John Deere 317G Troubleshooting
The
John Deere 317G compact track loader driveline system components: a 128.1 cu.in
(2.1L) Yanmar 4TNV86CHT 4-cylinder turbocharged diesel engine with a rated power
of 61 hp (45.6 kW), and single-speed hydro transmission. The hydraulic system
has a pump with a rated flow of 17 gpm (63 lpm). The system pressure is 3450 psi
(238 bar). The John Deere 317G is equipped with vertical-lift loader boom, wet
disc brakes, and 12.6" (320 mm) or 15.8" (400 mm) rubber tracks.
The loader has a boom lift force of 5250 lbs (2385 kg) and bucket
breakout force of 6000 lbs (2725 kg). The rated operating capacity is 2125 lbs
(965 kg), and tipping load is 6070 lbs (2756 kg).
