Elements and Performance Criteria

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.
Steering and braking systems
Steering and braking systems to be covered in this unit are to include mechanical and hydraulic operated steering clutch/brake, independent drives, planetary and differential planetary, hydrostatic drive, single and multi-disc brake units.
Transmission, steering and breaking failures
Transmission, steering and braking failures covered by this unit are to include those to mechanical, hydraulic and electrical/electronic systems, including control systems, emergency systems, directional stability, calibration/adjustment specifications, contamination, component specifications, component assembly, component damage and system modifications .
Transmission, steering system and braking 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
Tracked mobile plant
Tracked mobile plant covers all mobile plant with tracked undercarriage. Included are tracked type loaders, crawler tractors tracked type plant, hydraulic excavators and face shovels, material handling machines, agricultural tracked equipment and other rural equipments.
Transmission systems
Transmission systems to be covered in this unit are to include mechanical, power shift and automatic transmissions, clutches, torque converters, drivelines and final drive sub-systems.
Coverage
Coverage is to include infinitely variable transmission (belt, hydraulic and planetary).
Unit context
WHS 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.
Evaluative criteria
Evaluative criteria, sometimes referred to as success factors, detail the criteria against which the achievement of the objectives of the analysis are judged. They are to include statistically based criteria and may include other measures.
Isolation procedures
Equipment isolation procedures are to industry and enterprise standards.
Testing equipment
Testing equipment is to include pressure and temperature gauges, flow meters, multimeter, data readers, computer-based diagnostic systems.
Tests
Tests to be conducted are to include system pressures, flow rates, stall testing, operating temperatures, and sensor and actuator integrity.
Personal protective equipment
Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices.
Information and procedures
Workplace procedures relating to the use of tooling and equipment.
Workplace procedures relating to reporting and communication.
Manufacturer/component supplier specifications and application procedures for testing equipment and material.
Manufacturer/component supplier specifications, schematics and operational procedures related to tracked mobile plant steering and braking systems.
Australian Design Rules.
Vehicle industry regulations.
Vehicle industry publications related to emerging steering and braking system technology and technology changes.

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

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 tracked mobile plant transmission, steering and braking systems with real or simulated multi-system 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 repair/modification procedures for tracked mobile plant transmission, steering and braking 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 objective(s) for analysis and evaluation, tracked mobile plant transmission, steering and braking systems with real or simulated faults, monitoring processes and testing equipment appropriate to the objective(s), 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 outcome/product 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 circumstances.
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.
