Allis-Chalmers Model G

Going to look at a Model G with seeders and cultivators tomorrow. Been sitting for 4 years out in the weather. I know nothing about A-C tractors so hoping for a little guidance before I go see it. Looks like a fun project tractor. Can anybody tell the approx. year of the tractor from the Craigslist ad? I am quite handy with Fords but I need a new challenge. Thanks in advance for any help

(quoted from post at 21:09:54 08/04/18) only way to tell is going to be with the serial number

Wherabouts is the serial number on those ACG's
Is there a chart available for me to print out before i go see it?
 
Challenge that one would be! Fun, but lots of $$$$$. The hard to find weight on the front end is plus though. I see several nicer ones on Craigslist. It's almost always the case that by putting more money into a better used tractor, you'll end up with a nicer one for less money after all is said and done.
 
Serial number is just behind the gearshift lever and it'll be upside down when looking from the front unless its G #1 (little joke there). Also that is not an original front weight.
 
"Notoriously finnicky starter" is bull. He just didn't know how to set it up. I had the field coils replaced on mine and the guy didn't connect them right. I spins the wrong way. It hand starts so easily that I never fixed the starter. That's quite a project and looks like a lot more than four years in the weather. Common problem on Gs was breaking axle shafts but you can get aftermarket shafts. Continental engine, parts are available but pricey. It's a two-bearing crankshaft so not good for lugging. Front weight is good but that's not original.
 
You will have your work cut out to get it going.And a lot of $$$. I would look for one in better shape
if your set on a G. I have one and there good machine. I use it for gardening.
 
That more than likely will be a firm price for some time way in the future. Fan bearings are exposed to the elements without a hood. I bought one in that condition and I had NAPA rebuild the engine and it cam to a grand total of $1100.00. 1100 and I put it back together. It needed bored and the crankshaft ground.


some pictures at the link to let you see what they are all about. After this one I went out and bought two and a half more as you will find in the pictures.

I have always wanted a A/C G but for that price and the condition it appears to be in I would keep looking. In my area one almost never sees a G let alone one for sale. Reason I want a G is only because they where made in the town I was born in
 
Copied from the serial number chart in the left hand menu.

Year Starting Serial Number
1948 6
1949 10961
1950 23180
1951 24006
1952 25269
1953 26497
1954 28036
1955 29036
The Serial Number is located on top of transmission case, to the rear of the shift lever
 
About 25 years ago I bought a G from an old guy who was moving south. A 1949 in real good condition and when I went to look at it he said there's a second on to go with it. All told I got 2 tractors, cultivators, Mott mower, front snow blower, chains and 2 plows. All for $2K. Haven't done anything with the second one but it's a first year (ser. 1091) 95 complete.
 
I saw it today...liked it... it's all there...needs battery, plug wires, air cleaner top.

I hooked up battery to the starter and cranked to develop normal oil pressure. All looks good with the crankcase oil. Gas tank was dry and slightly rusty. I'm sure carb was gunked up but rebuildable. It comes double seeder units plus a 4' or so bare with cultivator arms. It needs air in the rears but are good . Air needed in the fronts, one front questionable.

I offered the guy 1000 and he said F**k No so I walked away. I'll let him stew on my offer a while and call him up in a week. And see what he says.

I want to take on the project but not for 1500

After your pictures I would change my mind about the price. If I wanted another I would go the 1500 with the seeder.
Spinning over is a good sign but would be expected with a flat head. That engine without a water pump was used in other tractors and factory mules. When over heated they would loose their compression. When they didn't have a lot of hours the pistons could be taken out the bottom with only removing the pan with new rings would be back running. With luck this could make it hard to start because of low compression. On this one I would remove the head and measure the cylinders for wear If you find it to be low on compression. I found it easier to put the rings on the pistons after they had been pushed up from the bottom.

You are correct! The rod will not go thru the cylinder bore because of the pistons small diameter. The point of the post was that the rings can be put back in from the bottom but much easier to remove the head and install the rings on top. If the only cause of the low compression was over heating because of low water you can replace the rings from the bottom.
 
I am not a AC guy but I am familiar with the AC "G" tractors. That one is kind of rare with it being set out for two row with the extra front end spacers. Then the two row planter is rare too. IF that was any where close to the Mid west it would have been sold in under a day at that price. So maybe in your area it is not worth much but I will say if you do not take it let us know. I just might drive out there and try to buy it.

