Case IH 1694 Troubleshooting
The
Case IH 1694 tractor was manufactured from 1985 to 1988. The Case IH 1694
driveline system components: AD6.55T 6 cylinders direct injection turbocharged
diesel engine and Hydra-Shift partial powershift transmission with 12 forward
and 4 reverse gears.
A 329 cubic inches (5.4 L) engine power rating is 112 hp (83.5 kW), and max. torque is 396 Nm (293.3 lb-ft) at 1600 rpm. Max. travel speed (forward/reverse): 19.7 mph (31.7 km/h) and 11.6 mph (18.7 km/h). The open center hydraulic system used a gear pump with fluid flow rate of 10.5 gpm (39.8 lpm).
The hydraulic system pressure is 180 bar (2600 psi). The Case IH 1694 tractor is equipped with a hydrostatic steering system, disc brakes, 13.6x28 front tires, and 16.9x38 rear tires. The wheelbase is 100 inches (2540 mm).
