Case 1816C Troubleshooting
The
Case 1816C skid steer loader is powered by 43.3 cubic inches (0.7L) Onan B43M
4-cycle 2-cylinder air-cooled gasoline engine with a rated power of 16 hp (11.9
kW) at 3600 rpm. The Case 1816C is equipped with a single-speed hydrostatic
transmission, radial-lift loader boom, 60H drive chain, and 5.90x15 (Std) or
27x8.50x15 (Opt) tires. The hydraulic system has a pump with fluid flow rate of
8 gpm (30.3 lpm). The hydraulic pressure is 1200 psi (82.8 bar). The skid steer
loader has a rated operating capacity of 500 lbs (227 kg) and tipping load of
1035 lbs (470 kg). The boom breakout force is 1050 lbs (475 kg), and bucket
breakout force is 830 lbs (377 kg).
