Hello let me say first of all I'm new here. I was wondering what is the difference between a Allis Chalmers WD and WD45. This may be a stupid ? but I want to be sure what I have. Thanks

Basically, A WD has a smaller engine and a large plate bolted to the right side of the engine. It can have a straight shift lever, however late models had a curved shifter.

A WD is 35hp and a WD45 is 45hp, A WD45 motor will have a serial number on the block that starts with 45-XXXX. A WD motor has a bolt on plate on the right side if I remember right. WD transmission will have a straight shift lever (except a 53 model) WD45 will have a curved shift lever. Also the only stupid question is the one that is never asked. Hope that helps

WD-45s had distributor ignition, a different transmission with a curved gear shift and helical cut gears, these changes occurred on late production WDs as well.  The most important difference is a 226 cubic inch engine.  The engine has no lifter cover, like a WD or WC engine dose.  They are also called power crater engines, because the combustion chamber is on built into the top of the piston.  I hope this helps.

Thanks everyone good info!! So let me throw this one out there I have a chance to buy a WD or WD45 not sure yet going to look at it tomorrow. I do know however that it's a one owner and things as they should. It has like new tires, pto, three point hookup/not converted. It needs to be painted. What would be a fare price for this.

$1200 for a WD, up to $1800 for a WD45.  They never came with a factory 3pt.....

The three point is reversed of what you need for modern implements. Correct?

AC developed their own hitch system called the "snap coupler"  which is a very good system combined with their "traction booster" which transferred weight to the tractor. When the 3pt patents ran out, they were pretty much forced to change to the 3pt arrangement on later model tractors.  Their are AC and aftermarket 3pt conversion kits available. You need these conversions to use 3pt implements.

The "three point" as you call it is called Snap Coupler.  With implements made for it it is the best mounted implement hook up there is.  What all do plan to use the tractor for?  Most 3 point equipment can be adapted to snap coupler.  The snap coupler is a unique to Allis system.

Is it wide front, narrow front, power steering or not, the only factory 3point Allis ever had was an Oxnard 3point that you could order with the tractor or the aftermarket you get nowadays. P/S will add $500 to the price, wide front will add $400 to $500 to the price. The factory wide front is a square tube, not round

I plan on using a box blade/grader, and a bushog. 


Posted By: Joe(OH)

Well you can get an AC blade for your grader needs, if you can find it you could get a snap coupler bushhog, or convert one to snap coupler.  Worst case scenario is use a pull type bushhog.  Good luck!

The serial number is the real determining factor. 146606 is the last WD. 146607 is the first WD45. It's stamped into the left rear side of the rear axle housing. Might have to scrape off some paint to find it. New tires is a big plus. I spent $450 ea for rear tires for my D17.

Man, Brian is right there on the tires! Tires are a big plus on tractors because of the big hit in the wallet! Best way to ID the machine is the serial number. Coarse the side lifter plate is usually a dead give-away on a straight WD. Don't always go by the Mag or Distributor senerio either. It could have been changed sometime in its lifetime from Mag to Distributor if its a WD. Either way, you probably can't go wrong which ever model it is......

Randy, is the oxnard 3-pt you refer to the snap coupler to three point adaptor or an actual 6-pt on the tractor without removing the drawbar?  Thanks, Dave

Randy Mo You might want to qualify your statement,( the only factory 3point Allis ever had was an Oxnard 3point that you could order with the tractor or the aftermarket you get nowadays.) to tractors prior to the late D series.

Serail # is realy the only way to tell. As Steve has said alot of changes are made over the years to these tractors. My dads WD has a curved shifter which I think is factory. The shifters are very easy to change over and many have been changed to the curved shifter. The WD block will have a plate about 18" high and the length of the block on the right side, WD45 will not. Again did somebody swap out the motor?
