New Holland L223 Troubleshooting
The
New Holland L223 skid steer loader is powered by 195.2 cu.in (3.2L) FPT F5C
E5454 four-cylinder turbocharged liquid-cooled diesel engine with a rated power
of 68 hp (51 kW) at 2500 rpm. The New Holland L223 is equipped with a
vertical-lift loader boom, 1-speed or 2-speed hydrostatic transmission, ASA 100
drive chains, and 12x16.5 standard tires. The hydraulic system has a pump with
fluid flow rate of 22.4 gpm (85 lpm) or 34.6 gpm (131 lpm). The skid steer
loader has a rated operating capacity of 2250 lbs (1020 kg) and tipping load of
4500 lbs (2040 kg). The lift height is 130 inches (3290 mm) to hinge pin, and
dump height is 103 inches (2615 mm).
