Case 1737 Troubleshooting
The
Case 1737 skid steer loader is powered by 148 cu.in (2.4L) Case G148B 4-cycle
4-cylinder overhead valve gasoline engine with a rated power of 37 hp (27.5 kW)
at 2000 rpm. The Case 1737 is equipped with a radial-lift loader boom, variable
speed sheave transmission, 80H drive chains, and 7.00x15 or 10.00x16.5 tires.
The hydraulic system has a pump with fluid flow rate of 18 gpm (68.2 lpm). The
hydraulic pressure is 2600 psi (180 bar). The skid steer loader has a rated
operating capacity of 1700 lbs (770 kg) and tipping load of 2080 lbs (945 kg).
The lift height is 115.5 inches (2935 mm) to hinge pin, and dump height is 86.5
inches (2195 mm).
