Overhaul transmissions (manual)

Unit Descriptor This unit covers the competence required to completely dismantle and rebuild manual transmissions. The unit includes identification and confirmation of the work requirement, preparation for work, the testing and analysis of transmissions, the dismantling, assembling, inspection, adjusting, preparation of the manual transmissions for installation and completion of work finalisation processes, including clean-up and documentation.

1 . Prepare to overhaul manual transmission

  1. Nature and scope of the work requirements are identified and confirmed

  2. OH&S requirements, including individual State/Territory regulatory requirements and personal protection needs are observed throughout the work

  3. Procedures and information such as workshop manuals, specifications and tooling, are sourced

  4. Method options are analysed and those most appropriate to the circumstances are selected and prepared

  5. Technical and/or calibration requirements for testing and overhaul are sourced and support equipment is identified and prepared

2 . Test manual transmission and analyse results

  1. Methods for the conduct of the system tests are implemented in accordance with workplace procedures and manufacturer/component supplier specifications

  2. Results are compared with manufacturer/component supplier specifications to indicate compliance or non-compliance

  3. Results are documented with evidence and supporting information and recommendation(s) made

  4. Report is processed in accordance with workplace procedures

3 . Overhaul manual transmission

  1. Information is accessed and interpreted from manufacturer/component supplier specifications

  2. Manual transmissions are overhauled using approved methods and equipment, according to manufacturer/component supplier specifications and tolerances relative to the vehicle/plant manufacturer/component supplier

  3. Manual transmission is overhauled without causing damage to any component or system

  4. Overhauling activities are carried out according to industry regulations/guidelines, OH&S legislation, legislation and enterprise procedures/policies

4 . Prepare transmission for installation

  1. Overhaul schedule documentation is completed

  2. Inspection is made to ensure gears are able to be accessed

  3. Final inspection is made to ensure work is to workplace expectations

  4. Transmission is presented for installation/storage to workplace expectations

  5. Job card is processed in accordance with workplace procedures
