Takeuchi TL12V2 Troubleshooting
The
Takeuchi TL12V2 compact track loader is powered by 230 cu.in (3.8L) Kubota
V3800-CR-TI-F4B 4-cylinder turbocharged liquid-cooled diesel engine with a rated
power of 112 hp (83 kW). The Takeuchi TL12V2 is equipped with a 2-speed
hydrostatic transmission, vertical-lift boom, hydraulic self leveling, 17.7"
(450 mm) rubber tracks, and permanently sealed track rollers. The hydraulic
system has a pump with fluid flow rate of 23 gpm (88 lpm) or 40 gpm (153 lpm).
The track loader has a rated operating capacity of 5870 lbs (2663 kg) and
tipping load of 11740 lbs (5326 kg). The maximum lift height is 130" (3300 mm)
to hinge pin, and dump height is 96.8" (2460 mm).
