ASV RC-30 Troubleshooting
The
ASV Posi-Track RC30 compact track loader is powered by 92 cu.in (1.5L) Perkins
403D-15 3-cylinder indirect injection liquid cooled diesel engine with a rated
power of 31.5 hp (23.5 kW). The ASV RC-30 is equipped with a
single-speed hydro transmission, radial-lift loader boom, 11" (280 mm) rubber
tracks with embedded co-polymer cords, and elevated track drive sprockets. The
hydraulic system has a pump with fluid flow rate of 10 gpm (38 lpm). The
hydraulic pressure is 3000 psi (207 bar). The track loader has a rated operating
capacity of 560 lbs (255 kg) and tipping load of 1600 lbs (725 kg). The maximum
lifting height is 80.3 inches (2040 mm) to hinge pin.
