Getting an A-C G, what should I look for?

Haven't used old orange equipment in almost 20 years, and that was a WC. Just last week heard of a deal through the grape vine on a G that would be a good useful addition to our little farm. I'm told it's been stored inside for years, motor is free, but doesn't run. I'll be going to check it out this weekend. I'll be taking a battery and compression gauge. I know it's a tiny motor, but what are good numbers for compression?

What else goes wrong with these that I should look at and for? Transmission? Brakes? If I remember it right, seems I heard the axle splines can strip. How bad are parts to find, and where does one look (other than here :) )

Unless I can make a sweet offer, it probably won't come with implements as they indicated they want to keep spares for the other G's they have and use. I'll assume it will need new tires.

In the far more experienced wisdom here, what's a fair ballpark price if everything else seems sound, and what would be the deal breakers?

TIA

I have bought three non running G's and gave 1100.00 for each. It will Probly need rings. One of the big things with that engine without a water pump is that when low on water they get hot and it takes the tension out of the rings. When that happens all that is needed is rings. Rings in that engine can be installed by only removing the pan. Removing the head would not help as the pistons will only come out the bottom of this engine.
 
check the drawbar support. These are delicate and
are not to be used to pull anything. It doesn't
take too hard of a pull on the U shaped support and
the block will break at the bottom screw holes. I
have 2 G's and 1 had the block cracked there. LOL

Thanks for the replies.

Dick L, seems odd indeed that pistons only come out the bottom, and is there room to work a ring compressor in the bottom end of a tiny block to get a re-ringed piston back in without pulling the crank?

ChalmersBob, Thanks for the heads-up on the drawbar. I was thinking of using it on occasion for pulling a small trailer, and will not only check the mount, but rethink the limits of use. AC put the drawbar there for a reason, probably with factory limits spelled out in the owner's manual. If this works out, I'll see about getting the books that every owner should have.
 
many of the engine internals are compatible with a massey harris pony.. though it is a different block casting, especially when you get to the starter area.

IOW, both ~12hp Continental engines? You mean used parts, or still available new? Which make has the best parts support?

I'd hate to scavenge a Pony with good engine parts to keep a G going. I think if the G engine was that bad, I'd come up with something different. Just saw one on E-bay (in California) that was converted to electric - 8 6v AGM batteries for 48v to what is probably a forklift motor. I heard years ago that some comedy guy on TV wanted to fit a Harley V-twin to a weed whacker. Might be more fitting on a G, but then I'd have to replace the steering wheel with 'ape hanger' bars. Hmm...
 
The big end of the rod is wider than the diameter of the piston.

many internals are still made for the g and pony.

plenty of surplus parts too.

I know a guy that converted G's to isuzu diesels. ..
 
Rear axles that have been broken, then welded, not turned back true resulting in leaky seals is an all too common of problem. Of course, leaky rear axle seals problems lead to brake problems. If it doesn't come with the tool bar and lift mechanism, they can be pretty hard to find. The front axle is pretty delicate and subject to wear - no grease fittings and few if any bushings! Steering gear is a suspect too. Then too, as with all oldies, the carburetor and governor can present issues. Exhaust manifolds seem to be vulnerable to rust too. But, just think of all the satisfaction you can glean from solving/fixing all these problems!
 
Thanks, Dick. Now it makes sense with being such a small CID. It's gotta have a great low end pull with 4 cyl vs the same HP with 2, or even 1.
 
Leon, one of my favorite things to do is fabricate and fix stuff. Missing tool bars would be simple to make. Axle fixes may be a bit harder, but still doable, depending on spline condition. Are busted axles common? Is there a new replacement available?

Have to put off the trip to go see until next weekend because the better half brought home a bug from her time at the farmers' market last weekend and kindly shared it with me.
 
All other things being equal, the number of cylinders has nothing to do with pull.
 
You don't need a ring compressor, there is a 45deg cut at the bottom of the cylinder, you just push the piston/rod assembly in.
 
Thanks for the info, WBecker.

Charles, Oklahoma is a bit too far for me to go to get one. It might be nice, but I don't need it THAT bad. :)

Trip put off (again) because of Lake Effect Snow, and playing catch-up on things needing done before the snow flies... yup, a little behind.
