Elements and Performance Criteria

1. Assess induction/exhaust system operation
   • Supercharging, filtering, inter/after cooling principles, terminology and applications are understood.
   • Relevant information is obtained and correctly interpreted prior to any testing.
   • Checks are undertaken safely and to prescribed procedures.
   • Flows, pressures and temperatures are correctly determined and recorded.
   • Faults are correctly isolated to component level and appropriate corrective action is determined.
   • Test instruments and equipment are used correctly.
2. Rectify faulty components
   • Component wear and clearances are correctly determined using manufacturers' recommendations.
   • Replacement components are correctly selected using manufacturers' data.
   • Components are removed and refitted to engine following prescribed procedures.
   • Test and rectification activities are accurately recorded.
   • Engine is free of air/exhaust leaks after repair work is carried out.

Required Skills

Required skills

Look for evidence that confirms skills in reading interpreting and following information on written job instructions specifications standard operating procedures charts lists drawings and other applicable reference documents planning and sequencing operations checking taskrelated information checking for conformance to specification identifying a variety of applications of supercharging filtering inter and after cooling checking the inductionexhaust system for correct operation in accordance with standard operating procedures determining the flows pressures and temperatures of the given inductionexhaust system using appropriate techniques and equipment isolating faulty component in accordance with standard operating procedures using all test instruments and equipment visually and dimensionally checking component parts for wear using supplier catalogues to select component parts removing components and fitting to engines recording all test and where appropriate repair activities checking the inductionexhaust system for leaks undertaking calculations and numerical operations within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of the principles and terminology of supercharging filtering inter and after cooling the performance and operational specifications of the inductionexhaust system the procedures and safety precautions for testing inductionexhaust systems for correct operation the equipment and procedures necessary to test flows pressures and temperatures associated with inductionexhaust systems the procedures for recording flows pressures and temperatures common faults associated with inductionexhaust systems and causes of those faults the appropriate action and procedures for correcting common faults in inductionexhaust systems the component specificationstolerances and actions to be taken if the components are outside of specification the action to be taken if the components are just within specification the measuring instruments to be used to carry out dimensional checks on components the procedures and safety precautions for removingfitting components to engines the procedures for recording test and repair activities undertaken on inductionexhaust systems the consequences of airexhaust leaks on the safe operation of the inductionexhaust system and procedures for testing for leaks in inductionexhaust systems hazards and control measures associate with maintaining and rectifying inductionexhaust systems including housekeeping safe work practices and procedures

Evidence Required

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	A person who demonstrates competency in this unit must be able to maintain and rectify inductionexhaust systems Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with maintaining and rectifying inductionexhaust systems or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Supercharging	Supercharging apparatus includes turbo charging equipment