It's a done deal JD Seller...gonna pick it up tomorrow
if all goes as planned. Save your gas money
 
I to am like JD SELLER that tractor is rare. The planter set up and being spread to two rows makes it priced right for me. Wish it was closer to Tennessee. I want to find one and repower it with a KUBOTA diesel engine.
 
Hanover County VA just North of Richmond used to be a big vegetable growing area there were multiple G tractors on about every farm, some set up really wide to plant and cultivate
things like salad greens.One fellow I knew had about 20 G's.Can't tell from the picture but the really wide ones had an extension about 6" long on the end of the original axles.Still run across a lot of them here.
 
O K TF you have a task, find me one with blown up or non running engine, hydraulics would be nice but not a deal killer. Price according to tires, send me an e mail when you get it. Been wanting to come West Virginia or where ever and meet you so here is my chance.
 
Finally found the serial number of this newly purchased Model G. I guess it's a 1948. Am I correct?

I'll look around I'm in Central VA BTW.There was a guy in Luray VA that had a group of G tractors a long with more AC stuff he sold at auction a few years back he had a couple neat ones and they went pretty cheap $1500-$2500 redone and running.Original hydraulics are pretty rare on a G.
 
Yea I have seen a few with hydraulics but that would not be a deal killer, Since I am going with Kubota motor would have the pump and think I could rig the valve and cylinder. Just keep your eyes out, might want to come up that way if you find a bargain.
 
A good conversion would be a lift system like is on my Hines H-1600 Cat 0 3pt on both center and rear lifts with a separate control for both.A Hines would be very easy to make a diesel conversion as
its a hydrastat drive.
 
Congratulations, I envy you. Don't think I'll ever find one, there were few in my area. For some reason, I do have a G plow, can't even remember where I got it.

Does that plow mount on the back somehow? Mine has the manual lift arm and bracket to attach the cultivator frame. Wonder if the plow attaches to that.

This is sure a sweet running machine once I got the carb and the gas tank cleaned out. Transmission and clutch work. The brake linkage and maybe the linings are really sluggish so I guess I take that apart.

Overall a good deal at 1500 with the cultivator stuff and the seeder pots
 
I've never seen it mounted but I assumed it's belly mount. I'll take some photos when the sun is back out tomorrow and maybe someone can identify how and even if. I would imagine I took the word of the fellow I got it from because I would not have known. I never followed Gs much even though I'd like to have one.

Yes, then you did get a good price. Those rear tires look pretty good. I sure would have paid that or more if local here. It looks like they would be much easier to work on than any other AC.

I had an N62 on an MH Pony we used for cultivating and grinding (pig feed), the engine was tired and it was still a trooper.

I would love to see the photos of that plow. I would think the plow would mount on the back but I may be wrong.

The rear tires are near perfect but the fronts are near rotten so I will be buying two new fronts and tubes. They're 4.00-12 tires and ice seen then on Amazon for $100 for the pair plus tubes... and free shipping.
 
Almost everything on a G mounts in the middle, the rear drawbar is very lightweight and bolts to the block!
About the only thing mounted to the rear are the set of cultivators that take out the tire tracks

Thanks Joe
 
I'll be darned, that plow looks very similar to the one I have that was supposed to be for a G. Just shot a picture of it for nashranch. Interesting that I have two sets of mounts and coulters, everything but the 2nd moldboard. I bet it was a two way and you actually could have one for each direction.

It was healthy, I haven't looked at it for a few years, and if I don't do something to clean it up, it will be junk soon. It appears this plow is the left side for the right side one shown in JD Sellers photo.
 
Chris they did make a one way setup for them but I could not find a picture of them on the net. It was a left and right hand plow on the front. Manual lift for each side. They did not make the hydraulic lift for the one ways. IRC

The reason I have seen a just about every attachment you can get for an AC "G" is my Great Aunt lived in an area of south-eastern Wi that grew lots of vegetables for Chicago. Her husband was an AC dealer. I can remember him having truck loads of AC "G" tractors setting there for sale when they were new. He also had one of every attachment AC made on hand to sell the small truck patch farmers in his area. My Mother and us kids would go up every summer and help them harvest their own truck farm Vegetables. We would be there for several weeks. It was also kind of our summer vacation.

