HEAVY MOBILE EQUIPMENT MECHANIC (TITLE 32)

Heavy Mobile Equipment Mechanic

As a Heavy Mobile Equipment Mechanic, WG-5803-10, you will perform repairs, adjust, overhauls, performs major repairs, and maintenance on military and commercial designed heavy mobile equipment and special purpose vehicles. Inspects repairs, overhauls and tests major systems including gasoline, diesel, electric powered hybrid, multi-fuel, turbine, and other types of internal combustion engines, which may be turbo-charged or blower assisted, automatic or manual transmissions, including those with power take offs, cross-drive transmissions, hydraulic, electric, pneumatic systems and controls, fluid pumping systems, turrets, winches and four wheel steering systems. Systematically analyzes malfunctions and the cause of mechanical failure by means of visual and auditory checks, uses computer-controlled test equipment, engine analyzers, compression testers, voltmeters, ohmmeters and pressure gauges in order to determine the exact nature of extent of repairs or adjustments necessary to complete work. Use specialized diagnostic equipment to troubleshoot problems in complex state-of-the-art electric and electronic systems to identify and replace defective components such as computer control modules, sensors, solenoids, digitized components, and circuits. Develop or improvise methods, alter parts, and make repairs in the absence of technical guidelines. Modify parts to fit, or improvises modifications to equipment to correct recurring malfunctions. Makes design modifications to meet special requirements, make adjustment or performs tests. Removes, disassembles overhauls, modifies, adjusts, and repairs, engines, transmissions, or sub-assemblies in accordance with the proper procedures and specifications. Reassembles engines, transmissions, and sub-assemblies, makes adjustments, tests and reinstalls in vehicles and equipment. Determines serviceability by operational driving test. Physical Effort: Heavy mobile equipment mechanics work in tiring or uncomfortable positions for long periods. The work requires frequent standing, bending, reaching, stretching, climbing, and crouching. They work on top of, under, and in tight compartments of vehicles in cramped or awkward positions. They perform strenuous work while standing, lying, or sitting. They frequently lift and carry items, unassisted, weighing up to 40 pounds, and often exert similar effort in pushing, pulling, and positioning parts, assemblies, and equipment. They frequently lift and move heavier items with the assistance of other workers or with lifting devices such as jacks, hoists, and cranes. They are sometimes required to work from ladders or work platforms at varying heights. Working Conditions: Mechanics at this level work both inside and outside. When working inside, they are frequently exposed to drafts, changing temperatures, and noise which are difficult to talk above. When working outside, they may be required to work in bad weather. Workers are often exposed to irritations and discomfort from dust, grease, heat, and fumes. Workers are subject to cuts, burns, chemical irritations, bruises, electrical shock, and injuries for fall from falls while repairing, positioning, and moving equipment. Follows prescribed safety practices. Some safety equipment and clothing may need to be worn for long periods of time.
