A.C. D road grader

I have a Allis Chalmer motor grader "D" (D4787) Can someone tell me the original color for these grader, most of the one I seen are yellow but A.C. color is orange and speed graders are orange did they paint road machinery yellow also bought a parts grader (D2407) no paint and looks like it had a bucket attatchement in the back, was this a A.C.option or other maybe home built not enouph left to see but what is there doesn't look homemade. Just bought another one didn't see it yet but the price was to good to leave it there. Like they say it followed me home.Bob

Bob, if you look under reserch and info you will see the subject of paint codes. Yellow, orange and cream were used. You and I both had machines follow us home. One D was painted yellow, orange and blue (different layers of paint underneath now all yellow that is all I could find at the time) the other is all Persian Orange. I believe you have a neighbor that also has one and he was lookin for parts for his. Maybe you 2 can get together and deal. I will try to look for his name.

A friend of mine had 2ALLIS grader and these was creme and had DETROIT motor in

According to my serial number list the newer grader is a 1956 model and the older grader is a 1952 model. My grader according to serial number is a 1959 model and it is painted Persian orange. I think that most of the older Allis construction equipment was orange with yellow as possibly a special order. I have the original parts book for mine which also shows the breakdown of of parts for all the options that were available. There is a rectangular opening with a rubber seal on the left rear side of the cab on mine that was intended for the hydraulic lines for a rear mounted loader. Apparently there is a D grader with a loader at a municipal museum in either Sask. or Man. I can't see that the loader would have been very practical as these suckers take about 40 acres to turn around plus they would be very uncomfortable to operate. I don't think that Allis made the loaders.
I have made a few modifications to mine. I have moved the hydraulic pump to drive off the end of the crankshaft. I am just in the process of finishing off my power steering installation. I replaced the manually adjustable side shift linkage with a hydraulic cylinder since I don't have a shift-able moldboard.
It is great that you have saved some parts machines. People are always looking for parts. I myself am trying to find an angle drive for the power circle so that I can convert my machine to a power circle.