He even had a fair number of attachments that where made by other companies for the AC "G". The most unusual one I saw he had a small roller bar hay rake that was mounted under the middle of the G. That one is the only one I have ever heard of. HE said it did not work very well because if the hay was very tall/thick the windrow would get too big and catch on the belly of the tractor. It was only 5-6 foot wide. It was Belt driven off the motor.

Also do the AC "G" out you way have the front weight on them?? All of the ones he had on his lot did. The ones I see back in The Ohio river valley that cultivated tobacco usually had them too. The ones I am seeing at the mid west show rarely do and most of the time do not have any attachment under the tractor either. I think that would make them very front end light. I can remember them popping the front ends up even with the weight if you let the clutch out too fast/hard.

Pictures shows one of the Gs with a weight on it.

No, the one nashranch bought is the first one I've seen with a weight on it. Like I said though, the only ones I've seen have been at shows. In the last 30 years, I've only heard of 3 in my county and missed the opportunity to buy all three. In the future, if I see one, I'll definitely grab it.
 
Have never paid any attention to a Hines but guess I will go t looking now. Just have several 15 to 45 hp engines, looking for a winter project.
 
They were built in Rocky Mount NC less than 500 total built,I have 3 of them.If you find one with the tiller you hit the jackpot as only 5 tillers were sold.I have a pretty rare belly blade,couple sets of cultivators,plows and rotary mowers that were sold for them.Power King 3pt equipment work good on them.
 
This G Bug has suppression wires on it with a ohm reading around 5-7000 ohms on them. I am wondering if this tractor should have solid copper wires on it. It seems to b running rich and the plugs are a sooty black where #3 is a wet sooty black. Timing has been set to TDC on #1. Plugged are gapped at .030 and points gapped at ,020

This tsx has no hi speed adjustment.. could this be my rich condition?

I just pulled out the plugs and the #3 hole looks wet inside while the others are a dry sooty black

Compression on all the cylinders are an even 90-95 lbs

Air cleaner has been scoured so it's good and clean

Unless it has electronic ignition on it yes the plug wire should be true wire plug wires not the type your saying it has and could well be part of your problem.

That third plug over from the left was not firing so i was loosing 25% power. Put in another old plug i had and wow what a difference. Think now i have 11 horses operating. Tomorrow i get new plugs and solid core plug wires
 
waiting now for brake parts so onto the cultivator frame. I rec'd this cultivator frame and a bunch of sweeps with the purchase of this G Bug. I have no idea if it's AC brand or some other brand. I cannot figure out how this mounts to the mid section of the G. Any help would be appreciated. It does have signs of green paint on it so maybe John Deere brand...dunno

Interested in selling that plow for the "G" bug YTSupport?

I assume yer in Washington State, I down in Oregon but a road trip is in order
 
I haven't totally given up hope on finding a G yet... but I'll think about it, I don't normally sell anything. I would point out, the thing is not worth anything in it's condition, certainly not the gas price from Oregon. I don't know if they are hard to find, but I'd advertise for one that doesn't have all the pitting on the moldboard, has both plows, and free coulters and mounts. Both mounts and the coulters are all rusted solid.

Mine is For Sale down here

Thanks for the offer, but I don't dare, I have 5 tractors awaiting rebuild and restoration. The G is something I'll be looking for later. If I get too far ahead of myself (and I may already be there), I slow down my enthusiasm as it gets overwhelming.

The "G" Bug is in the paint shop now getting its finally cleaning before I paint it. Hopefully it turns out ok

Start tuned for painted pics

That'll be great to see. When the paint goes on, that's the point where the light at the end of the tunnel finally shows up. On my current restoration (D17D), I'm just starting and haven't had the time to work on it. It's getting rebuild, paint, front tires, rewire and some hydraulics work.
 
Paint Job on the body turned out real good...working on rear wheels, sheet metal and cultivator parts now in spare time

Been a fun project. It's finally coming to an end. Been working on a lot of other projects but got back to the ole G Bug. Hopefully I get it all done for spring time

Beautiful. Sure feels good to get it done I bet. Unfortunately, that means it's time to start the next one.
 
Quick question on the firing order. Is it still 1-3-4-2... number one being towards the rear? I had it wired 1-4-3-2 and it didn't seem to run quite right so I shut it down and came in house to check on tractordata.com. Now with it hooked up 1-3-4-2 it won't start. I bet I have it flooded now.
