Binding Type Binding Type: N/A (Digital Format) Paper Type Paper Type: N/A (Digital Format) ⚙️ Engine Specifications Primary Engine Primary Engine Variants: Likely features International Harvester's own D-series diesel engines. Specific displacements vary by model within the series, but commonly include variants of the D-154 (2.5L) and D-206 (3.4L) engines, or similar displacements for the larger models. Performance Horsepower Range: Estimated horsepower range from approximately 45 HP for the 454 to over 70 HP for the 674, depending on engine variant and specific model configuration. Fuel System Fuel System Components: Typically equipped with Simms or CAV inline fuel injection pumps and injectors. Manual will cover fuel filter replacement, bleeding the fuel system, injection pump timing, and injector servicing. 🔧 Transmission Standard Standard Transmission: Likely a 7-speed or 8-speed gearbox (e.g., 7 forward + 3 reverse or 8 forward + 4 reverse) with a constant mesh design, coupled with a single or dual-clutch (depending on PTO options). Later models may have featured a synchronized transmission. Optional Optional Transmission Features: Options may have included a torque amplifier (TA) for on-the-go range shifting, providing a total of 14 or 16 speeds. Features Transmission Fluid Specification: Typically specified for a multi-purpose tractor hydraulic fluid (like IH Hy-Tran) or a SAE 80W-90 gear oil for the transmission and differential, depending on the specific sub-model and drivetrain configuration. Manual will detail exact specifications and capacities. 📐 Dimensions Exterior Wheelbase: Varies by model, typically around 80-90 inches for the smaller 454/474 models and extending for the larger 574/674. Weights Operating Weight: Operating weights would range from approximately 3,800 lbs for the 454 to over 5,500 lbs for the 674, before adding ballast. 🛡️ Safety Features Ratings Safety Features Covered: Manual will cover safety aspects related to brake system maintenance, PTO shield operation, ROPS (Roll-Over Protective Structure) requirements (if factory-equipped or an aftermarket addition), and general safe operating practices for tractors of this era. Active Features Active Safety Features: Though active safety features as understood in modern vehicles are absent, the manual covers the proper functioning of mechanical safety systems like parking brake engagement, braking system efficiency checks, and differential lock operation (if equipped). 💡 Technology Features Infotainment Infotainment Systems: N/A - Tractors of this era do not feature infotainment systems. Focus is on functional instrumentation. Driver Assistance Driver Assistance Features: N/A - No electronic driver assistance features present. Control systems are purely mechanical or electro-mechanical (e.g., starter solenoid). Connectivity...
