Hello everyone. Glad to be your newest member. I recently acquired a 1949 Farmall Cub. The sheet metal looks very straight and the tractor is all there. Even the decals are readable but the engine is seized up. After soaking 3-days with 50/50 mix of turpentine and diesel it won't break free, so I finally pulled the head and the last cylinder is full of corrosion, cruded up like a carbon buildup. looks like he used plenty of anti-freeze. Anyway, I don't think the engine C60(?) will clean up with a .060" overbore. Front 3-cylinders look great but last one next to the operator is so caked up on the cylinder walls I suspect I would need a sleeve. Earlier today a man was telling me people have used sleeves for a Kohler Engine to restore the block on a Farmall Cub. I just don't know which Kohler engine sleeve to ask for. And, I don't knw if it'll be long enough to cover the entire length of the cub cylinder. Does anyone on here know of a sleeve or heard of sleeving a cub with a Kohler engine sleeve?

Welcome to the best forum on the Web. Sleeving was discussed not too long ago, see the below link to the topic. The general consensus was that, because the engine was not designed for sleeves, it is more cost effective to get a used block or good used shortblock. However, a few members have had success with sleeving blocks.http://www.farmallcub.com/phpBB2/viewtopic.php?f=1&t=83385

It probably isn't cost effective if you have to sleeve all 4 cylinders. A case like this, where there is 1 damaged cylinder, it can be an effective fix for a reasonable price. Find a local automotive machine shop that can bore the block. Have them evaluate it and let them find you a sleeve. They have regular sources for such things. I can't tell you if a Kohler sleeve is a possibility or not. The machine shop should be able to fix you up in any case.

As far as I know the machine shop I use can get repair sleves for any non sleved engine. Had a C-60 sleved to repair hard water damage last year. I had a 04 jeep 4 cylinder sleved do to shattered piston damage last year.. In the case of the jeep engine a block was 800 bucks. sleve and machineshop work was 150 bucks. In the case of sleveing a C- 60 with one bad cylinder I would think it is cost effective when it cost 100 bucks to sleeve one hole. all depends

I recommend cleaning the cylinder up first for a good look first. Is the engine still stuck? It might help to add some penetrant solution to the bores, let it soak for a few days. Remove the starter and use a bar like a tire iron or large screwdriver to try to rotate the crank. When freed, position each piston at the bottom and clean. A cylinder hone will not remove enough metal to make a difference and you can evaluate what's usable. If the crank will not turn, you will have to remove the pistons to get it free. It can be done, I just finished one like that.
