Super A -1overhaul trouble

[T.R. Dickinson]

Hi I'm restoring a 1954 Farmall Super A-1. I ordered a rebuild kit and I just went to put the new sleeves in and they didnt fit. I measure the sleeves with a mic there is a .115 difference in the diameter of the sleeves. What should i do?

Did you put the sleeves in the freezer before you tried installing them?

 

[nosih]

depending on the block, there is a difference in the lower sealing land diameter.

There are two engines that can be in an A one has a small block bore the other one ~1/8" bigger. They are just the wrong parts. Either order the correct ones from this site (good option) and get your bucks back from the original seller. If yours are smaller, your block has probably been replaced, Jim

You should have measured your old ones as most suppliers will ask what the measurement is at the bottom.

The block has c123 cast into it. Its a A&I products kits.

let please keep the comments constructive.

Gene may have been a little brusque, but he was being constructive. Whoever you got the parts from should have asked you the lower diameter of the sleeves, the serial number, the block part number, or even if it had C-123 cast into the side. Any of those bits of information should have gotten you to the right parts. From what you have said, I assume your new sleeves are 1/8 inch too small at the bottom. All listings I have seen for Super A S&P sets have listed the serial number break. Look at the Super A engine parts listed on this site (Marketplace in upper left) and you will find multiple sets listed along with enough description to pick out an appropriate set.

The change in the blocks was made to allow larger displacement with thin sleeves, or 123 if used in that tractor. The other block was 113cid or with thin sleeves 123cid. The seller should not assume anything, but they did. It is a common issue unless experience has taught the difference. Sellers often just don't know enough about what they sell. Jim

 

[Janicholson]

Bingo. Jim

 

[T.R. Dickinson]

Their .115 too big on the bottom.

 

[El Toro]

If you have block casting number 354898R1. Your sleeves should measure 7-1/32" in length and and at the seal 3-7/16" in diameter. Hal

 

[El Toro]

The sleeve kit you have would have fit the Farmall A and the early Super A's. They had the C113 cid engines.Hal

When i call for replacements they will ask what the measurement is at the bottom you must have got someone who wasnt up on the sleeves that are available. When working on old tractors dont assume anything you never know what has been done to them prior.

(quoted from post at 20:53:16 09/07/13) Their .115 too big on the bottom.

ou are saying the sleeves are too big? I don't understand that. Everything you have said indicates you should need the large ones. What is the actual measurement of both an old and a new sleeve, at the bottom where the o-ring seal rests?

Gene is giving it to you straight. You should appreciate his knowledge and expertise. He correctly sized up the problem and succinctly gave a direct, unambiguous answer. It is likely the most constructive answer given in this entire thread.

Gene (and others on here) have repeatedly advised novice C-113 & C-123 engine rebuilders to pull a sleeve and measure the diameter of the old sleeves before ordering parts. It is, was and will continue to be sound advice. The question above amply illustrates why.

Correct answers should not have to be wrapped up in padding and soft words.

 

[El Toro]

The early Super A's used sleeves that measured
6-7/8" in length and the overall diameter at the sleeve seal was 3-5/16". Hal

 

[CNKS]

They are wet sleeves, not dry, and go in easily provided they are the correct sleeves.

As stated by T.R. Dickinson, the block has a 123 cast code identification. This particular block was used in latter years on IH models such as the 100's, 130's, 200's, 230's and 140's. I have all of these models and there were several changes in the sleeve design through the many years of production of the 123 cubic inch engine. I have never seen a 1954 SA-1, SA-I or a SA-1 High Crop with 123 cast code stamped on the engine. This showed up on the engines starting in 1955.

My advice as others have stated, measure before buying.
