ASV RT-25 Troubleshooting
The
ASV Posi-Track RT-25 compact track loader is powered by 103.7 cu.in (1.7L)
Perkins 403J-17T 4-cycle vertical in-line 3-cylinder indirect injection
turbocharged diesel engine with a rated power of 24.7 hp (18.4 kW) at 2800 rpm.
The ASV RT25 is equipped with 1-speed hydrostatic transmission, axial-piston
drive pumps, and 11" (280 mm) rubber tracks with embedded co-polymer cords. The
hydraulic system has a gear pump with fluid flow rate of 11.3 gpm (42.8 lpm).
The hydraulic pressure is 3000 psi (207 bar). The track loader has a rated
operating capacity of 665 lbs (302 kg) and tipping load of 1900 lbs (862 kg).
The max lift height is 101" (2565 mm) to hinge pin.
