The technician troubleshoots and repairs electric hydraulic lifting systems, mechanical drive systems, suspensions, and electric and hydraulic control circuits and components.

Core Skills

  • Diesel engine troubleshooting and repair
  • Electric hydraulic lifting system repair
  • Electrical and hydraulic control circuit troubleshooting
  • Mechanical drive and suspension repair

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Mobile Heavy Equipment Mechanics, Except Engines

Repairing crane and man-lift hydraulic systems, mechanical drives, suspensions, and control circuits transfers directly to heavy equipment fault diagnosis and repair.

How to prepare: Practice diagnosis and post-repair performance checks using the service manual for a civilian crane or aerial lift model used by prospective employers.

What the civilian work involves
  • Repair and replace damaged or worn parts.
  • Test mechanical products and equipment after repair or assembly to ensure proper performance and compliance with manufacturers' specifications.
  • Operate and inspect machines or heavy equipment to diagnose defects.
Civilian tools and software (examples)
  • Maintenance management software

Industrial Machinery Mechanics

Troubleshooting lifting-system hydraulics, mechanical drives, and electrical controls provides a foundation for repairing industrial machinery components.

How to prepare: Take a hands-on industrial machinery maintenance course focused on component disassembly, replacement, and reassembly for production equipment.

What the civilian work involves
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Disassemble machinery or equipment to remove parts and make repairs.
  • Reassemble equipment after completion of inspections, testing, or repairs.

Bus and Truck Mechanics and Diesel Engine Specialists

The specialty's verified diesel engine troubleshooting and repair duties provide a direct foundation for civilian diesel diagnostic work.

How to prepare: Complete hands-on training in civilian diesel engine diagnostics, including attaching test instruments and interpreting readings to isolate faults.

What the civilian work involves
  • Attach test instruments to equipment, and read dials and gauges to diagnose malfunctions.
Civilian tools and software (examples)
  • Cummins INSITE
