What You'll Learn

Key competencies developed through this program

Auto-populated·from NSX Competency Framework

Mastery: developing (Level 2)(based on Certificate)

  • Hand tools, pneumatic wrenches, and welding equipment — select and operate with limited oversight to complete scheduled repairs on medium-duty diesel trucks.
  • Brake systems, wheel bearings, and steering mechanisms — inspect and evaluate independently against manufacturer specifications during scheduled preventive maintenance visits.
  • Hydraulic hoists and floor jacks — position and operate without direct supervision to safely raise buses and heavy equipment in a busy fleet shop.
  • Brake relining, wheel alignment, and bolt torquing — adjust and complete reassembly to specification across a range of commercial vehicle models encountered in daily workflow.
  • Motor analyzers and chassis diagnostic charts — connect and interpret readings to isolate malfunctions on diesel engines with moderate complexity in a fleet maintenance environment.
  • Preventive maintenance intervals — manage and document oil changes, battery load tests, and lubrication cycles for multiple vehicles using facilities management software.
  • Safety guards and critical fasteners — systematically examine and adjust on returning fleet vehicles, escalating findings that exceed acceptable tolerances to senior staff.
  • Diagnostic data from handheld computers and pressure gauges — analyze and cross-reference to narrow probable causes of reported drivability complaints on route buses.
  • Repair timelines and work orders — prioritize and communicate with dispatchers and service writers to ensure on-time vehicle return in a high-volume commercial shop.
  • Troubleshooting findings and repair recommendations — document clearly using word processing and spreadsheet software to maintain accurate vehicle service histories.
