Mustang 2109 Troubleshooting
The
Mustang 2109 skid steer loader is powered by Perkins 1104C-E44T 4-cylinder
direct injection turbocharged liquid-cooled diesel engine with a rated power of
115 hp (86 kW) at 2400 rpm. The Mustang 2109 is equipped with a radial-lift
boom, one-speed or two-speed hydrostatic transmission, 100HK drive chains, and
14x17.5 tires. The hydraulic system has a pump with fluid flow rate of 29 gpm
(110 lpm) or 40 gpm (151.5 lpm). The hydraulic pressure is 3300 psi (228 bar).
The skid steer loader has a rated operating capacity of 3675 lbs (1724 kg) and
tipping load of 7350 lbs (3335 kg). The lift height is 142" (3605 mm) to
hinge pin, and dump height is 107" (2720 mm).
