Allis Chalmers WD45 Tractor Parts

About the Allis-Chalmers WD45

The WD45 replaced the WD in 1953 and gave Allis-Chalmers a stronger four-plow row-crop tractor without losing the WD's live PTO and Snap-Coupler layout. Its 226-cubic-inch gas, tractor-fuel, or LP engine made it noticeably more powerful than the WD.

The WD45 was the first Allis-Chalmers tractor offered with power steering, which became available in 1956. A six-cylinder diesel was added after Allis-Chalmers acquired Buda, and the WD45 remained in production through 1957.

Serial Number Reference

Serial number locations: The tractor serial number is stamped at the left brake cover or the left rear of the axle housing. The gasoline engine serial number is on the left-hand side of the engine near the carburetor; diesel engine numbers are on the left-hand side of the diesel engine.

The table below shows the beginning tractor serial number for each Model WD45 year:
