Engine Type:
Likely gasoline or diesel options depending on specific configuration of 404/2404. Common IH engines of the era included C-series (e.g., C-123, C-144, C-153) gasoline or BD-series (e.g., BD-144, BD-154) diesel.
Engine Displacement:
Ranges from approximately 123 to 153 cubic inches, depending on engine model (e.g., C-123, C-144, C-153 gasoline; BD-144, BD-154 diesel).
Horsepower Range:
Typically in the 35-50 HP range, depending on engine variant and fuel type.
Torque Specifications:
Specific torque values for engine components (head bolts, main bearings, rod bearings, etc.) are detailed in the manual.
Fuel System Components:
Carburetor (gasoline) or Injection Pump (diesel), Fuel Filters, Fuel Tank, Fuel Lines.
Transmission Type:
Likely a constant mesh, non-synchronized manual transmission with multiple forward gears and one reverse gear. Common IH transmissions for this era include the T-22 or similar variants.
Optional Features:
Possible options could include a Torque Amplifier (TA) unit for on-the-go gear splitting, or specialized PTO configurations.
Gear Ratios:
Specific gear ratios will be detailed within the manual, crucial for performance and task suitability.
Transmission Fluid Capacity:
Specific fluid capacity for the transmission and hydraulic system will be provided, critical for proper operation and lubrication.
Wheelbase:
Varies by specific configuration (e.g., standard, utility, row-crop), but generally compact for its class.
Operating Weight:
Approximately 3,000-4,000 lbs, depending on configuration and equipment.
Engine Weight:
Approximate weight of the engine assembly will be listed for service and removal procedures.
Engine Oil Change Interval:
Typically every 50-100 operating hours or annually, depending on operating conditions. Specific recommendation will be in the manual.

Potential for radiator leaks, thermostat failure, water pump leaks, or radiator hose degradation. Manual provides diagnostic steps.
Brand Heritage:
International Harvester (IH) has a long and storied history in agricultural machinery, known for robust and reliable tractors.
Model Evolution:
The Farmall 404 and 2404 models were part of IH's transition to more modern tractor designs in the late 1950s and early 1960s, offering improved operator comfort and performance over earlier models. The '404' designation often referred to an approximate engine displacement (e.g., 4-cylinder, 04 series).
Model Significance:
These models represented a significant step in IH's offering, bridging the gap between earlier utility tractors and the larger, more powerful machines that followed.
Production Years:
Typically produced from the early 1960s (e.g., 1961-1966 for the 404).
