This assignment requires a Secret Clearance.  Candidates MUST have an active Secret Clearance

 

Responsibilities

Heavy Mobile Equipment Mechanic:

 

  • Performs the full range of repair, rebuild, overhaul and modification of the largest and more complex heavy mobile equipment, having integrated/interconnected engine systems; for example, armored fighting vehicles (AFVs), locomotive engines, cranes (mobile cranes, portal cranes, locomotive cranes, floating cranes ,and similar), weight and material handling equipment, aerial work platforms, larger construction trucks with diesel engines, large diesel electric generators, and similarly complex heavy mobile equipment used for construction, earth moving, ship loading, and comparable major industrial or special applications. 
  • May provide guidance/oversight over the work of one or more lower-graded mechanics and/or helpers. Has overall responsibility for a variety of systems for the entire vehicle. 
  • Disassembles, inspects, assembles large/complex engines (e.g., up to 16 cylinders and 2000hp). Replaces and fits parts as necessary to close tolerance specifications, (such as, sleeves, pistons, rings, bearings, gears, valves, cams, crankshafts), overhauling components (such as, fuel injection systems, injectors, blowers, turbo-chargers, governors, compressors, hydraulic pumps, etc.). 
  • On cranes, disassembles, repairs and overhauls gear cases, winch works, hydraulic systems, sheaves and hooks, chains, and control systems, and tests and adjusts as necessary. 
  • Repairs, overhauls or rebuilds large, (e.g., 12-cylinder, 1,000 H.P) gasoline or diesel engines requiring a great degree of skill in making difficult and unusually precise repairing, fitting and adjusting of moving parts, engines with pistons which directly power multiple hydraulic and interconnected engine system. The work requires great skill in making difficult, precise fittings and adjustments of moving parts to clearances of one ten-thousandth of an inch or closer, such as in intricate fuel injection systems. 
  • Repairs and overhauls transmissions, gear type, automatic and manual transmissions with braking, steering and differential systems mechanically integrated, such as cross drive or similar multi-system transmissions. 
  • Overhauls a variety of intricate fuel injection systems and diagnoses difficult performance problems and improvises replacement, assembly, repair, and troubleshooting techniques when standard procedures do not suffice. 
  • Manufactures by machining, honing, lapping difficult, precise fittings and adjustments of moving parts, altering parts to fit and mesh in systems for which the parts were not designed. Modifies and fabricates necessary parts to complete the necessary repair, rebuild or overhaul of equipment, vehicles and engines. 
  • Applies extensive knowledge of the principles behind the operation of heavy mobile equipment, along with high skill in the use of diagnostic equipment to determine reasons for mechanical defects or mechanical performance problems in the absence of technical guidelines. 
  • Conducts tests using diagnostic equipment, including computer-controlled test equipment, to identify problems which are difficult to locate and repair. Alters, improvises, or modifies to make items work properly and/or improve performance. 
  • Must operate all equipment and/or vehicles maintained, repaired, overhauled or modified, when work is completed. 

All information for work orders, assets, specifications, and condition assessments is captured in the NAVFAC’s MAXIMO - therefore, candidates must be able to learn and utilize this software platform.

 

Emergency/On-Call: may be required to respond to job related emergencies, within 1 hour of notification.
