2007 - 2017 CASE 821C WHEEL LOADER

Technical Description

The Case 821C Wheel Loader is a robust heavy construction machine engineered for versatility and high performance. It features a turbocharged and air-to-air cooled 6-cylinder engine (model 6TAA-8304) delivering 204 hp gross and 186 hp net power at 2000 rpm, with a torque rise of 51% at 1400 rpm. The machine’s operating weight is approximately 37,901 lbs (17,192 kg), enabling strong stability and operational efficiency. It offers a bucket breakout force of 36,391 lbs (16,507 kg), with a bucket capacity of 3.6 cubic yards heaped, and 3.1 cubic yards struck, supporting significant material movement capacity. The bucket has a width of 9.1 ft (3 m), a dump clearance at max raise of 9.8 ft, and a hinge pin max height of 13 ft, providing excellent reach and dump height. The wheel loader has a wheelbase of 10.5 ft and an overall length with bucket on the ground of 24.6 ft, with a width over tires measuring 8.9 ft, and a top cab height of 11 ft. It runs on 23.5-25 L3 tires and features a turning radius of 18.9 ft for agile maneuverability on site. The transmission includes 4 forward and 3 reverse gears with a proportional 4F/3R electronic control module torque sensing autoshift/manual shift system, supporting speeds up to 23.5 mph forward and 16.6 mph reverse. The hydraulic system includes a dual vane-type tandem pump with 50 gallons per minute flow capacity, 2814 psi relief valve setting, and quick cycle times (dump time 1.6 sec, raise time 5.9 sec). Fluid capacities ensure robust support: 70.8-gallon fuel tank, 46-gallon hydraulic tank, and others for engine oil, transmission, and axles, optimized for sustained heavy-duty operation. The 821C operates on 24V systems with a 65A alternator and features 24° rear axle oscillation for enhanced terrain adaptability. These technical specifications make the Case 821C a reliable and powerful wheel loader suitable for demanding construction and material handling tasks.
