Case SV185 skid steer loader driveline system components: ISM Shibaura N844LT
4-cycle 4-cylinder turbocharged water-cooled diesel engine with a rated power of
57 hp (42.3 kW), and 1-speed or 2-speed hydrostatic transmission. The hydraulic
system has a pump with a rated capacity of 19.1 gal/min (72 l/min) or 28.7
gal/min (109 l/min). The Case SV185 is equipped with a vertical-lift loader
boom, ASA 80 drive chains, and 10.00x16.5 standard tires. The loader has a boom
breakout force of 3450 lbs (1570 kg) and bucket breakout force of 5550 lbs (2520
kg). The rated operating capacity is 1850 lbs (840 kg), and tipping load is 3700
lbs (1680 kg).
