Inspect and service marine inboard transmissions


Application

This unit describes the performance outcomes required to inspect and service marine inboard transmissions. It involves preparing for the task, inspecting the transmission, reporting the inspection findings, servicing and adjusting the transmission, and completing workplace processes and documentation.

It applies to those working in the marine 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 inspect and service inboard transmission

1.1 Job requirements are determined from workplace instructions

1.2 Servicing information is sourced and interpreted

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

1.4 Tools, equipment and materials are selected and checked for serviceability

2. Inspect transmission

2.1 Inspection is carried out according to manufacturer specifications, workplace procedures and safety requirements

2.2 Inspection results are compared with manufacturer specifications

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

3. Service transmission

3.1 Service and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems

3.2 Post-service testing is carried out according to workplace procedures

4. Complete work processes

4.1 Final inspection is made to ensure work is to workplace expectations and transmission 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

4.4 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:

inspect and service two different marine transmissions, including:

one inline transmission

one ‘V’ drive transmission.


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 inspecting and servicing marine inboard transmissions, including procedures for identifying hazards and controlling risks associated with working with rotating shafts and pulleys

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

identification and function of marine inboard transmissions, including:

'V' drive transmissions

inline transmissions

step-up transmissions

hydraulic transmissions

mechanical transmissions

counter shaft transmissions

planetary gear transmissions

mechanical dog clutches

basic operation of marine inboard transmissions, including:

mechanical transmissions

hydraulic transmissions

types and applications of lubricants and lubricating fluids for inboard transmissions

inspection procedures for marine inboard transmissions, including oil and fluid condition and leaks

service and adjustment procedures for marine inboard transmissions, including:

replenishing lubricants

control system with forward, neutral and reverse

cooling system

post-service testing procedures for marine inboard 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 marine inboard 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:

marine repair workplace or simulated workplace

workplace instructions

manufacturer inboard transmission specifications

two different vessels with the inboard transmissions specified in the performance evidence and requiring servicing

tools, equipment and materials appropriate for inspecting and servicing marine inboard transmissions.
