Engine Displacement Diesel:
Typically around 250-270 cubic inches (e.g., 4.3-4.4 Liters for the 4.25-inch bore diesel).
Horsepower Diesel:
Rated PTO horsepower often in the range of 50-60 HP, with drawbar horsepower slightly lower.
Torque Diesel:
Torque figures varied with engine tune, but generally provided strong pulling power for its class.
Fuel System Diesel:
Roosamaster, CAV, or similar inline injection pumps with individual injectors. Carbureted gasoline engines also existed.
Fuel Type:
Diesel fuel (for diesel variants), Gasoline (for gasoline variants).
Oil Type Recommendation:
API CD or CE rated diesel engine oil, viscosity grade like 15W-40 or 10W-30 depending on operating temperature. Consult manual for specific viscosity.
Coolant Type:
Ethylene glycol based antifreeze mixed with distilled water (50/50 ratio typically). Check manual for specific additive requirements.
Transmission Type:
Constant mesh, spur-gear type transmission with multiple forward and reverse gears. Common configurations included 6-speed forward and 2-speed reverse.
Optional Features:
Possible option of a 'Shuttle-Shift' or range transmission for easier directional changes.
Transmission Fluid:
Typically used API GL-4 or GL-5 gear oil (e.g., 80W-90) for the transmission and differential. Check manual for exact specification and capacity.
Clutch Type:
Dry single-plate or dual-plate clutch, depending on specific D-19 model variant.
Overall Length:
Variable based on configuration, but typically in the range of 125-140 inches (317-355 cm).
Wheelbase:
Standard wheelbase around 80-84 inches (203-213 cm).
Operating Weight:
Typically in the range of 5,000-6,000 lbs (2268-2722 kg) without ballast.
