Takeuchi TL240 Troubleshooting
The
Takeuchi TL240 track loader is powered by Yanmar 4TNV98T 4-cylinder direct
injection turbocharged liquid-cooled diesel engine with a rated power of 83 hp
(61.9 kW) at 2500 rpm. The Takeuchi TL240 is equipped with a 2-speed hydro
transmission, radial-lift boom, hydraulic self leveling, 17.7" (450 mm) rubber
tracks with steel inserts, and permanently sealed track rollers. The hydraulic
system has a pump with fluid flow rate of 20 gpm (76 lpm) or 36.2 gpm (138 lpm).
The track loader has a rated operating capacity of 2975 lbs (1350 kg) and
tipping load of 5950 lbs (2700 kg). The max lift height is 123.1" (3120 mm) to
hinge pin, and bucket breakout force is 7400 lbs (3355 kg).
