Welcome to my Nightmare!!!!

Eddie, once again, I must say, "You are the Man"

I consider myself a fair mechanic, but you jump in both feet and make it happen. My hat is off to you, looks like you are doing a great job, and I would also fully agree, that once I was in that far, I would want to only do it once and be done with it. I have to believe that what you are saving in labor more then makes up for the additional cost in parts.

Anyway, as to freezing things, when a main rotor head gets stuck on a mast (similar to what you are dealing with) we will build a little dam down inside the mast (hollow tube on an apache) and then fill it with dry ice and it will contract enough to make the head bearings come loose.

I think you could do much the same thing with your new liners.

I did love the thought of returning the freezer to Lowes though /forums/images/graemlins/grin.gif But even more so I can see you walking in with the sleeve, and Test fitting all the freezers /forums/images/graemlins/grin.gif

Might be time for a large ice chest and some dry ice.

That sounds about right for cooling the sleeves.

For heating engines, I have used a few (6-8) charcoal briquettes in an old pot on the ground under the block. The pot handle is convenient to move it around. Don't use an aluminum pot, it won't take the heat.

After the lighter fluid has burned off, this is a pretty clean source of heat.

I would remove the heat before working on the block, due to CO and CO2.

What seals the joint betweeen the block and the sleeve?

If there is any rust, scale or other corruption in the sealing area between the sleeve and the sealing surface in the block will there be trouble?

Does anyone with experience care to comment?

Dave

P.S. I want to see a picture of this thing working after all this... )

Dave,

The attached picture should help with understanding how the sleever works. Basiclly it is the cylinder wall for the pistons. It is completley surrounded by water, thus it's a "wet" sleeve.

The bottom of the sleeve sits of four prongs. I drew a red circle around one of these.

The middle of the sleeve is a perfect fit into the round ring you see in the picture. This is a machined surface that is the bottom of the stroke for the piston.

You can see above this ring the water cavity inside the block. This is the aread around the combustion chamber.

The top of the sleever has two levels. One is flat with the deck of the block. Then the inside portion of the sleeve is taller and slides into the cylinder head.

These two heights combined with the head gasketp and 148 lbs of torque on the head bolts holds it all together.

From what I can tell, there is absolutely no rust or pitting of any kind inside the block or on the sleeves. I've always had lots of anti freeze and will put 6 gallons in when I refill it.

Eddie

PS. When I get it runny, I will post plenty of pictures of it in operation. I have way too many projects for it to accomlish!!!

I have heard guys talk about soaking liners in ice water to shrink. Also they talked about giving them plenty of time in the soak. They said if you get in a hurry and try to put them in too soon they will get part way in and have to be driven in with a block and sledge hammer. Also if you add plenty of salt to the ice and water you will get a colder mix.

I would be leery of immersing the sleeves in cold salt water. That sounds very corrosion to me. Possible future problems with the sleeve/block interface.

I like the dry ice idea, myself. Colder and non-corrosive. Just my opinion.

Eddie:

Thanks for the reply.

I think I understand how this works.

Here are the areas I am wondering about Picture .

I am hoping that the deposits I see are either not scale or are not in the sealing area.

Dave

P.S. Anyone have any idea how I attach a picture with a Mac. Every time I try, it hangs up. I seem to be able to store them online and then put in the URL as a work around.
