Binding Type Type: Digital Download (PDF) Paper Type Type: N/A (Digital) ⚙️ Engine Specifications Primary Engine Manufacturer: International Harvester (likely a derivative of their BD or DT series diesel engines, or a Continental engine in some markets). Engine Type: Diesel (likely naturally aspirated) Displacement: Approximately 154 cubic inches (2.5 Liters) for the D-179, but variations existed depending on specific configuration. Bore X Stroke: Specifics depend on engine variant, but common for the era's 3-4 cylinder diesels. Performance Horsepower Rated: Around 45-55 PTO horsepower (exact figure varies by configuration and engine). Torque Peak: Not explicitly stated, but designed for strong low-end torque. Fuel System Injection System: Direct injection (typical for IH diesels of this era), likely rotary or inline injection pump. Fuel Type: Diesel Fuel 🔧 Transmission Standard Type: Partial-Power Shift (e.g., IH's own Synchromesh or similar with a torque amplifier option). Gear Configurations: Typically offered multiple forward and reverse gears, often with a synchronized main gearbox and an optional range splitter or torque amplifier. Optional Options: Torque Amplifier (TA) for on-the-go shifting between speed ranges. Features Pto Speeds: Standard PTO speeds (e.g., 540 RPM, and possibly 1000 RPM depending on configuration). 📐 Dimensions Exterior Wheelbase: Approximately 80 inches (2032 mm).
