Description
This unit describes the performance outcomes required to overhaul and return air conditioning and heating, ventilation and air conditioning (HVAC) system compressors to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the compressor, carrying out the overhaul process, reassembling and testing the compressor, and completing workplace processes and documentation.It applies to those working in an automotive service and repair industry. The air conditioning and HVAC system compressors include those fitted to agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery.Licensing requirements apply to this unit. Users are advised to check with relevant regulatory authority.
Notes
Elements and Performance Criteria
1. Prepare to dismantle air conditioning compressor
  • 1.1 Job requirements are determined from workplace instructions
  • 1.2 Australian automotive code of practice: Control of refrigerant gases during manufacture, installation, servicing or de-commissioning of motor vehicle air conditioners is sourced and interpreted
  • 1.3 Dismantling information is sourced and interpreted
  • 1.4 Dismantling options are analysed and those most appropriate to the circumstances are selected
  • 1.5 Hazards associated with the work are identified and risks are managed
  • 1.6 Dismantling tools and equipment are selected and checked for serviceability
2. Dismantle and evaluate compressor and components
  • 2.1 Compressor 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 for serviceability
  • 3.4 Components are machined, repaired and replaced as required, and adjustments are carried out according to manufacturer specifications, workplace procedures, safety and environmental requirements, and Australian automotive code of practice
4. Assemble compressor and components
  • 4.1 Compressor 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 compressor 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 compressor is presented ready for use or storage
  • 5.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
