Takeuchi TL140 Troubleshooting
The
Takeuchi TL140 compact track loader driveline system components: a 186.7 cu.in
(3.1L) Isuzu 4JG1T 4-cylinder direct injection turbocharged liquid-cooled diesel
engine with a rated power of 81 hp (60 kW), and two-speed hydrostatic
transmission. The hydraulic system has a pump with a rated flow of 19.8 gpm (75
lpm). The Takeuchi TL140 is equipped with a radial-lift loader boom, 17.8" (450
mm) rubber tracks, hydraulic disc brake, and hydraulic self leveling. The loader
has a bucket breakout force of 7400 lbs (3365 kg) and maximum lift height of
122.9" (3115 mm) to hinge pin. The rated operating capacity is 2975 lbs (1345
kg), and tipping load is 5950 lbs (2690 kg).
