ASV RC-85 Troubleshooting
The
ASV Posi-Track RC85 compact track loader is powered by 269 cu.in (4.4L) Perkins
1104C-44 vertical four-cylinder direct injection diesel engine with a rated
power of 86 hp (64 kW). The ASV RC-85 is equipped with a single-speed
hydrostatic transmission, radial-lift loader boom, axial-piston drive pumps, and
suspended undercarriage with 18.7" (475 mm) rubber tracks. The hydraulic system
has a pump with fluid flow rate of 20 gpm (76 lpm). The hydraulic pressure is
3300 psi (227 bar). The track loader has a rated operating capacity of 2380 lbs
(1080 kg) and tipping load of 6800 lbs (3085 kg). The maximum lift height is
125" (3175 mm) to hinge pin.
