Case IH 1294 Troubleshooting
The
Case IH 1294 farm tractor was manufactured between 1984 and 1985. The components
of Case IH 1294 powerline system: AD4.55 4 cylinders direct injection
water-cooled naturally aspirated diesel engine and mechanical synchromesh
transmission with 12 forward and 4 reverse gears.
A 219.1 cubic inches (3.6 L) engine has a cylinder bore of 3.94" (100 mm), piston stroke of 4.49" (114 mm), rated power of 62 hp (46.2 kW), and 223 Nm (165.1 lb-ft) maximum torque at 1250 rpm. Max. travel speed (forward and reverse): 19.7 mph (31.7 km/h) / 11.6 mph (18.7 km/h).
The open center hydraulic system used a gear pump with rated fluid flow of 7.8 gal/min (29 l/min). The hydraulic system pressure is 176 bar (2550 psi). The Case IH 1294 was equipped with a hydrostatic power steering, mechanical drum brakes, 7.50R16 front tires, and 13.6R38 rear tires. The wheelbase is 82.7 in (2100 mm).
