Case IH 2140 Troubleshooting
The
Case IH 2140 is a 2-wheel drive or 4-wheel drive orchard/vineyard tractor from
2100 series. This model was manufactured by Carraro built between 1988 and 1993.
The Case IH 2140 tractor is powered by SLH 1000.4A 4-cycle 4-cylinder air-cooled
diesel engine with a max output power of 61 hp (45.2 kW) and 233 Hm (172 lb-ft)
of max torque at 1200 rpm.
The Case IH 2140 is fitted with 2 transmission options: 8x8 partially synchronized transmission, or 12x12 partially synchronized transmission. Max. forward and reverse speed - 18.1 mph (29.2 km/h).
The open center hydraulic system used a gear pump with a flow of 15.6 gal/min (59 l/min). The 2-wheel drive models are equipped with 7.50x16 front tires and 13.6R28 or 14.9R28 rear tires. The 8.25x16 or 7.50x18 front tires and 13.6R28 rear tires are used for tractors with 4-wheel drive. The wheelbase is 83.1" (2110 mm) for 2WD models and 81.7" (2070 mm) for 4WD models.
