  • Hydraulic pump and flow divider repair
  • Hydraulic fluid purifier maintenance
  • Diesel engine and aircraft jack 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.

Industrial Machinery Mechanics

Repairing hydraulic test stands, pumps, power supplies, and electrical control circuits transfers directly to maintaining industrial machinery and its components.

How to prepare: Build a repair portfolio showing how you diagnosed and corrected hydraulic or electrical control faults, then target industrial maintenance openings involving hydraulic equipment.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Disassemble machinery or equipment to remove parts and make repairs.

Mobile Heavy Equipment Mechanics, Except Engines

Experience troubleshooting hydraulic circuits and repairing pumps, flow dividers, and power supplies provides a foundation for heavy-equipment component repair.

How to prepare: Practice diagnosing a target manufacturer's heavy-equipment hydraulic system using its operating manual and technical drawings.

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.
  • Read and understand operating manuals, blueprints, and technical drawings.
Civilian tools and software (examples)
  • Maintenance management software

Bus and Truck Mechanics and Diesel Engine Specialists

Verified diesel-engine repair and hydraulic and electrical circuit troubleshooting provide a foundation for commercial diesel diagnostic work.

How to prepare: Take hands-on commercial diesel diagnostic training that includes attaching test instruments and interpreting engine diagnostic software.

What the civilian work involves
  • Attach test instruments to equipment, and read dials and gauges to diagnose malfunctions.
  • Use handtools, such as screwdrivers, pliers, wrenches, pressure gauges, or precision instruments, as well as power tools, such as pneumatic wrenches, lathes, welding equipment, or jacks and hoists.
Civilian tools and software (examples)
  • Cummins INSITE
