Caterpillar 216B3 Troubleshooting
The
Caterpillar 216B3 skid steer loader driveline system components: a 134.1 cu.in
(2.2L) Cat C2.2 four-cylinder direct injection liquid cooled diesel engine with
a rated power of 48 hp (35 kW), and 1-speed hydrostatic transmission. The
hydraulic system has a pump with a rated capacity of 16 gal/min (61 l/min). The
system relief pressure is 3335 psi (230 bar). The Cat 216B3 is equipped with
radial-lift loader boom, 80HS continuous roller chains, and 10x16.5 tires. The
skid steer loader has a boom lifting force of 3168 lbs (1437 kg) and bucket
breakout force of 4083 lbs (1852 kg). The rated operating capacity is 1400 lbs
(635 kg), and tipping load is 2800 lbs (1852 kg).
