Sleeve slides out of H block

farmallfarmer · Jul 12, 2009

I'm in the middle of a complete engine overhaul on my '52 Farmall H, I put in all new sleeves and pistons and everything was working fine until I turned the crankshaft around to put on the last two connecting rod caps, and the #3 sleeve pushed up about halfway out of the block. I can push the sleeve back down in easily enough, but if I turn the crank around again the sleeve comes right back out.
I've been told before that painting the outside of the sleeve with aluminum paint and sliding the sleeve back in and letting it sit over night will seal the sleeve up good,and keep it from sliding out again, but I wanted to make sure before I painted one of my sleeves that this was a good idea.

If this is a bad idea then I'd like other suggestions about how to keep the stubborn sleeve down in the block.

Thanks

Clean everything REAL good!!! Then loc-tite it in. Locktite red or sleeve retainer compound are your best bet. That is what I have used in the past.

myself i use nothing because you want good heat transfer to the block. i just hold the stubborn ones down when turning the engine over.

The correct way is to (I realize the issue) buy a sleeve designed for the hole tolerance.
Some have used Iodine as a paint to literally rust the sleeve into the bore.
If I were to make do, that is what I would do. It would be very rough on the next rebuild.
Doing nothing will not be a good idea. The heat transfer is poor and the sleeve can crack at the top and be pulled down into the rods. Way uncool.
If you send your sleeve to LA Sleeve, they will make a new one larger. Tell them the actual bore of the hole. IH made them in select fit sizes. Marked with letters on the block deck. near the cylinder. ABCD D was the largest. Kits tend to use only B size sleeves, but if one went in tough, that sleeve might do wonders in the big hole. JimN

You won't get the best heat transfer with clearance, and there has to be clearence for the sleeve to move up and down.

I had a loose sleeve on my 8N at one point. I shrank the sleeve down with LN2, wrapped on just enough aluminum foil to produce just the right interference fit, and pushed the sleeve down. Held until I rebuilt the engine several years later.

i cant see how loctite transfers heat. i know they arnt supposed to be loose in the bore. but if i put them in with a hard push then i leave them alone.
