Specific engine variants will differ across the 770 through 1175 models. The manual should detail these specific engine designations. Engine Block Material: Typically cast iron construction for the engine block and cylinder heads, characteristic of diesel engines of this period. Performance Typical Power Output: Power outputs range from approximately 50 HP for the 770 to over 100 HP for the 1175/1170 models. Exact HP and torque figures will be model and engine specific within the manual. Fuel System Fuel Injection Type: Typically rotary or inline injection pumps (e.g., Simms, CAV, or Lucas-CAV). Turbocharged variants will have specific intercooler and fuel system adjustments. Manual covers testing and calibration. 🔧 Transmission Standard Gearbox Type: Primarily manual transmissions with multiple gear ratios (e.g., 8-speed, 12-speed). Some larger models may have offered synchronized gearboxes or auxiliary gearboxes. Optional Power Shift: The manual explicitly mentions 'Power shift clutch', indicating coverage of models or options equipped with powershift transmissions, likely a torque converter-based system or a specific integrated powershift unit. Features Pto And Hitching: Details on PTO operation (540/1000 RPM), clutch engagement, and hydraulic hitch control systems are covered. Gear Reduction Systems: Detailed explanation of the gear reduction systems within the transmission and final drives, including lubrication and wear checks. 📐 Dimensions Exterior Wheelbase And Length: Dimensions vary significantly across the model range. The manual will provide exact wheelbase, length, width, and height specifications for each model. For example, the 770/870 would be smaller than the 1170/1175. Weights Operating Weight: Operating weights will range from approximately 4,000 lbs for the 770 to over 8,000 lbs for the 1175. The manual will list exact unladen and...
