Kubota SVL97-2 Troubleshooting
The
Kubota SVL97-2 compact track loader is powered by Kubota V3800-TIEF4 vertical
inline four-cylinder turbocharged liquid-cooled diesel engine with a rated power
of 87 hp (65 kW). The Kubota SVL97-2 is equipped with a 2-speed hydrostatic
transmission, 17.7" (450 mm) rubber tracks, triple flange lower track rollers,
vertical-lift loader boom, and self-leveling bucket. The hydraulic system has a
pump with fluid flow rate of 23 gpm (87.2 lpm) or 40 gpm (151.6 lpm). The track
loader has a rated operating capacity of 4570 lbs (2072 kg) and tipping load of
9140 lbs (4144 kg). The max lift height is 128.5" (3265 mm) to hinge pin, and
bucket breakout force is 7623 lbs (3458 kg).
