New Holland L218 Troubleshooting
The
New Holland L218 skid steer loader is powered by Shibaura N844LT 4-cycle
4-cylinder turbocharged liquid-cooled diesel engine with a rated power of 57 hp
(42 kW). The New Holland L218 is equipped with a vertical-lift loader boom,
1-speed or 2-speed hydrostatic transmission, ASA 80 drive chains, and 10x16.5
standard tires. The hydraulic system has a pump with fluid flow rate of 19 gpm
(72 lpm) or 28.8 gpm (109 lpm). The hydraulic pressure is 3045 psi (210 bar).
The skid steer has a rated operating capacity of 1800 lbs (818 kg) and tipping
load of 3600 lbs (1640 kg). The lift height is 120" (3050 mm) to hinge pin, and
dump height is 93.5" (2375 mm).
