Requirements Software Requirement: Adobe PDF Reader ⚙️ Engine Specifications Primary Engine Engine Type: Likely one of the robust Land Rover petrol (e.g., 2.25L, 2.5L) or diesel engines of the era. Specific engine variant depends on original configuration. Performance Horsepower: Typically in the range of 60-85 HP for petrol variants, and 50-70 HP for diesel variants (specifics vary by engine code). Torque: Torque figures would be documented for optimal power delivery off-road and under load. Specific figures vary by engine. Fuel System Fuel Delivery: Typically carbureted (e.g., Zenith, SU) for petrol engines; direct injection for diesel engines. Fuel Type: Unleaded gasoline or Diesel fuel, depending on engine variant. 🔧 Transmission Standard Type: Four-speed or five-speed manual transmission (synchromesh on higher gears). Transfer Case: Two-speed transfer case with selectable four-wheel drive (4WD) and often a centre differential lock. Optional Type: Some later Series 3 models may have offered an automatic transmission option, though less common for the 109. Features Gear Ratios: Specific gear ratios for both the main gearbox and the transfer case, crucial for off-road performance and towing. Fluid Type: Manual transmission fluid (MTF) specification (e.g., GL-4, GL-5) and transfer case oil type. 📐 Dimensions Exterior Wheelbase: 109 inches (approx. 2768 mm) Body Styles: Station Wagon, Hardtop, Pickup Truck, Chassis Cab.
