Binding Type Binding Type: N/A (PDF Format) Paper Type Paper Type: N/A (PDF Format) ⚙️ Engine Specifications Primary Engine Engine Family: Likely an International Harvester's own diesel engine line, possibly a variant of the BD or DT series, or sourced from a supplier like Waukesha or Perkins, depending on the exact build configuration. Displacement: Specific displacement varies, but common IH diesel engines in this class ranged from approximately 4.0L to 6.0L (240-360 cubic inches). Performance Horsepower Range: Estimated to be in the 50-75 PTO horsepower range, depending on the specific engine option and configuration. Torque Characteristics: Designed for strong low-end torque essential for pulling heavy loads and operating at lower RPMs. Fuel System Fuel Type: Diesel Injection Type: Likely direct injection with a rotary or inline injection pump (e.g., Stanadyne, Bosch). Cooling System Cooling Method: Water-cooled Lubrication System Oil Capacity: Typically around 10-12 US quarts (9.5-11.4 liters), including filter. Specific capacity to be confirmed in manual. Governor Governor Type: Mechanical centrifugal governor 🔧 Transmission Standard Gearbox Type: Likely a manual gearbox with multiple forward and reverse speeds (e.g., 8-speed, 16-speed Synchro-Range or constant mesh). Optional Transmission Options: Potential for creeper gears or specialized transmission configurations depending on the market and application. Features Pto: Standard Power Take-Off (PTO) with multiple speeds (e.g., 540 RPM, 1000 RPM) or ground speed PTO. Clutch Type: Dual-stage clutch (independent PTO clutch and main transmission clutch) is common for this era. Fluid Capacity Transmission Oil Capacity: Approximately 18-25 US quarts (17-23.7 liters) for the main transmission and differential. Specific type and capacity crucial. Fluid Type Transmission Fluid Recommendation: Typically a multi-purpose tractor fluid (e.g., Universal Tractor Transmission Oil - UTTO) or specific IH Hy-Trans fluid. Manual will specify. 📐 Dimensions Exterior Wheelbase: Estimated 85-95 inches (2159-2413 mm), depending on configuration. Weights Operating Weight: Estimated 5,000 - 7,000 lbs (2268 - 3175 kg), without ballast. Drawbar Horsepower: Typically around 85-90% of PTO horsepower, signifying effective pulling power. 🛡️ Safety Features Ratings Rollover Protection: ROPS (Roll-Over Protective Structure) was often an...
