Book says .002-.004.Center two seem about flush.How important? What happens if they aren't high enough.You can "feel" the two on the ends but not #2&3. I really NEED measuring tools!LOL

You can "feel" all of them by laying a .002 feeler gauge on the deck. That should be flush with the top of the sleeve. I don't know how critical it is but that is what seals the cylinders and keeps your compression in.

Its better for them to be flush with the deck. I run all mine flush with the deck and the fel-pro blue head gasket had no issues with water oil or compression staying in the areas they suppose to . cylinder pressure at cranking speed and four pumps pegged the 350 lbs compression gauge . Never lost a head gasket never had promblems . run a copper custom gasket now because of the bore size sleeves are flush with a stainles wire oring to cut into the copper headgasket compression ratio is 15.3.1 water is where it should be oil is also and compression stays in the bore also. Alot of 226 pullers have water and oil issues I guess me doing everything wrong makes me lucky.

More about how is the deck of block front to rear frist ! I like to see sleeves up .oo2 - .oo4 .My shop charges $125.oo to deck block and cut conter bores.Each sleve can check OK .BUT is the BLOCK FLAT front to rear on DECK. With all sleeves in put a long straight straight on them see how they are to each other.

I do not mess around with tractor pulling and I still do this,its cheap and makes a dam good JOB with COMPLETE over haul. My 3 cents

I agree 100% with Fred. You could have everything "measured", bolt it together and still have problems. If the head and the deck aren't flat to begin with you got nothing.

This is the detail as to how I do a sleeve installation .Sleeves go in the decked true block .Material usually aluminum the same thickness as the head gasket I plan to use goes on the block . A spare head that I have thats decked goes on top and is torqued sets over night torque gets rechecked in morning before head comes off. If sleeves have droped then the block and all sleeves are decked until flush. I then repeat the above step untill all sleeves stay put and flush. I have had to chase press interference sleeves as many as 3 times before . the oring sleeves usually dont require as much . line hone the thing and throw the file you planed to use to fit the bearings in the welding booth to clean welds .Must 1950 blocks the mains have sunk in them and they need lign bored anyway.

fixing bent rods from water leaks isnt simple. attention to details is everything sometimes pay me now or pay me latter is the frase when detail doesnt get the deserved attention.

I like to have the sleeve .002 above the block deck as well. However on my C that I built the engine up with the D sleeves to seal the bottom I used expandable cement and as it set up the sleeves moved slightly so I had it decked flush. Even with the high compression caused from the pistons entering the firing chamber with .200 off the head the standard head gasket held. I assume that Allis Chalmers was planing for less tolerance between the head and block for production reasons when they called for the sleeves to be above the deck by .002 -.004. If a person is not going to resurface both the head and block I sure see the need for the sleeves to be that high.

I guess that's the difference between the Buda diesels and genuine A-C engines. ML's compression is about the same as the Buda diesel. Everyone I have talked to says absolutely +.002 on them. The original blue prints say flush + or - .002.

Now that I think about it, I don't know if I ever checked the sleeve height when I overhauled my CA about 14 years ago. I just remember having to run my hone in the lower end of the block so the sleeves would set in like they should. They did fit tight to where I had to hammer on a sawed off piece of hedge fence post to get them down all the way. Hasn't been messed with since. I did have to have it line bored. Just like ML says, the center bore had dropped.
