Description
This unit describes the performance outcomes required to return a hydrostatic transmission to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the transmission, carrying out the overhaul procedures, reassembling and testing the transmission, and completing workplace processes and documentation.It applies to those working on hydrostatic transmissions in vehicles from all sectors of the industry.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare to dismantle hydrostatic transmission
  • 1.1 Job requirements are determined from workplace instructions
  • 1.2 Dismantling information is sourced and interpreted
  • 1.3 Dismantling 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 Dismantling tools and equipment are selected and checked for serviceability
2. Dismantle and evaluate hydrostatic transmission and components
  • 2.1 Transmission is dismantled in a logical sequence according to manufacturer and workplace procedures, and safety and environmental requirements, and without causing unnecessary damage to components or systems
  • 2.2 Components are cleaned for evaluation according to workplace procedures and safety and environmental requirements
  • 2.3 Components are measured and compared with manufacturer specifications and serviceability is determined
  • 2.4 Component repair method is determined
  • 2.5 Unserviceable parts are identified and replacement parts sourced
3. Carry out overhaul
  • 3.1 Overhaul information is sourced and interpreted
  • 3.2 Overhaul options are analysed and those most appropriate to the circumstances are selected
  • 3.3 Overhaul tools and equipment are selected and checked according for serviceability
  • 3.4 Components are machined, repaired and replaced as required, and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems
4. Assemble transmission and components
  • 4.1 Transmission is assembled according to manufacturer specifications, workplace procedures, and safety and environmental requirements
  • 4.2 Tolerances and clearances are measured against manufacturer specifications and necessary adjustments are made
  • 4.3 Assembly of transmission is completed within workplace timeframes and without causing damage to other components or systems
  • 4.4 Post-assembly testing is carried out according to workplace procedures and safety and environmental requirements, and any problems detected as having been introduced during the assembly process are rectified
5. Complete work processes
  • 5.1 Final inspection is made to ensure work is to workplace expectations and transmission is presented ready for use or storage
