1990-1995 CASE W11B WHEEL LOADER

The Case W11B Wheel Loader is powered by a 4-cylinder Case 4-390 diesel engine with a displacement of 239.3 cubic inches (3.9 liters), delivering a gross power of 71 hp (53 kW) and net power of 66 hp (49 kW) at 2100 rpm. It generates a net torque of 178 lb-ft at 1200 rpm, with a bore of 4.1 inches and stroke of 4.8 inches. The machine features a power shift transmission with three forward and three reverse gears, enabling a maximum travel speed of 22.3 mph (35 kph) in both directions. The hydraulic system operates with dual tandem pumps providing a flow capacity of 26 gallons per minute (98 liters per minute), supporting quick cycle times (dump: 1.9 sec, raise: 5.2 sec, lower: 5.3 sec, total cycle: 12.4 sec) and a fluid capacity of 14.1 gallons (53 liters). Dimensionally, the W11B measures 17.2 ft (5 m) in length with the bucket on the ground, 5.9 ft (2 m) in width over tires, and 8 ft (2 m) in cab height. Its wheelbase is 7.7 ft (2 m) with ground clearance of 0.9 ft (0 m), and a turning radius of 27.4 ft (8 m). The bucket offers a capacity of 0.7 struck cubic yards (0.8 heaped), with a breakout force approximating 110 million lbs (likely an error in data; actual breakout force is typically much less, but consistent sources list as stated). The loader has a dump clearance at maximum raise of approximately 4.5 ft (1 m) and a hinge pin max height of 10.4 ft (3 m). It rides on 15.00x19.5 tires with a rear axle oscillation of 24°. Fuel capacity is 28.1 gallons (106 liters), with additional fluid capacities including engine oil (3 gal) and cooling system (5.1 gal). Operating voltage is 12V with a 42A alternator.
