Other ways to remove a wet sleeve?

[paulinkansas]

I'm replacing the pistons, rings and sleeves on my A/C D17, but can not get the wet sleeves out. I've tried pounding them up from the bottom (crank is still in the block, block is in the frame), and tried building a sleeve puller from some 3/8" flat stock and all-thread. The sleeve puller just gets bent out of shape.

Anyone have some other suggestions? I thought about heating it up slowly with a torch to about 300 degrees, then applying some ice or water to the sleeve. I also thought about cutting a slit or two down from the top with an angle grinder and cut-off wheel to weaken it a bit before attempting to pull or pound it out.

Lay 2-3 beads around the inside of the sleeve with a welder? (if you can ground to the sleeve, perhaps tack a bolt on first to use as a grounding point)
That should shrink the sleeve and cause it to pull away from the block.

The last ones I removed took nearly the full force of my 20T press....it
was a 4-cyl m/c engine.

I like the idea of heating by arc welding. It will be hard to get the
kind of force you need with the crank in the way, however. Maybe
you can use a jack under the tractor, supporting all the weight on
one sleeve at a time, then weld, then use an air hammer from the
top to vibrate it. Don't distort the lower part of the sleeve. Good luck.

Pack them with dry ice, heat will expand the metal cold will contract it.

Guys:


They are wet sleeves, should be an O ring holding them in. I've only taken out the sleeves with the crank out. Large block of wood and large hammer. They are much easier than dry sleeves! Here is a pick from a C-135 engine, on these the cylinder lip protudes beneath the block so you can whack it hard to get it going. Once it rocks, it comes right out. It would be hard to do from in the tractor without a real puller though...

Aaron Z Has the easiest method, That is also how you remove an outer bearing race from a blind hole. Works perfectly . Run a bead of weld around the inside it will pull it away from the cast block when it cools. KennyV
PS ... keep weld spatter off your crank .

This sounds like the same set up we've used on 504 Case engines but was made from 3/4 or 1" thick material and 1" all-thread. Never had any problems getting them out.
