Bobcat T200 Troubleshooting
The
Bobcat T200 compact track loader driveline system components: a 178 cu.in (2.9L)
Deutz BF4M1011F 4-cylinder turbocharged liquid-cooled diesel engine with a rated
power of 73.5 hp (54.8 kW), and single-speed hydrostatic transmission. The
hydraulic system has a pump with a rated flow of 20.5 gpm (78 lpm) or 32 gpm
(121 lpm). The Bobcat T200 is equipped with a radial-lift loader boom, 12.6"
(320 mm) or 17.7" (450 mm) rubber tracks, bob-tach system, and wet-disc brakes.
The loader has a max lift height of 121" (3075 mm) to hinge pin and dump height
of 91.5" (2325 mm). The rated operating capacity is 2858 lbs (1296 kg), and
tipping load is 5716 lbs (2592 kg).
