in a suitable range of contexts.
Assessment is to occur:
using standard workplace practices and procedures
following safety requirements
applying environmental constraints.
Assessment is to comply with relevant:
regulatory requirements
Australian standards
industry codes of practice.
The following resources should be made available for the assessment of this unit:
appropriate worksite
crankshafts, camshafts, engine cylinder head assemblies, and engine block assemblies
material relevant to rebuilding engine components
equipment and hand and power tools appropriate to rebuilding engine components
specifications and work instructions.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required skills and knowledge.
Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure its correct interpretation and application.
Assessment must confirm that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Assessment processes and techniques must be culturally sensitive and appropriate to the language and literacy capacity of the candidate and the work being performed.
