Elements and Performance Criteria

1. Prepare to diagnose and repair heavy vehicle drive shaft
   • Job requirements are determined from workplace instructions
   • Diagnostic information is sourced and interpreted
   • Diagnostic options are analysed and those most appropriate to the circumstances are selected
   • Hazards associated with the work are identified and risks are managed
   • Diagnostic tools and equipment are selected and checked for serviceability
2. Diagnose drive shaft
   • Diagnostic tests are carried out according to manufacturer specifications, workplace procedures and safety requirements
   • Faults are identified from diagnostic test results and causes of faults are determined
   • Diagnosis findings, including recommendations for necessary repairs or adjustments, are reported according to workplace procedures
3. Repair drive shaft
   • Repair information is sourced and interpreted
   • Repair options are analysed and those most appropriate to the circumstances are selected
   • Repair tools, equipment and materials are selected and checked according to manufacturer procedures
   • Repairs and component replacements and adjustments are carried out according to manufacturer specifications, workplace procedures and safety requirements, and without causing damage to components or systems
   • 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
   • Final inspection is made to ensure work is to workplace expectations and drive shaft or vehicle is presented ready for use
   • Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
   • Tools and equipment are checked and stored according to workplace procedures
   • Workplace documentation is processed according to workplace procedures
