Case TR310B Troubleshooting
The
Case TR310B compact track loader is powered by 207 cu.in (3.4L) FPT F5H FL463
vertical 4-cylinder direct injection turbocharged diesel engine with a rated
power of 74 hp (55 kW) at 2500 rpm. The Case TR310B is equipped with a two-speed
hydrostatic transmission, dozer-style undercarriage, and 15.7" (400 mm) rubber
tracks with steel inserts. The hydraulic system has a pump with fluid flow rate
of 24.2 gpm (91.5 lpm). The hydraulic pressure is 3050 psi (210 bar). The track
loader has a rated operating capacity of 2170 lbs (984 kg) and tipping load of
6200 lbs (2812 kg). The lift height is 125.1" (3180 mm) to hinge pin, and dump
height is 100.6" (2560 mm).
