Case SR160 Troubleshooting
The
Case SR160 skid steer loader is powered by 135.2 cu.in (2.2L) ISM Shibaura
N844LT-F/M4 four-cylinder turbocharged diesel engine with a rated
power of 57 hp (42.3 kW) at 2800 rpm. The Case SR160 is equipped with a
radial-lift loader boom, one-speed hydrostatic transmission, ASA 80 drive
chains, and 10.00x16.5 standard tires. The hydraulic system has a pump with
fluid flow rate of 17.5 gpm (66.2 lpm). The hydraulic pressure is 3050 psi (210
bar). The skid steer loader has a rated operating capacity of 1600 lbs (726 kg)
and tipping load of 3200 lbs (1450 kg). The lift height is 112" (2845 mm)
to hinge pin, and dump height is 88.4" (2245 mm).
