Case 310B Backhoe Loader

The Case 310B is a two-wheel drive backhoe loader. This model was manufactured between 1958 and 1960. The Case 310B is powered by Case G148 four-stroke 4-cylinder liquid-cooled gasoline engine with a maximum power of 42 Hp (31.3 kW) and 173.6 Nm (128 lb-ft) of max torque at 1200 rpm.

The Case 310B backhoe loader was fitted with three types of transmission. 1st type: 8x8 Dual Range transmission with mechanical shuttle. 2nd type: 4x1 gear transmission. 3rd type: Triple-Range transmission with 12 forward and 3 reverse gears.

The maximum travel speed (forward and reverse): 22.9 mph (36.8 km/h) / 22.8 mph (36.7 km/h). The direct drive hydraulic system includes a gear pump with a rated capacity of 19 gpm (72 lpm). The main relief pressure is 110 bar (1600 psi). The Case 310B is equipped with 7.50x16 front tires and 13.0x24 rear tires. The wheelbase is 75.3" (1910 mm).

The loader’s maximum lift height is 129.8" (3290 mm) at pin and bucket dump clearance is 109.5 (2780). The lifting capacity is 1500 lbs (680 kg) at maximum height (bucket pin), and breakout force (bucket on ground) is 3000 lbs (1360 kg). The estimated cycle times are 6.5 seconds raising to maximum height, and 4 seconds to full bucket dump. The loader is compatible with 48" (1210 mm), 56" (1420 mm), and 63" (1600 mm) buckets.

The backhoe has a maximum depth of 150" (3810 mm). The overall reach from swing pivot at ground line is 194" (4920 mm). The backhoe can be fitted with 14" (355 mm), 16" (405 mm), 19" (480 mm), 24" (605 mm), or 30" (760 mm) buckets.
