Unit of Competency MEM27022 - Maintain, fault find and repair traction drive mechanics
Description
Employability Skills
Learning Outcomes and Application This unit of competency defines the skills and knowledge required to maintain and repair traction drive systems on transport and mobile equipment.It covers the skills and knowledge for mechanical related maintenance and fault finding of traction drive systems, including fault finding and rectifying mechanical systems and components supporting the operation of the traction drive system. Where the connection and disconnection of electrical equipment operating above 36 volts is required, see unit MEM18045 Fault find and repair electrical equipment/components up to 250 volts single phase supply or unit MEM18046 Fault find and repair electrical equipment/components up to 1000 volts a.c./1500 volts d.c.The application of the skills and knowledge described in this unit in some states/territories may require an authority to practice in the workplace. Other conditions may apply under state and territory legislative and regulatory requirements.Band: AUnit Weight: 4
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Major traction drive components include the following:

alternator

generator

drive shaft from engine

cooling grid/s

inverters

rectifiers

wheel motors

blowers/fans

Actions to rectify faults include one (1) or more of the following:

on-site repair, including in an on-site workshop

removal of component to a specialist off-site repair facility

referral of the fault to other trade, technical or professional personnel for rectification

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
