Allis Chalmers IB Tractor Parts

About the Allis-Chalmers IB

The IB was Allis-Chalmers' industrial version of the Model B. It kept the compact four-cylinder layout but added a heavier frame and front axle, along with a foot throttle for industrial work.

IB tractors built before 1946 shared the serial-number sequence used by the farm Model B. From 1946 onward, the IB used its own IB-prefixed serial numbers, and the model continued into the 1950s.

Serial Number Reference

Serial number locations: The tractor serial number is stamped behind the gear shift lever on top of the transmission case. The engine serial number is on the rear left-hand side of the engine between the carburetor and fuel filter.

The table below shows the beginning tractor serial number for each Model IB year:
