I need to install a sleeve in a AD3-152 engine. I have heard to use dry ice and acetone. How long do I leave the sleeve in the ice. Dick
 
I believe it is just temporary, you insert it in few minutes, say 10 or 15, let it shrink on down. The instant you remove it, it starts to expand, so you have the dry ice immediately beside the engine block. Then hustle your bustle, get that sleeve in quick before it starts to expand. Immediately, I believe.
 
Same trick works for wheel bearings and the like. I put my wheel bearings in the freezer overnight and I hardly have to press them in at all. It works best if the location of the engine you're working on is warm.
 
I put the sleeves in the freezer and placed a red heat lamp on the block for several hours. The sleeves installed easily. They're very thin so use a wood block and carefully tap them in with a hammer.

Same with me, if your freezer goes down to 10 or 15F, and you put a light bulb on the block if it is cool out, the sleeve should slip in without a fight. Just walk out of the house fast, straight in the block. A few taps with a mallet, should do it. You don't get burnt, you don't spend $$$
 
Those dry sleeves engine could also in theory be fulled with hot water and then you pressed cold shrinked sleeved in ther, right?

few years ago, I could not remove sleeve from a MH55 (threads pulling off a 3/4 screw), I put ice cubes in the sleeve, wait 2 min, got them off quite easy... Ice works and is cheap.

You would need some block off plates, and be able to circulate the hot water. Easier to heat the block with a heater of some sort, or a oven. We have a refrigerator/freezer in the shop, and let the sleeves sit in the freezer for about a day.
