Diagnose and repair motorcycle manual transmissions


Application

This unit describes the performance outcomes required to diagnose and repair faults in the manual transmissions of motorcycles. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

Elements

Elements describe the essential outcomes.

Performance Criteria

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Prepare to diagnose and repair motorcycle manual transmission

1.1 Job requirements are determined from workplace instructions

1.2 Diagnostic information is sourced and interpreted

1.3 Diagnostic options are analysed and those most appropriate to the circumstances are selected

1.4 Hazards associated with the work are identified and risks are managed

1.5 Diagnostic tools and equipment are selected and checked for serviceability

2. Diagnose manual transmission

2.1 Diagnostic tests are performed according to workplace procedures and safety and environmental requirements

2.2 Faults are identified from diagnostic test results and causes of faults are determined

2.3 Diagnosis findings are reported according to workplace procedures, including recommendations for necessary repairs or adjustments

3. Repair manual transmission

3.1 Repair information is sourced and interpreted

3.2 Repair options are analysed and those most appropriate to the circumstances are selected

3.3 Repair tools, equipment and materials are selected and checked

3.4 Repairs and component replacements and adjustments are carried out according to manufacturer specifications, safety and environmental requirements, and without causing damage to components or system

3.5 Post-repair testing is carried out according to workplace procedures to confirm fault rectification, and any further problems detected as having been introduced during the repair process are rectified

4. Complete work processes

4.1 Final inspection is made to ensure work is to workplace expectations and motorcycle is presented ready for use

4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected

4.3 Tools and equipment are checked and stored according to workplace procedures

4.5 Workplace documentation is processed according to workplace procedures

Evidence of Performance

Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

diagnose and repair a fault in two different motorcycles with different manual transmissions, in which the work must involve removing, dismantling, reassembling and refitting the transmissions.


Evidence of Knowledge

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing motorcycle manual transmissions, including procedures for handling transmission fluids and clutch materials

environmental requirements, including procedures for trapping, storing and disposing of fluids released from transmissions

operating principles of motorcycle manual transmissions and associated components, including:

gears types

gear ratios

application, purpose and operation of motorcycle manual transmissions and components, including:

transmission types, including:

vertical split-type crankcase

horizontal split-type crankcase

cassette-type

sliding gear transmissions, including:

dog clutches

shifter drums

cam plates

constant-mesh transmissions, including ball lock-type systems

quick shifters

types and compatibility of transmission system oils and additives

diagnostic testing procedures for motorcycle manual transmissions, including procedures for analysing:

component wear

abnormal system noise

repair procedures for motorcycle manual transmissions, including procedures for removing, dismantling, reassembling, refitting and adjusting components

post-repair testing procedures for motorcycle manual transmissions.


Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the motorcycle manual transmissions that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

motorcycle repair workplace or simulated workplace

workplace instructions

manufacturer motorcycle manual transmission specifications

two different motorcycles with different manual transmissions with faults

diagnostic equipment for motorcycle manual transmissions

tools, equipment and materials appropriate for repairing motorcycle manual transmissions.


Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills

Description

Learning skills to:

locate appropriate sources of information efficiently.

Reading skills to:

interpret information from manufacturer and workshop literature when seeking manual transmission specifications and procedures.

Writing skills to:

legibly and accurately fill out workplace documentation when reporting diagnosis findings, making repair recommendations, and recording parts and material used.

Oral communication skills to:

clarify instructions

report diagnostic findings and make repair recommendations.

Numeracy skills to:

measure manual transmission components and use basic mathematical operations, including addition and subtraction, to calculate distances, tolerances and deviations from manufacturer specifications.

Planning and organising skills to:

plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.

Technology skills to:

use measuring equipment, such as tape measures, rulers and vernier calipers.
