Case SR270B Troubleshooting
The
Case SR270B skid steer loader is powered by FPT F5B FL413 four-cylinder direct
injection turbocharged diesel engine with a rated power of 84 hp (63 kW) at 2500
rpm. The Case SR270B is equipped with a radial-lift loader boom, single-speed or
two-speed hydrostatic transmission, ASA 100 drive chains, and 12.00x16.5
standard tires. The hydraulic system has a pump with fluid flow rate of 24.2 gpm
(91.5 lpm) or 37.6 gpm (142.5 lpm). The skid steer loader has a rated operating
capacity of 2700 lbs (1225 kg) and tipping load of 5400 lbs (2450 kg). The lift
height is 125.1 inches (3180 mm) to hinge pin, and dump height is 100.9 inches
(2560 mm).
