Engine Options 2007:
Primarily featured Caterpillar C7 and Cummins ISB diesel engines. Specific displacements and configurations varied greatly based on customer order and GVWR class.
Horsepower Range:
Typically ranging from 200 hp to over 300 hp, depending on engine variant and application.
Torque Range:
Significant torque output, crucial for heavy-duty work, often exceeding 600 lb-ft.
Injection System:
Commonly high-pressure common rail (HPCR) direct injection systems for Caterpillar and Cummins engines.
Transmission Type Standard:
Manual transmissions were common, often with 5, 6, or more speeds. Allison automatic transmissions were a popular option.
Transmission Type Optional:
Various heavy-duty automatic transmissions, such as Allison models (e.g., 2000, 3000 Series), were frequently specified.
Gear Ratios:
Manual transmissions offered a range of gear ratios optimized for heavy loads and various duty cycles. Automatic transmissions featured multi-speed ranges for efficient power delivery.
Gvwr Range:
Gross Vehicle Weight Rating (GVWR) typically started around 25,500 lbs and could extend significantly higher, into Class 7 and even some Class 8 configurations depending on specific build.
Cab Configurations:
Available in regular cab and crew cab configurations, offering varying passenger and cargo space.
Body Styles:
Offered as a bare chassis for custom bodybuilding, allowing for a wide array of vocational upfits such as dump bodies, service bodies, van bodies, flatbeds, and tow truck equipment.
Curb Weight:
Varies significantly based on engine, transmission, cab configuration, and upfit, but generally starts in the 10,000-15,000 lb range for a basic chassis.
Crash Test Data:
Commercial vehicles of this class are typically subject to different testing standards than light-duty vehicles. Focus is on structural integrity and occupant protection during typical duty cycles. Specific NHTSA or IIHS ratings might not be directly comparable to passenger cars.
Braking Systems:
Hydraulic disc brakes on all wheels are standard, often with ABS. Air brakes may be an option on heavier configurations.
Occupant Protection:
Includes safety belts, reinforced cab structures, and potentially airbag systems depending on specific options and regulations for the year.
Oil Change Interval:
Typically every 5,000-10,000 miles or 250-500 operating hours for diesel engines, depending on operating conditions and oil type. Refer to specific engine manufacturer recommendations.
Fuel Filter Replacement:
Recommended at intervals specified by the engine manufacturer, often tied to mileage or hours of operation, and crucial for diesel engine health.
Engine Oil Type:
API CJ-4 or newer specification heavy-duty diesel engine oil. Viscosity grades like 15W-40 or 5W-40 are common, depending on climate and engine model. Consult engine manufacturer specs.
Coolant Type:
Heavy-duty organic acid technology (OAT) or hybrid organic acid technology (HOAT) coolant, typically a red or orange extended-life coolant. Specifics depend on the engine manufacturer (Caterpillar or Cummins).
Transmission Fluid Type:
For manual transmissions, SAE 75W-90 or 75W-140 gear oil. For Allison automatics, specific Allison TES-295 approved fluid is required. Always check the vehicle's specific transmission type.
Common Wear Items:
Brake components (pads, rotors, drums), suspension bushings, tie rod ends, and exhaust system components are common wear items due to the heavy-duty nature of the vehicle.
Engine Specific Concerns:
Depending on the specific engine option (Caterpillar C7 or Cummins ISB), potential issues could include EGR system problems, turbocharger wear, or fuel injector issues, as with many modern diesel engines of that era.
Ford Trucks Division:
Ford has a long-standing reputation in the commercial vehicle market, with the F-Series line dating back to the mid-20th century. The F-650 is part of their robust lineup of medium-duty trucks.
F650 Legacy:
The F-650 has evolved from earlier Ford medium-duty offerings, becoming a cornerstone for vocational applications, known for its durability and adaptability.
Manufacturing Plant:
Ford's F-650 and F-750 trucks are typically manufactured in their dedicated North American commercial vehicle assembly plants, such as the Louisville Assembly Plant in Kentucky (historically).
