Required Skills

Required skills

apply research and interpretive skills sufficient to locate interpret and apply manufacturercomponent supplier procedures workplace policies and procedures

apply analytical skills required for identification and analysis of technical information

apply plain English literacy and communication skills in relation to dealing with customers and team members

apply questioning and active listening skills for example when obtaining information from customers

apply oral communication skills sufficient to convey information and concepts to customers

apply planning and organising skills to work activities including making good use of time and resources sorting out priorities and monitoring own performance

interact effectively with other persons both on a onetoone basis and in groups including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal

apply problemsolving strategies in purposeful ways both in situations where the problem and desired solution are clearly evident and in situations requiring critical thinking and a creative approach to achieve an outcome

use mathematical ideas and techniques to calculate time assess tolerances apply accurate measurements calculate material requirements and establish quality checks

use workplace technology related to overhauling hydrostatic transmissions including the use of electronics computerised technology and communication devices and reporting documenting of results

Required knowledge

A working knowledge of

OHampS regulationsrequirements equipment material and personal safety requirements

identification of the application purpose and operation

identification of component parts to include physical fluid gases and heat generation

identification of wear evaluation methods

types and layout of servicerepair manuals hard copy and electronic

hydrostatic transmission overhaul procedures

hydrostatic transmission system test procedures

manual handling techniques

enterprise quality 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

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

It is essential that competence in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances in the critical aspects of

observing safety procedures and requirements

communicating effectively with others involved in or affected by the work

selecting methods and techniques appropriate to the circumstances

completing preparatory activity in a systematic manner

identification of the application purpose and operation

application of the full overhaul sequence as per the Range Statement relative to the qualification being sought

interpreting the test results

conducting the overhaul in accordance with workplace and manufacturercomponent supplier requirements

completing overhaul of the transmission and associated components within workplace timeframes

presentation of transmission to customerstorage in compliance with work requirements

Context of and specific resources for assessment

Application of competence is to be assessed in the workplace or simulated worksite

Assessment is to occur using standard and authorised work practices safety requirements and environmental constraints

Assessment is to comply with regulatory requirements including Australian Standards

The following resources should be made available

workplace location or simulated workplace

materials relevant to overhauling hydrostatic transmissions

equipment hand and power tooling appropriate to overhauling hydrostatic transmissions

activities covering the mandatory task requirements

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the automotive industrys RSampR Training Package

Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge

Assessment must be by direct observation of tasks with questioning on underpinning knowledge and it must also reinforce the integration of key competencies

Assessment may be applied under project related conditions real or simulated and require evidence of process

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

It is preferable assessment reflects a process rather than an event and occurs over a period of time to cover the varying quality circumstances Evidence of performance may be provided by customers team leadersmembers or other appropriate persons subject to agreed authentication arrangements

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