The Allis Chalmers 170 was manufactured from 1968 to 1973, and about 9,300 were released. The AC 170 was produced in order to replace the D17, however a few components were transferred to the new 170, including the Power Director, transmission, and Traction Booster.
The 170 came in two fuel-types: diesel and gasoline. The diesel model engine came from English manufacturer Perkins. It was liquid-cooled, had four cylinders, a bore and stroke of 3.875×5 inches, displacement of 236ci, and a compression ratio or 16:1. The Allis Chalmers gasoline model was also four-cylinders, but the outputs were quite different. The gasoline engine had a bore and stroke of 4×4.50 inches, displacement of 226ci, and a compression ratio of 8:1. When the engines were tested, the diesel model had a PTO power of 54.04 horsepower and a maximum drawbar power of 47.39 horsepower. The gasoline engine, however, had a PTO power of 54.12 horsepower and a maximum drawbar power of 46.93 horsepower.
The transmission that Allis Chalmers transferred from their D17 had eight forward gears, and two reverse gears. It was controlled by both a gear shifter and a Power Director. To use the clutch, the tractor had to be stopped first, but the Power Director could be shifted while the tractor was moving. If the Power Director was placed in neutral, it kept the PTO engaged while the tractor was stopped.
The serial number on the Allis Chalmers 170 is located on the front of the torque housing flange, and the production year corresponds as follows:
1969: 5374
1970: 6369
1971: 6988
1972: 7797
1973: 8821
