Federal Motors Trucks For Sale

Axle ratios and tire size drive how a Federal handles modern roads. Many examples were geared for 40 to 50 mph service, typically with a 2-speed rear and non-synchronized main box, so verify road speed targets against your intended use. The Federal Motor Truck Company, often shortened to Federal or Federal Motors, built robust vocational rigs from the teens through the 1950s, including dumps, stake bodies, tractors and fire apparatus. Frames and crossmembers are heavy steel, cabs have simple, serviceable layouts, and sheet metal is straightforward to repair compared with many later designs.

Power is most often gasoline, commonly Hercules, Continental or Waukesha inline-sixes, with some trucks later repowered to Cummins or Detroit Diesel for better torque and fuel economy. Expect 4 or 5-speed manuals paired with Brown-Lipe or auxiliary boxes on heavier models, plus Timken or Eaton 2-speed rears. Braking varies by era, from hydraulic with vacuum assist to full air, always drum. Many trucks left the factory with 6-volt electrical and 20-inch split-ring wheels with tube-type tires; 12-volt conversions and tubeless Budd wheel swaps are common upgrades that improve reliability and serviceability.

For pre-purchase evaluation, start with structure. Inspect frame rails, flanges and riveted crossmembers for corrosion, previous repairs and spring hanger wear. Check cab floors, cowl and windshield surrounds for rust, and confirm the data plate and stamped serials match the title. On-road, assess steering box play, kingpins and shackles, then verify clutch engagement, gear selection and smooth operation of any auxiliary or 2-speed shift. Brake condition is critical on vintage iron, so examine lines, hoses, wheel cylinders or air chambers, and test the hydrovac or compressor output. For dump or fire bodies, cycle PTOs, pumps and hoists, looking for leaks and slow actuation. Tractors should be checked for fifth wheel condition, slider locks and air or electric connections.

Use case drives the build plan. For parades and light-duty hauling, originality and completeness carry value, especially on low-mile fire apparatus and rare bodywork. For regular work, budget for safety upgrades such as dual-circuit brakes, seat belts, LED lighting that respects 6- or 12-volt systems, and modern mirrors. Many states offer antique registration with use limitations, while commercial operation still requires DOT-compliant lighting, reflectors and braking, and CDL rules apply based on GVWR and combination weight. Parts support exists through vintage engine rebuilders, axle specialists and enthusiast networks, but expect longer lead times and some custom fabrication. The right Federal rewards patience with classic looks, stout chassis engineering and a durable, mechanical driving experience.
