Elements and Performance Criteria

1. Assess steering system operation
   • Relevant information is obtained and correctly interpreted prior to any testing.
   • Performance tests are undertaken on primary and/or emergency steering systems safely and to prescribed procedures.
   • Flows, pressures, alignment angles are correctly determined and recorded.
   • Faults are correctly isolated to component level and appropriate corrective action is determined.
   • Power assisted steering component functions, wheel/axle alignment principles, terminology and applications are understood.
   • Test equipment is used correctly.
2. Repair/replace faulty components
   • Component wear and clearances are correctly determined using appropriate test equipment and manufacturers' recommendations.
   • Replacement components are correctly selected using manufacturers' data.
   • Components are removed and refitted following prescribed procedures.
   • Alignment adjustments are made that bring wheel/axles in line with specifications.
   • Test and rectification activities are accurately recorded.
   • Adjustments are made to primary and/or emergency steering systems that bring system in line with specifications.

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 testing steering system for correct performance recording all test results and measurements using all test equipment correctly and appropriately measuring steering system components using appropriate tools techniques and equipment removing and refitting steering system components selecting replacement components using manufacturers data aligning wheels and axles to specification undertaking calculations and numerical operations within the scope of this unit recording test and rectification activities adjusting the steering system in accordance with specifications

Required knowledge

Look for evidence that confirms knowledge of operation of the steering system and its components procedures for testing steering system performance and tests to be undertaken the tools techniques and equipment necessary to maintain and rectify steering systems the reasons for selecting the chosen tools techniques and equipment the precautions to be taken when testing steering systems procedures for recording test results identification of faulty components and corrective action to be taken the reasons for selecting the chosen corrective action the operation of power assisted steering systems the effects of wheelaxle alignment on steering system operation measuring equipment to be used the procedures for checking components for wear and clearance the procedures and precautions for removing and refitting steering system components the procedures for aligning wheels and axles the procedures for recording test and rectification activities the procedures for adjusting primary and emergency steering systems the effect of adjustments on the steering system specifications safe work practices and procedures hazard and control measures associated with maintaining and rectifying steering systems including housekeeping

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 steering 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 steering 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 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.
Steering system	Manual, hydraulically assisted, full hydraulic, articulated and track type systems such as hydrostatic, clutch and differential steering systems for vehicles, mobile plant and equipment
