Case 1825B Troubleshooting
The
Case 1825B skid steer loader is powered by 91.4 cu.in (1.5L) Kubota V1505
vertical four-cylinder indirect injection liquid-cooled diesel engine with a
rated power of 27 hp (20.1 kW) at 2400 rpm. The Case 1825B is equipped with a
1-speed hydrostatic transmission, radial-lift loader boom, 60HT drive chain, and
5.70x15 standard tires. The hydraulic system has a pump with fluid flow rate of
9.6 gpm (36.3 lpm). The hydraulic pressure is 2300 psi (159 bar). The skid steer
loader has a rated operating capacity of 885 lbs (400 kg) and tipping load of
1770 lbs (800 kg). The boom breakout force is 1730 lbs (785 kg), and bucket
breakout force is 1795 lbs (815 kg).
