Elements and Performance Criteria

1. Check and assess items for serviceability
   • Engine consumable fluids and components are correctly assessed for condition.
   • Replacement fluids/items are correctly identified using manufacturers' data.
   • Abnormal appearance/condition of engine consumables fluids and components is identified and reported to appropriate authority.
   • Lubricant, cooling system additives and filtering principles are understood.
2. Perform servicing procedures
   • Engine fluids are drained, flushed and replaced with correct fluid and/or additives, and to the correct level/concentration according to manufacturers' recommendations.
   • Engine consumable components are removed and replaced according to manufacturers' recommended procedures.
   • Engine is free of lubricant, water and air leaks after servicing work.
   • Hoses, wiring, ducts etc. are correctly secured and clear of moving parts after servicing work.
   • Minor running adjustments are made to specification.
   • Test samples of fluids are correctly obtained from system as determined by standard operating procedures.
3. Report activities
   • Servicing activities are accurately recorded on report sheet/proforma, or accurate oral report is given.

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 checking items removed from the engine for serviceability and conformance to specifications planning and sequencing operations checking taskrelated information identifying and reporting on fluids and items which have abnormal appearance flushing engine fluids from the engine and cleaning the engine of any residual fluids replacing engine fluids with the correct fluids to the correct levels removing and replacing engine consumable fluids and components checking the engine for lubricant water and air leaks after servicing securing wires hoses and ducts after servicing making minor running adjustments obtaining test samples undertaking calculations and numerical operations within the scope of this unit recording and reporting service activities

Required knowledge

Look for evidence that confirms knowledge of common defects that can be identified from the appearance of fluids and items the procedures for reporting itemsfluids with abnormal appearance the principles of operation of the lubrication and cooling systems the function of filters the purpose of a range of additives the procedures for draining and flushing fluids from the engine including the reasons for ensuring any residualspilt fluids are removed from the engine the appropriate grade and type of replacement fluid the procedures for replacing engine fluids the correct proportions of additive to be used the procedures for removingreplacing engine consumable fluids and components the procedures for checking serviced engines for leaks the methods of fasteningsecuring wires hoses ducts etc the procedures for undertaking minor running adjustments the specifications pertaining to those adjustments the procedures for taking test samples the procedures for reporting service activities hazards and control measures associated with servicing combustion engines 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 service combustion engines 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 servicing combustion engines 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.
Engine consumable fluids and components	These include components and fluids that are designed to be replaced or restored as their effectiveness diminishes, or where they are wearing/failing. Typically they would include filters, coolants, lubricants, hydraulic and other fluids, additives etc, simple drive belts and coolant hoses
Running adjustments	These are limited to straightforward adjustments typical of which are belt tensions, shroud clearances, linkage adjustments, etc.
