workplace specifications and requirements
regulatory and legislative requirements relating to the automotive industry, including Australian Design Rules
safe work procedures relating to the operation of machinery associated with balancing engine components
verbal, written and graphical instructions, signage, work schedules, plans, specifications, work bulletins, memos, material safety data sheets (MSDS), diagrams or sketches.
Appropriate tooling options may include:
comparator gauges and ring compressors
hand tooling
plasti-gauge
power tooling
torque wrenches.
Tools and measuring equipment may include:
balancing equipment
balancing weights
scales.
WHS requirements may include:
individual state or territory regulatory requirements
operational risk assessment and treatments associated with:
electrical safety
machinery movement and operation
manual and mechanical lifting and shifting
toxic substances
working in proximity to others and site visitors
personal protective equipment (PPE) required by legislation, regulations, codes of practice and workplace policies and procedures.
Environmental requirements are to include:
clean-up management
dust and noise minimisation
waste management.
Preparation for balancing includes:
thoroughly cleaning all components
checking all components to ensure there is no further machining required.
Engine components to be balanced include:
crankshafts
flywheels
piston and connecting rod assemblies.
Balancing procedures of rotating engine components include:
using different machines to determine positions where material is to be removed or added
different methods of removing or adding weight to engine components, such as drilling, welding, machining and adding metal slugs.
Balancing procedures of reciprocating engine components include:
using different scales and associated equipment to measure the weight of the piston and connecting rod assembly.
different methods of removing or adding weight to piston and connecting rod assembly, such as drilling, welding, machining and adding metal slugs.

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
communicate effectively with others involved in or affected by the work
select methods and techniques to balance engine components appropriate to the circumstances
complete preparatory activity in a systematic manner
balance a range of crankshafts and components according to workplace, manufacturer and component supplier requirements
balance components within workplace timeframes
present components to customer according to workplace requirements.
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.
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 must be made available for the assessment of this unit:
workplace location or simulated workplace
material relevant to balancing rotating and reciprocating engine components
equipment and hand and power tools appropriate to balancing rotating and reciprocating engine components
multi-cylinder engines appropriate to the workplace, including in-line multi-cylinder engine and vee-configuration multi-cylinder engine blocks
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.
