It's stuck, no more guessing

I found the problem with my A/C Model M. After a 4 ft pipe wrench, and a 8 ft cheater I decided it's stuck. It wasn't too many years ago I could lift the head by my self. I tried to carry it to the shop from the back of my pickup, and dropped it in the dirt. What happened was the gasket corroded, allowing water to seep into the cylinder. Always something to do. Stan

I sure admire you ambition , in these parts a crawler that old quits running it is parted of junked. Just no many folks spending the time and money to fix 50 year old equipment.
 
If I didn't have a few parts tractors it would not be worth fixing. I had the gaskets, all I needed was a ring set. Stan
 
I don't think the M had high production numbers and I have only seen a couple. Vista tractor museum has one in good shape but does not look near as nice as that one. If everything that was old was junked not many of us would still be here! Not often do you see a crawler with straight sheet metal like that one. Crawlers seem to get all the chain duties and you know how that will go. looks like a farmall regular or f model hiding under a tarp. Like the old saying, if you want a running tractor, run it! best of luck.
 

Then it is time to fill em up, Cover it and let it set till early spring..

Cant be too many AC "M" models left are there?
 
I have a mostly redone 1928 Cat Twenty thats been in the family since late forties and I expect to see it turn 100! I am hopeing I
don't make it that long...........
 
Stan are you the fellow out west that uses the crawler to disk some of the neighbors ground ? Someone has posted some photos several years ago .
 
I still use the M's in my mowing and disking business out here in southern Calif. Going to be busy in a few months because of all the rain. I have a JD and a MF for mowing.Stan
 
Another very nice looking M! Is the blade factory, aftermarket or home made? looks awesome. Bunch of other AC"s in the background,
must mean your hard core AC guy!?!
 
Out here in socal I see F20 and F30 and not f12. After 26 years you think its stuck too? When i see air cleaner oil cups with that much oil on the outside usually means it has only water on the inside. I have 11+ tractors and all the support equipment, welders, sand blaster, air compressors and with the garbage gas, I can only keep a couple of them running. They made the M for three years, was there any other AC equipment the M engine was used. The M at the museum has a wd starter with the lock hole drilled in a different spot and has since been lost................chuck.

Actually over 14,500 were made from 1932 thru 1942. They are pretty common around here....lots of them just rusting away in the trees.

The story I was told is there was a fab shop in Pullman, WA that made this dozer blade setup. Yes I have close to 100 Allis tractors hiding around here. this pic was taken close to 10 years ago.
 

An old-timer friend here has an odd one ( I think)..it is AC, but it is built like a giant AIR COMPRESSOR..!!

The engine front of the engine block looks just like a WD engine..BUT..there are 2 MORE cylinders cast in that same casting to the rear of the engine block..Compressor Cylinders..

It looks real good he keeps them all inside and this one he will sell...
 
I think they were more common on the west coast. All my Dad used for ground preparation when he farmed was the M. His were set up for Butaine. When I started doing disking I started out using propaine. It was just too much of a problem. All I use is gasoline now. I Around 15 years ago I would see them for sale, none any anymore. I have a few my self. Most have a lot of hours. I have a Orchard model with not too many hours. I found it where I was mowing a few years ago. I'm changing the anti freeze, to keep the gasket from corroding and leaking into the cylinder, before I have another problem. Stan

I think that would be a LeRoi Tractair
 
Mine is a military model but it is orange and a cable lift blade where do you get gaskets for them, I am back east in Ohio and it is very hard to find any parts for them that is why mine has set for over 15 years and I need to get back on it before I am not able to work on it thanks for any help

Cheif,
Years ago I took the head off a 4 cylinder engine that looked like yours. It sat under roof for many years. No way rain got in. I concluded it was condensation caused by temperature changes and humidity getting in via an open valves.
