The
Case 1816B skid steer loader driveline system components: Tecumseh OH160
four-stroke single-cylinder horizontal shaft air-cooled gasoline engine with a
rated power of 16 hp (11.9 kW), and single-speed hydrostatic transmission. The
hydraulic system has a pump with a rated capacity of 8 gal/min (30.3 l/min). The
system relief pressure is 1200 psi (82.8 bar). The Case 1816B is equipped with a
radial-lift loader boom, 60H drive chain, and 5.90x15 standard tires. The loader
has a boom breakout force of 1050 lbs (475 kg) and bucket breakout force of 830
lbs (377 kg). The rated operating capacity is 500 lbs (227 kg), and tipping load
is 1035 lbs (470 kg).
