Case 221F Troubleshooting

The Case 221F compact wheel loader is powered by FPT F5H FL463 4-cycle 4-cylinder direct injection turbocharged liquid-cooled diesel engine with a rated power of 70 hp (52 kW) at 2500 rpm. The Case 221F is equipped with a hydrostatic transmission, power steering system, hydraulic wet disc brakes, and 365/80R20 standard tires. The open center hydraulic system has a gear pump with fluid flow rate of 22.5 gpm (85 lpm). The compact wheel loader has a rated operating capacity of 4010 lbs (1820 kg) and tipping load of 8020 lbs (3640 kg). The maximum lift height is 129.5" (3290 mm) to hinge pin, and bucket breakout force is 10960 lbs (4970 kg).

Engine Troubleshooting
