Hello and motor grader questions

Hello. I came across this site while looking for info on a motor grader project I'm looking to start.

I have a 1949 Allis Chalmers D model grader that I would like to make run to maintain my driveway. This grader came with the property when I bought it. It was parked around 10 years ago and may have had parts taken from it for other things.

The engine will turn over. It doesn't have a lot of compression, but I've got some marvel oil in the cylinders, hopefully that'll help.

The question I have is how is the ignition supposed to be wired? Does it need a coil? The only thing wired up is the starter motor.

I appreciate all the info I can get, thanks in advance.
 
Where are you located? I've seen the members of this site be very helpful. Also, you might post this in the Allis Chalmers forum. You might get quicker help there...Good luck, and welcome!
 

I'm in central New Mexico. Been having a heck of a time finding much info on this machine. I'll post a few questions in the proper place. Thanks.
 
Too much to type but if you will open your e-mail I can give you a short course on how to wire it just to see if it will run. Won,t take much.
 
If it has the original electrical system, it will have a magneto on the 6 volt system. Coil would be inside the magneto.
 
There are a few D grader blokes active over at

Drop on down a few forums to the A.C. forum (on this site) or give a shout out for OLD. He has an AC grader & can be dog gone helpful with your problems. Keith
 
Thanks everybody.

Has been changed to 12 volt. Has a Bosch American magneto that I don't think is original.

I think I opened my email thing, a quick wiring lesson would be appreciated.

I got my username from the song. Used to have one of the same hobbies.
 
basically if all you are trying to do at this time is make it run you really don't any wiring. You can use a set of jumper cables to turn it over and a Magneto makes it's own power. What's to wire until after it runs and he decides to fit it?

Yes, right now all I want it to do is run. I don't know anything about this thing. I just needed to quit over thinking things. It's just like my snowmachine, just bigger. I did get it to turn over and fire, I think I'm going to have to pull the carb off.
 
I don't know much about the allis, but if it turns over
your half way there, clean up the mag and carb, and
should be able to get it going. I live in northeastern
NM, Clayton always nice to hear from a fellow New
Mexican lol

Gee, I am looking for a AC model D grader, and I have land in Northern NM. Coinkeedink!

There are several types of magnetos that will fit on the grader. The engine is basically the same as an AC W or WC or WD engine(not exact, but the mags will cross).

Here's a couple links to help.

This guy is the Wico expert, if it's a Wico type, I would just take it off, send it to him with a check and then install:

Figure out which you have and go from there. As for the carb, if it's been sitting for a while, find the code on the side of it; "TSX-451" or something like that, and order a rebuild kit from this site. Clean it completely, and do the rebuild. With the mag and carb going, you might be in business.

Let me know when I can come by and borrow it for my place up in Costilla. hehehee!
 
I forgot to mention, these machines are notorious for gunk in the fuel tank. Be cautious about what comes out of that tank. It would benefit greatly to drain, clean, and check it carefully before going further. When I've been shopping for one if these, many of them use a remote mounted fuel tank due to rotting crud in the grader tank. Also will need a couple of fuel filters in line if you maintain the stock fuel tank.
 
You guys are great. I never expected to get this much help, especially so fast. I hope I can help some time.

It's cool to already know that there is at least 2 people from the same state as me.

I did clean the gas tank, it was pretty nasty. I put 10 pounds of stainless steel pins for my brass tumbler, hot water and Dawn dish soap in it and shook it until my arms were tired. I got it pretty clean and there isn't much rust in it. I want to get it running so I can move it closer to the shop.
 
Good luck running a grader if you are not an experienced operator. Dig too deep ,too light ,too deep , too light . Watch the blade ,the horizon and the cut all at once . I takes weeks to train the eyes for a grader.

I'm not going to be building any roads or grading big pads, just be spreading a little gravel, moving snow, and using it to smooth out my rifle range a little.
 
I agree. My son restored a Huber maintainer. I have found that it only takes about 15 seconds to screw up my driveway to the point that it takes about 2 hours to fix.
