Super A piston/sleeve options?

CenTex Farmall · Feb 21, 2015

We have started on a Super A that Dad bought a while back. It was stuck and we have it all apart for rebuilding.

In the last rebuild it got 3 1/8 firecraters so it was already made into a 123. Bearings were dated '65. I'm not familiar with these and am wondering how the blocks changed over the years. The serial tag is missing, however the block was cast on 8-15-T, 1950 IIRC.

Will sleeves from a C or Super C fit this block? The block bore is 3.6 at the top and 3.312 at the bottom. The top flange is 3.842 and the step is .225 deep. These may be +/- a few thou as I was using my "field" calipers.

You can get Red Power sleeves and pistons hi-dome for that engine. Just make sure they have the bottom measurements for your block as thetops are the same.

YT has piston/sleeve kits for your Super A, they are offered in both flat top and stepped head pistons.

Super A and C sleeves are the same, Super C sleeves are larger in diameter and will not work in a Super A.

Measurement needs to taken at the bottom as the top is the same. The 3 1/4 are larger at the bottom where the o-ring seats. Thats why you need the measurements before ordering. The 3 1/8 can also have larger dia at the bottom. Depends on the block.
