Takeuchi TL12R2 Troubleshooting
The
Takeuchi TL12R2 compact track loader is powered by Kubota V3800-CR-TI-F4B
4-cylinder turbocharged liquid-cooled diesel engine with a rated power of 112 hp
(83 kW) at 2400 rpm. The Takeuchi TL12R2 is equipped with a two-speed
hydrostatic transmission, radial-lift boom, hydraulic self leveling, 17.7" (450
mm) rubber tracks, and track rollers with metal face seals. 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 4315 lbs (1958 kg) and tipping
load of 8630 lbs (3916 kg). The max lift height is 126" (3200 mm) to hinge pin,
and bucket breakout force is 8210 lbs (3720 kg).
