Kubota SVL65-2 Troubleshooting
The
Kubota SVL65-2 compact track loader is powered by Kubota V2607-CR-TE4
four-cylinder turbocharged diesel engine with a rated power of 62.5 hp (46.6 kW)
at 2600 rpm. The Kubota SVL65-2 is equipped with a two-speed hydro transmission,
12.6" (320 mm) or 15" (380 mm) rubber tracks, triple flange lower track rollers,
vertical-lift boom, and self-leveling bucket. The hydraulic system has a pump
with fluid flow rate of 17.4 gal/min (66 l/min) or 27.1 gal/min (102.7 l/min).
The track loader has a rated operating capacity of 3000 lbs (1360 kg) and
tipping load of 6000 lbs (2720 kg). The max lift height is 118.5" (3010 mm) to
hinge pin, and breakout force is 4614 lbs (2093 kg).
