  • Failed module and piece-part replacement

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

Maintaining RAST hydraulic and mechanical subassemblies and replacing failed components transfers directly to industrial machinery component repair.

How to prepare: Take a hands-on industrial machinery maintenance course that includes equipment disassembly and reassembly after component replacement.

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.

Mobile Heavy Equipment Mechanics, Except Engines

RAST hydraulic and mechanical maintenance provides a component-replacement foundation for heavy equipment repair, but the equipment and diagnostic work differ.

How to prepare: Complete hands-on heavy equipment training focused on machine inspection and post-repair performance testing.

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.
