Common options included the D-239 and D-310 engines. Specific engine displacement, bore, stroke, and compression ratios would be detailed within the manual. Performance Horsepower And Torque: Specific horsepower and torque figures for various engine configurations (e.g., D-239, D-310) and potential de-rated versions for different applications would be found in the manual's specifications section. Fuel System Fuel Type: Diesel Injection System: Likely mechanical direct injection, potentially with rotary or inline injection pumps from manufacturers like CAV, Stanadyne, or Bosch, depending on the specific engine and build date. Manual would detail pump timing and calibration. Cooling System Cooling Type: Water-cooled Lubrication System Oil Type And Capacity: The manual would specify the exact API service classification (e.g., CD or CE for diesel engines of that era) and viscosity grade (e.g., SAE 15W-40 or 30) for engine oil, along with the total oil capacity including filter. 🔧 Transmission Standard Gearbox Options: The 766 offered a range of transmissions. A primary option was the 'Power Transfer' (PT) 5-speed synchronized transmission. An optional 'Load-Star' or 'Torque Amplifier' (TA) transmission, providing 16 forward and 8 reverse speeds with clutchless shifting between ranges, was also a significant feature. The manual would cover both. Optional Transmission Types: While a manual transmission was standard, the 'Torque Amplifier' (TA) was a highly sought-after option, significantly enhancing operational versatility and reducing operator fatigue. Features Transmission Features: Synchronized shifting, optional Torque Amplifier for on-the-go range changes, heavy-duty final drives. Fluid Specifications Transmission Fluid Type: The manual would specify the appropriate lubricant for the manual transmission and the hydraulic/transaxle fluid for the Power Transfer or Torque Amplifier systems, likely an IH Hy-Tran fluid or equivalent. Capacities for each would be listed. 📐 Dimensions Exterior Overall Length: Approximately 135 inches (3429 mm) without front weights or mounted implements. Specific dimensions vary slightly by configuration. Overall Width: Approximately 72 inches (1829 mm) at the rear wheels, adjustable. Specific width depends on tire and wheel configuration. Wheelbase: Approximately 84 inches (2134 mm). Weights Operating Weight: Around 5,500 - 6,500 lbs (2495 - 2948 kg) depending on configuration and options. The manual would provide exact weights for various configurations. Drawbar Horsepower: The 766 was rated for approximately 55-60 PTO horsepower, which translates to a specific range of drawbar horsepower, a key metric for tractor performance. 💡 Technology Features Infotainment Operator Interface: Basic analog gauges for engine temperature, oil pressure, fuel level, and tachometer. Functionality focused on operational status and driver input (lever controls). Driver Assistance Control Systems: Mechanical linkage for steering, clutch, and transmission engagement. The optional Torque Amplifier provided a form of 'assist' for gear changes. Hydrau-Lift or similar 3-point hitch system for implement control. Connectivity Power...
