Unit of Competency MEM18005 - Perform fault diagnosis, installation and removal of bearings
Description
Employability Skills
Learning Outcomes and Application This unit of competency defines the skills and knowledge required to perform fault diagnosis, installation and removal of bearings.It covers performing routine bearing checks during operation and non-operation, diagnosing bearing faults, identifying bearing requirements for replacement or installation, and removing and installing bearings to industry and enterprise standards of quality and safety.Where diagnostic skills are not required and where straightforward removal and replacement of pre-manufactured bearings is undertaken, unit MEM18055 Dismantle, replace and assemble engineering components should be regarded as sufficient.No licensing, legislative or certification requirements apply to this unit at the time of publication.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.

Plain bearings include one (1) or more of the following:
