I am looking at a $500 running Allis model b with electric start, pto and 3-point hitch that has a horizontal crack on the left side of the block near the carb.Coolant leaks from the crack but doesn"t get into the oil.The current owner has run it like this for a few years grading his driveway with a drag blade.He said "The motor doesn"t create enough HP to over heat".Don"t know if I agree with him and would like some advice on how best to repair the motor.
Drilling holes at the ends of the crack, heat with a Oxy-Acetylene Torch, arc weld and grind.
Could the repair be done with the motor still in the tractor or will it need to be a bare block?
Also being driven around low on coolant probably caused cracks between the sleeves and perhaps the head.What could one expect, price wise, when looking for spare parts.

The JB Weld old suggested should work. I would grind a V in it like he said. Drain all of the coolant. Then take use a torch to heat it up enough to get rid of any coolant that is trying to seep out of the crack. A hand held propane torch should give enough heat. Let it cool of and wire brush it good. Then follow the directions on the package and you should come out okay.

The head is probly alright. The heads on these engines are really tuff. If it was bad you would have water in the oil.

Without water they will over heat as in any water cooled engine. Running hot will cause cracks between the sleeves. The crack can be fixed with the engine still on the tractor. If you just want to stop the leak and do not care how it looks you can put a steel plate patch. Welding to be successful you would have to remove the engine and take to a shop that could place the block in an oven or some way to slow cool it. Stitching is another good way to fix it in. Takes a bit of time and a lot of drilling and taping. You drill a hole at one end of the crack with a special tapered drill and tap the hole with a special tap. The next hole is started and drilled at the edge of the plug just installed. This is continued the distance of the crack.

Dick L Thanks!
I will probably just weld a patch to get by until winter and a suitable parts donor can be found.

The patch I was talking about you drill and tap holes and place gasket material under the plate over the crack. If you want quick and dirty just clean the area of all dirt and oil witha wire wheel and spread a bout a 1/4inch of bondo ofer the crack. I have not use it myself except for a car I bought in the 1960's that it had been done to it. I drove it several years and it never did leak. The bondo would be the easiest to remove later if you wanted it to look better.

If you need a block I have 2 spare ones. These are out of Cs but there the same engine any how. I have 2 Cs that are just parts. E-mail is open. I've junk out/parted out more then one tractor because of a crack like that

I'm in Missouri, the lake of the ozarks area. I think a stripped down block weights less the the 150lbs max for UPS but I'm not 100% sure. Other ways you can fix that is grind a V into the crack and clean it real good and then use JB weld on it. I have seen a good many blocks with JB weld in a crack like that

Old,
If you part out a tractor with such a defect would you recommend against buying this one?

Does the blade come with it?? If it does then at $500 your probably not getting hurt but I would try to get it for a little less say around $400. You might be able to JB weld it and have a good tractor for years or it might crack worse and then you would need to at least replace the block. And if you do have to replace the block you could end up spending around $1000 to fix it right but even if you did have to spend that on it you would still have a tractor thats worth around what you would have in it

Thank to everyone for their advice.
Since my need is for a tractor to work with now and work on later I spent more money and bought a 1975 MF-135 with a perkins diesel.It runs great and came with a brush hog for $2600.Needs paint but paint is cheap and doesn't affect operation like a cracked block will
