1986-1993 KOMATSU WA70-5 WHEEL LOADER

The Komatsu WA70-5 is a compact wheel loader designed for versatile material handling in confined spaces. It features a 60 hp (45 kW) naturally aspirated 4-cylinder engine (model 4D95-LE3) delivering power at 2,350 rpm and a hydrostatic transmission with two forward and two reverse gears, enabling a maximum speed of 12.4 mph (19 kph) in both directions. The machine weighs approximately 11,155 lbs (5,060 kg) and offers a ground clearance of 1 ft (0 m), a wheelbase of 6.7 ft (2 m), and overall length with the bucket on the ground of about 17.6 ft (5 m). Its bucket has a heaped capacity of 1.1 cubic yards (1 m³), a width of 6 ft (2 m), and a breakout force of 8,025 lbs (3,640 kg). The loader’s hydraulic system uses an open circuit with a pump flow capacity of 13.2 gallons/min (49 L/min) and relief valve setting at 3,300 psi, facilitating rapid material handling with a dump time of 0.9 seconds and raise time of 5 seconds. It carries 21.4 gallons (79 L) of fuel, with fluid capacities optimized for engine oil, cooling system, and differential fluids to ensure operational reliability. The machine offers a turning radius of 13.7 ft (4 m) and dump clearance at max raise of 7.7 ft (2 m), making it efficient in tight working environments. The longitudinally mounted engine and well-balanced weight distribution contribute to stable operation and enhanced payload capacity, making the WA70-5 a productive and user-friendly compact wheel loader.
