The
Case SR240 skid steer loader driveline system components: FPT F5H FL463A
4-cylinder direct injection turbocharged diesel engine with a rated power of 68
hp (51 kW), and 1-speed or 2-speed hydrostatic transmission. The hydraulic
system has a pump with a rated capacity of 24.2 gal/min (91.5 l/min) or 37.6
gal/min (142.5 l/min). The Case SR240 is equipped with a radial-lift loader
boom, ASA 100 drive chains, and 12.00x16.5 standard tires. The skid steer loader
has a rated operating capacity of 2400 lbs (1090 kg) and tipping load of 4800
lbs (2180 kg). The boom breakout force is 5530 lbs (2510 kg), and bucket
breakout force is 8680 lbs (3945 kg).
