Case SV340B Troubleshooting
The
Case SV340B skid steer loader driveline system components: FPT F5B FL413D
4-cylinder direct injection turbocharged diesel engine with a rated power of
91.2 hp (68 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 38.7
gal/min (146.5 l/min). The Case SV340B is equipped with a vertical-lift loader
boom, ASA 100 drive chains, and 14.00x17.5 standard tires. The skid steer loader
has a rated operating capacity of 3400 lbs (1545 kg) and tipping load of 6800
lbs (3090 kg). The boom breakout force is 6815 lbs (3100 kg), and bucket
breakout force is 9530 lbs (4330 kg).
