Description
This unit covers performing routine bearing checks during operations and non-operation, diagnosing bearing faults, identifying bearing requirements for replacement or installation, and removing and installing bearings.
Notes
Elements and Performance Criteria
1. Perform routine bearing checks during operation and non-operation
- 1.1. Bearing installation is inspected and task requirements are determined by the most appropriate means.
- 1.2. Bearing installation is checked during operation using standard procedures of listening, feeling, observing and by using test equipment appropriate to the installation.
- 1.3. Seal condition is checked for seal and wear leaks using correct and appropriate means.
- 1.4. Lubricating devices are checked for correct operation using tools and techniques appropriate to the task.
2. Diagnose bearing faults
- 2.1. Visual and sensory inspection of bearing arrangement is performed.
- 2.2. Bearings are tested for correct operation and malfunction using manufacturers' specifications and diagnostic equipment appropriate to the task.
- 2.3. Faulty bearings are identified for replacement using relevant engineering principles.
- 2.4. Causes of failure are identified using techniques and equipment appropriate to the task.
- 2.5. Corrective action to avoid recurrences is taken where necessary.
3. Identify bearing requirements for replacement or installation
- 3.1. Bearing installation is inspected and task requirements are determined.
- 3.2. Operational function of bearings to be installed or replaced is determined using bearing and engineering principles.
4. Remove bearings
- 4.1. Bearing removal techniques and tools are determined for the task.
- 4.2. Bearings are removed from shafts or bearing housings with minimal damage to components.
- 4.3. Condition of serviceable items is inspected using measuring and test equipment appropriate to the task.
- 4.4. Serviceable items are repaired using engineering, techniques, tools and equipment appropriate to the task.
5. Install plain bearings
- 5.1. Standard replaceable items for plain, wrapped, flanged, split bush and thrust bearings are selected from manufacturers' parts lists, catalogues or engineering drawings.
- 5.2. Installation techniques and tools are selected appropriate to the task.
- 5.3. Bearings are sized to correct clearance.
- 5.4. Lubrication requirements are catered for to meet specification and/or application requirements.
- 5.5. Bearings are fitted correctly.
- 5.6. Bearings are tensioned down and run according to standard operating procedures or manufacturers' recommendations.
- 5.7. Final clearance, adjustments and lubrication are checked and corrective action taken if necessary.
6. Install anti-friction bearings
- 6.1. Standard replaceable ball and roller anti-friction bearings are selected from manufacturers' catalogues, spare parts lists or interpreted from engineering drawing to meet specifications.
- 6.2. Bearing inside/outside diameters are determined from specifications or manufacturers' catalogue and checked using measuring instruments appropriate to the task.
- 6.3. Shafts and housings size are checked for correct fit and clearances.
- 6.4. Installation techniques are selected appropriate to the task.
- 6.5. Bearings are fitted to shafts or housings using engineering principles and tools, equipment, techniques appropriate to the task.
- 6.6. Bearing are sealed and, where required, capped, to specifications.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Plain bearings
Rotational plain bearings:
plain bush, wrapped bush, flanged bush, split bush, self-lubricating and thrust bearings for radial, thrust and combination radial and thrust loading applications.
Anti-friction bearings
Ball and roller bearings (anti-friction or rolling element bearings):
self-aligning ball bearings with cylindrical bore, taper bore (and adaptor sleeve), taper bore (and unthreaded adaptor sleeve); single row deep groove ball bearings; magneto bearings (separable ball bearings); single row angular contact ball bearings; double row angular contact ball bearings; spherical roller bearings, including narrow type and C design; spherical roller bearings (NV, N NS Type); double row cylindrical roller bearings; linear ball bearings; needle roller bearings; taper roller bearings; single thrust ball bearings; double thrust ball bearings; single thrust ball bearings with spherical housing washer and seating ring; spherical roller thrust bearings; radial bearings with cylindrical, tapered bore (and adaptor or withdrawal sleeve); and associated bearings for radial, axial and combination radial and axial applications

EVIDENCE GUIDE
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
A person who demonstrates competency in this unit must be able to perform fault diagnosis, installation and removal of bearings. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication materials handling, recording and reporting associated with fault diagnosis, installation and removal of bearings or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
