Elements and Performance Criteria

1. Assess lubrication system operation
   • 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.
   • Lubricant fluid characteristics, terminology and applications are understood.
   • Test equipment is used correctly.
   • Results of spectrographic or laboratory analysis are correctly evaluated and recommendations are made regarding adjustments to future maintenance activities.
   • Auxiliary lubrication systems are assessed for correct operation.
2. Rectify faulty components
   • Replacement components are correctly selected using manufacturers' data.
   • Components are removed and refitted to engine by following prescribed procedures.
   • Final adjustments are made that bring system in line with specifications.
   • Test and rectification activities are accurately recorded.
   • Engine is free of lubricant leaks after repair work is carried out.
   • Component wear and clearances are correctly determined using appropriate test equipment and manufacturers' recommendations.

Required Skills

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 engine lubrication 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 engine lubrication 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.
Faults	Typical symptoms of faults would be lubrication pressures/temperatures that are too low/high; excessive or too little consumption/flow, etc.
Test equipment	Pressure/temperature and/or flow meters
Adjustments	May include setting of bypass/regulating/relief valves to specified pressures of flows
