I'm working on trying to fix a Farmall Cub that froze last winter.

 

http://gardentractor...e-5#entry479966

 

The coolant that I put in it wasn't good enough, the top of the head is cracked and the front bolster is cracked (part that the rad, steering box and front axle mount to).

I can't see any other cracks or spots where water/coolant is leaking out.

The engine runs good, the oil looks good, the level is at the full mark, doesn't appear to be rising. ???

 

Question  Where do these tractors crack when they freeze? Where should I be looking?

Could you put a pressure test on the system to help see any other leaks, just a thought.   Noel

Today I was able to get the parts needed for it, used parts found locally, hopefully they work out.

Update

Today I got this thing running again.

Replaced the cylinder head with another good used one that wasn't cracked, had to clean out the carb to get it going and all seems good. No leaks from the engine anywhere and the oil level stays the same, no sign of any water getting in there. It runs as good as it did before.  

 I let it run 2hrs, checking, then shut it off, let it cool down and re torque the head again. 

 

The front bolster has a nice long crack in it which leaks, I bought another used one that has been repaired, all I could find at the time, but the one on the tractor looks better even with the crack in it. So I drained the water, drilled the crack at both ends, cleaned off all the paint and rust, opened up the crack with a narrow cutting disc on the angle grinder, and cleaned out the crack best I could.

Mixed up some JB Weld which I pushed into the crack everywhere. 15hrs drying time they recommend .

Tomorrow will see if it holds.

Gad zukes!! A good torch and silver solder with a good flux would have fixed that.. Dont have much use for jb in my world.

Picture of the JB weld repair, if you look close you can see where the crack was.

I filled the rad up with water and so far no leaks.    

Will see if it holds as time goes on, going to run it, heat it up then let it cool off a few times over the next day or 2.

I hope this does it this tractor wants garden work and the growing season is almost here.

So far so good, no leaks, I put the gas tank back on greased the tractor and all seems to be good.

Rain in the sky's for tonight, hopefully tomorrow I can grind the JBweld down smooth, put some paint on it and deliver the tractor back to it's owner so he can use it.

OH    1 thing and very important, drain the water out and put in some GOOD ANTI FREEZE.

That's a very big crack.

With as many of those as are out there, you would think that someone would have made a sump that sits in the bolster to fix this design flaw. It could even bolt in with the same flange and some kind of rubber hose thru the original water line.

They make that bolster, aftermarket ones that can be bought new as replacement's, about $400. US I think. ???

[MH81]

I meant a sump that goes in the bolster.
400 is a lot of cash. At least someone makes the part so it doesn't have to be scrapped

Finished

Today I'm going to put a big smile on my friends face.

Was over at my buddy's place today and used the Farmall cub in his garden cultivating, works pretty good and no sigh of any coolant leak, so far the JB Weld has held up good.
