Case 1845B Troubleshooting
The
Case 1845B skid steer loader is powered by Case 188D four-cylinder naturally
aspirated liquid-cooled diesel engine with a rated power of 49 hp (36.5 kW) at
2200 rpm. The Case 1845B is equipped with a radial-lift loader boom, one-speed
hydrostatic transmission, 80HT drive chains, and 12.00x16.5 or 7.50x16 tires.
The hydraulic system has a pump with fluid flow rate of 16.8 gpm (63.6 lpm). The
hydraulic pressure is 2300 psi (159 bar). The skid steer loader has a rated
operating capacity of 1700 lbs (770 kg) and tipping load of 3120 lbs (1415 kg).
The lift height is 110.5 inches (2805 mm) to hinge pin, and dump height is 84
inches (2135 mm).
