Takeuchi TL8 Troubleshooting
The
Takeuchi TL8 compact track loader is powered by 203.2 cu.in (3.3L) Kubota
V3307-CR-T 4-cylinder turbocharged diesel engine with a rated power of 74.3 hp
(55.4 kW) at 2400 rpm. The Takeuchi TL8 is equipped with a hydrostatic
transmission, radial-lift loader boom, hydraulic self leveling, 15.7" (400 mm)
or 12.6" (320 mm) rubber tracks, and permanently sealed track rollers. The
hydraulic system has a pump with fluid flow rate of 18.4 gpm (69.5 lpm) or 33
gpm (125 lpm). The track loader has a rated operating capacity of 3010 lbs (1365
kg) and tipping load of 6020 lbs (2730 kg). The lift height is 119.3" (3030 mm)
to hinge pin, and dump height is 93.3 inches (2370 mm).
