Allis Chalmers I40 Tractor Parts

About the Allis-Chalmers I40

The I40, also written I-40, was an Allis-Chalmers industrial tractor built in West Allis, Wisconsin, from 1964 through 1966. Its four-cylinder 2.4-liter gasoline engine was rated at 40.6 horsepower. Two-wheel drive, power steering, and loader and backhoe equipment made it suitable for utility and construction work.

The I400 followed the I40. Check each part listing for the correct model, engine, and any serial-number restrictions before ordering.
