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.

Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - following work instructions, standard operating procedures (SOPs) and safe work practices; - identifying and interpreting specifications, charts, lists and drawings to perform fault diagnosis, installation and removal of bearings; - performing routine bearing checks during operation and non-operation by observing, listening, feeling and the use of appropriate test equipment; - performing fault diagnosis of bearings using diagnostic techniques and equipment and testing bearings for correct function/malfunction according to manufacturers' specifications; - identifying faulty bearings and causes of failure and taking remedial action to avoid recurrences; - removing bearings from shafts and bearing housings using appropriate fitting techniques and principles, tools, equipment and procedures; and inspecting condition, including measuring bearings and components to specified tolerances and repairing, where appropriate; - installing rotational plain bearings by sizing for correct clearances, lubricating, fitting, tensioning down and running according to specifications and procedures; - installing anti-friction bearings, including ball and roller by determining bearing inside/outside diameters, checking shafts and housings size for correct fit and clearances using appropriate fitting techniques and principles, tools and equipment and seal and cap bearings to specifications, and; - undertaking numerical operations, calculations and formulae for diagnosing, installing and removal of bearings. Students will also be expected to demonstrate the following knowledge: - safe work practices and procedures and use of personal protective equipment (PPE) procedures for checking bearings and seals, checking bearing lubrication/lubrication devices, determining the appropriate clearances for a range of plain bearings and 'sizing' plain bearings; - manufacturer specifications; - engineering principles relating to fault diagnosis, installation and removal of bearings; - reasons for deciding to replace/not replace given bearings; - common causes of bearing failure and their indicators, and; - lubricants and lubrication requirements.
