Mustang 2099 Troubleshooting
The
Mustang 2099 skid steer loader driveline system components: a 269 cu.in (4.4L)
Perkins 1104C-44 4-cylinder direct injection liquid-cooled diesel
engine with a rated power of 86 hp (64 kW), and 1-speed or 2-speed hydrostatic
transmission. The hydraulic system has a pump with a rated capacity of 29
gal/min (110 l/min). The system pressure is 3300 psi (228 bar). The
Mustang 2099 is equipped with a radial-lift boom, 100HK drive chains, and
14x17.5 tires. The skid steer loader has a max lift height of 142" (3605 mm) to
hinge pin and dump height of 109.5" (2780 mm). The rated operating capacity is
3400 lbs (1542 kg), and tipping load is 6800 lbs (3085 kg).
