Early Allis Chalmers pull grader

I have a Pull Be Hind Power Controlled grader that was sold by Allis Chalmers. There are no decals on it anymore, but you can tell it was an Allis from the shape of where the decal was. It does have a small brass tag on it saying Allis Chalmers Manufacturing Co. and the model number 14508. The design of it leads me to believe that this particular grader was built before Allis took over the Ryan Manufacturing Co. and then sold under the Allis name. Here is a couple pictures:






I have the four cylinder engine for it, but the mounting framework has disappeared long ago. I am trying to get this machine back into working order. I was wondering if anyone has seen or know of another one of these anywhere so I can get pictures of a complete machine.

According  to the good book by Mr. Swinford, you have a number 14 truss-frame power controlled grader (1932). The correct engine is the 100.5 cu.in A-C two cylinder (half a 201 WC engine). I've only ever seen two of these engines. Paul Pelton in Delta Ohio has one. The grader it came from is still in Alaska.

This grader was my grandfathers and he bought it from some mining outfit I would guess in the mid to late 1940's. My dad and I picked the grader up from my great uncles' place and my uncle said that him and my grandfather took the engine out to rebuild it, but never got around to it and stored it in the shed. The engine that I have a four cylinder Le Roi Engine. I don't know if this engine came with this specific grader or not, but it does fit. The only problem is the motor mounting framework is missing. Here are a few pictures of the motor.






I have found the original patent drawings for this type of grader, but they don't show the motor mounting system very well. All I need are a couple of pictures of what the motor mount consists of I can build it myself.

I don't believe they had the parts to rebuild it, but as I was told the engine hardly had an  compression left to operate the controls. I haven't opened the engine up yet to see what it looks like inside. The engine turns over so it is not stuck. I does need new spark plugs, water hoses, fan belt, and some radiator work other than that it is in very good shape.
The grader besides the motor mounts needs 14 new u-joint knuckles which are a three piece design that consists of two fingers with caps welded on collars, 7-8 new u-joints  which the original ones are I believe are cast from lead (the others are a dark gray in color and no corrosion at all), and a few control rods. All these parts go for the controls to offset the tongue and lean the front wheels. the gear boxes on the front need to be taken apart and fixed.

That is a good looking engine Calvin. The grader I have may or may not have had one of those originally. The picture of the engine you posted shows that it is set up for a chain drive mine is set up for a belt drive. It could be that the grader was upgraded to the bigger engine from the factory or where it was delivered. You can see the pulley in the picture. Also another odd thing is fuel tank. The way it is mounted looks like it was placed there as a modification, so it could be that this grader did come with the smaller motor and they modified the grader to have the bigger motor.
