Description
This unit covers cleaning and assessing parts, recording and interpreting measurements, and reconditioning and setting up the equipment.
Notes
Elements and Performance Criteria
1. Clean and assess parts
- 1.1. Components are disassembled according to manufacturers' recommendations.
- 1.2. Specialised tools are used correctly.
- 1.3. Parts are assessed visually for abnormal wear or defects.
- 1.4. Characteristics of surface finishes and wear patterns associated with pumps/governors/injectors are understood.
- 1.5. Appropriate cleaning method/solution and procedures are selected.
- 1.6. Parts are correctly protected and stored ready for reassembly.
- 1.7. Parts are made identifiable according to their original location in the pump/injector and protected and stored as required for reassembly.
2. Record and interpret measurements
- 2.1. Measurements are accurately obtained and recorded.
- 2.2. Measurements and part condition is correctly interpreted when determining reuse/replacement.
3. Recondition and set up equipment
- 3.1. Fuel system and governing functions, characteristics, applications and terminology are understood.
- 3.2. Components identified as faulty are reconditioned and replaced.
- 3.3. Components are assembled according to manufacturers' specifications.
- 3.4. Test equipment is used correctly.
- 3.5. Components are tested and set to specifications.
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.
Governors
Governor types include mechanical, pneumatic, hydraulic and electronic

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
A person who demonstrates competency in this unit must be able to overhaul engine fuel system components. 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 overhauling engine fuel system components, 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, supervisor's 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.
