Gehl 3610 Troubleshooting
The
Gehl 3610 skid steer loader is powered by 86.6 cu.in (1.4L) Isuzu 3KR1/QT-35
vertical inline 3-cylinder naturally aspirated liquid-cooled diesel engine with
a rated power of 30 hp (22.4 kW) at 2700 rpm. The Gehl 3610 is equipped with a
radial-lift boom, one-speed hydrostatic transmission, 60H drive chains,
and 5.70x15 or 27x8.50x15 tires. The hydraulic system has a pump with fluid flow
rate of 11 gpm (42 lpm). The hydraulic pressure is 2200 psi (152 bar). The skid
steer has a rated operating capacity of 925 lbs (418 kg) and tipping load
of 1850 lbs (835 kg). The lift height is 102 inches (2590 mm) to hinge pin, and
dump reach at full height is 15.5 inches (395 mm).
