Ford 7710 Tractor Troubleshooting
The
Ford 7710 is a 10-series row-crop tractor. This model was manufactured between
1982 and 1990. The Ford 7710 is powered by 268 cubic inches (4.4 L) Ford 4-cycle
four-cylinder liquid-cooled diesel engine with a maximum output power of 97 hp
(72.3 kW) and 377 Nm (278 lb-ft) of peak torque at 1400 rpm.
The Ford 7710 tractor is equipped with three types of transmission. Type
1: 8x2 Dual-Range transmission. Type 2: 16x4 Dual-Power partial power
shift transmission. Type 3: 16x8 synchromesh partial powershift
transmission. Max. travel speed (forward and reverse): 19 mph (30.6
km/h) / 9 mph (14.5 km/h).
The open center hydraulic system used a gear pump with fluid flow rate
of 18.2 gal/min (68.9 l/min). The hydraulic pressure is 172.5 bar (2500
psi). The 2WD models are equipped with 7.5x16 front tires and 15.5x38
rear tires. The 11.2x24 front tires and 18.4-30 rear tires are used for
4WD tractors. The wheel base is 101.6" (2580 mm) for 2-wheel drive
models and 97.6" (2470 mm) for 4-wheel drive models.
The Ford 7710 is compatible with a Ford 777B loader with lift capacity
to full height of 2500 lbs (1134 kg), Ford 777D loader with lift
capacity to max height of 2900 lbs (1315 kg), or Ford 7412 loader with
lift capacity to full height of 3000 lbs (1360 kg).
