Unit of competency

Modification History

Release 2. Quantum of hours of workplace practice removed. Supersedes and is equivalent to MEM18005 Perform fault diagnosis, installation and removal of bearings (Release 1).

Release 1. Supersedes and is equivalent to MEM18005B Perform fault diagnosis, installation and removal of bearings.

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.
