While not explicitly stated, these typically include powerful diesel engines designed for heavy-duty line haul operations (e.g., Cummins ISX series or Detroit Diesel DD15, depending on specific configurations). Performance Horsepower Range: Expected range for heavy-duty line haul: 400-600+ HP (specifics would be within the manual). Torque Range: Expected range for heavy-duty line haul: 1200-2000+ lb-ft (specifics would be within the manual). Fuel System Type: Common Rail Diesel Injection (CRDI) or similar advanced diesel fuel systems. Components: Includes information on fuel pumps, injectors, filters, and high-pressure lines. Transmission Standard Type: Typically a heavy-duty manual or automated manual transmission (AMT) from manufacturers like Eaton Fuller. Optional Type: Possible availability of automatic transmissions depending on specific military or civilian configurations. Features Coverage: Detailed procedures for clutch operation, gear shifting mechanisms, and transmission maintenance. Dimensions Exterior Wheelbase: Variable, but typically long for line haul stability (specifics in manual). Weights Gvwr: High Gross Vehicle Weight Rating, typically exceeding 50,000 lbs (specifics in manual). Gcwr: High Gross Combined Weight Rating, designed for heavy trailer loads (specifics in manual). Safety Features Ratings Description: As a heavy-duty military truck, safety would be paramount, with emphasis on robust construction and reliable braking systems.
