Case 500 engine removal

Just bought an old 500 diesel with a big hole in the side of the engine block (freeze damage), though I would have a go at welding it. I assuming its going to be easier to weld if lying on its side so just wondering if there are any particular issues with the removal and re-fitting of these engines. Looks as if its should take too long or be too problemantic to take out and refit but any thoughts welcome. Welding of course will be an entirely different matter. Should it turn bad is the 900b engine block the same as the 500?
Thanks

Bill, have you ever welded cast iron before? If not remember the words engraved above the gate to the underworld: "Abandon Hope, All Ye Who Enter Here". If you just walk up to it with a 6013 rod in your stinger and buzz away, you'll look at a nice pretty bead, chip off the slag, and watch it crack all the way down one side of that nice new bead. If you have another block lined up that would be ideal, if not leave cast iron welding to an expert. Not your next door neighbor with his brand-new MIG, a certified expert. As far as getting the block out of the tractor, get and read the manual before you decide to tackle it. You'll need most of a barn for most of a year.
 


Bill,
I do a fair amount of cast welding mostly acet/ox with
oven to pre and post heat ( required). With any kind of welding
the base material needs to be hot enough to get all the
expansion out. Cast is not ductile. Preheat to get all the
expansion out is 900 to 1000 degrees F .

Highly recommend lacing it with lock & stitch plugs , better
than iron tite for the application .

Well, it wasn't a motor block, it was a Dutch oven, and it was against my advice, but I saw it done. If I ever need some cast welded, I'll look for George, even though I'm OK with a stick or torch. OK enough to know when I'm over my head.
