cylinder sleeve removal

[whodat526]

I have heard that welding a heavy bead around the inside of the sleeve can loosen it up (as the weld cools it contracts and makes the sleeve a hair bit smaller and easier to extract)

this is how i always remove them

Hello Everyone again,
I have successfully removed the cylinder sleeves from my 1958 ford model 641 134ci gas engine. Whopee It took all day Wednesday just to get the first one out, you cannot pull from the top by welding a "ear" to the thicker ledge of the sleeve because as soon as you put pressure on the homemade puller the sleeve will just break off. I did get the sleeve up far enough to drill a 3/8" hole all the way through both sides and insert a rod through and fabfricate a "jig" to pull some while I beat upwards on it from under the tractor. I ran out of space with my puller and drilled another hole lower in the sleeve and repeated the process,Whew what a process!!
After the sleeve was out of the engine I then fabricated a puller to pull from the base like the tools made to do the same job with the exception being that I do not have a metal turning lathe or access to one so I carefully cut a 1/2" x 1-1/2" iron stock to just fit the inside diameter of the sleeve then cut another 1/4"x1-1/2" to the outside diameter,drilled and bolted them together with slack in the bolt holes to adjust and hand file until it fit just right then welded them together and welded a 3/4" heavy nut to the top center. OK, never mind that because it did'n work anyhow!! The 1/4" metal is too thin and bent and broke away from the 1/2" inside piece!! I did the process again using 1/2" for the outside diameter piece and that worked great.
I turned my welder down to low and used ac rather than dc current and ran four equal spaced small beads vertically inside the sleeves, positioned the puller and yanked them right out. The last two, when I finished welding the beads I wiped the inside of the sleeves with a wet rag while the block was still warm and they slid out without any chatter at all.
I have some pictures on my phone if I can figure out how to attach them this would be better than this post.

Just thinking, I bet if you could hook up the puller just right, then take a co2 fire extinguisher and give it a good shot down the sleeve I bet it would even work better, who knows, you may not even have to rund the weld??
When I was in the service we used to cool out "beverage" by putting them in a paper bag and hit it with a co2 extinguisher and presto it was cold.
Bye for now,

If you know any HVAC guys you could get some Freon, It works for me.
