New Holland L325 Troubleshooting
The
New Holland L325 skid steer loader driveline system components: FPT F5C E5454
four-cylinder direct injection turbocharged diesel engine with a rated power of
76 hp (57 kW), and 1-speed or 2-speed hydrostatic transmission. The hydraulic
system has a pump with a rated capacity of 22.5 gal/min (85 l/min) or 34.5
gal/min (131 l/min). The New
Holland L325 is equipped with a vertical-lift boom, ASA 100 drive chains,
and 12x16.5 standard tires. The skid steer loader has a max lift height of
129.5" (3290 mm) to hinge pin and dump height of 103" (2615 mm). The rated
operating capacity is 2500 lbs (1135 kg), and tipping load is 5000 lbs (2270
kg).
