Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Interpret work order and locate and apply information

Apply safety requirements including the isolation of equipment and use of personal protective equipment

Follow work instructions operating procedures and inspection processes to

minimise the risk of injury to self and others

prevent damage and wastage of goods equipment and products

maintain required production output and product quality

Complete failure analyses on a minimum of three wheeled mobile plant transmission systems with real or simulated multisystem and intermittent faults and identify evaluate select and document the most appropriate rectification measure

Analyse and validate or recommend variations to a minimum of two available repairmodification procedures for wheeled mobile plant transmission systems

Document and report the diagnostic process and findings and recommended rectification for two of the above

Work effectively with others

Modify activities to cater for variations in workplace context and environment

Context of and specific resources for assessment

Assessment may occur on the job or in a workplace simulated facility with process equipment material work instructions and deadlines

Access to a requirement and objectives for analysis and evaluation wheeled mobile plant transmission systems with real or simulated faults monitoring processes and testing equipment appropriate to the objectives research facilities and technical information and a work environment

Method of assessment

Assessment of this unit of competence is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process Direct evidence may include certification of compliance of the final outcomeproduct or authorisation for use by a competent authority

Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances but is able to be transferred to other circumstance

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role

Guidance information for assessment


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.

Failure analysis and evaluation process

The objective of the failure analysis and evaluation process may be to determine fault rectification measures, to effect variation in system characteristics and parameters or to enhance system performance.

Wheeled mobile plant

Wheeled mobile plant covers all mobile plant other than that with tracked undercarriage. Included are loaders, dump trucks, graders, scrapers, industrial tractors, materials handling machines, agricultural harvesters and other rural equipment.

Systems

Transmission systems to be covered in this unit are to include mechanical, power shift and automatic transmissions with integrated computer controls and clutches, torque converters, drivelines, differentials and final drive sub-systems.

System faults

Transmission system faults covered by this unit are to include abnormal component wear, clutch operations, clutch pack slippage, contamination, driveline phasing and alignment, hard shifting, leaks, loose mountings, lubrication, modulation, noises, operating temperature, system pressures, torque converter slippage and vibrations.

System failures

Transmission system failures covered by this unit are to include indirect faults caused by the influence of external systems which may or may not be faulty in their primary operations.

Unit context

OH&S requirements include vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures.

Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements.

Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults.
