Case SV300 Troubleshooting
The
Case SV300 skid steer loader driveline system components: FPT F5C E5454
4-cylinder turbocharged liquid-cooled diesel engine with a rated power of 84
hp (63 kW), and 1-speed or 2-speed hydrostatic transmission. The hydraulic
system has a pump with a rated capacity of 22.5 gal/min (85 l/min) or 34.6
gal/min (131 l/min). The Case SV300 is equipped with a vertical-lift loader
boom, ASA 100 drive chains, and 12.00x16.5 or 14.00x17.5 tires. The skid steer
loader has a maximum lift height of 130" (3300 mm) to hinge pin and dump height
of 103.5" (2630 mm). The rated operating capacity is 3000 lbs (1365 kg), and
tipping load is 6000 lbs (2730 kg).
