Case SR220 Troubleshooting
The
Case SR220 skid steer loader is powered by 207 cu.in (3.4L) FPT F5H FL413
four-cycle four-cylinder turbocharged diesel engine with a rated power of 76 hp
(57 kW) at 2500 rpm. The Case SR220 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 2200 lbs (1000 kg) and tipping load of 4400 lbs
(2000 kg). The boom breakout force is 5490 lbs (2495 kg), and bucket breakout
force is 8700 lbs (3955 kg).
