I suspect there was wear in the bearings of the boring machine used, the deeper the bore the more pronounced the deviation would become, I really hope they didn`t use the same machine to do the bores for the new liners. The finish on the bores is terrible suggesting the machine was in poor condition.

It certainly sounds like a challenge.

Bruce, there are several proper ways to bore a cylinder and a few more ways that shouldn't be tried. Not sure how tvis was done. Hopefully the bores in the blocks aren't tapered also because that is very hard to correct when I'll only be taking out about .030"

The 0.010 inches larger at the bottom cylinder bore has me scratching my head.  Perhaps a novice changed a dull cutter and forgot to adjust for it???

I'm rebuilding a Lister ST1 and need general specs such as torques, clearances, etc.  I would also like to obtain a parts book

Bob, I share that worry and plan to check the press fit. Luckily he used 1/8 wall sleeves and 5/32 are readily available thus I can repair if they are loose. The OEM piston inventory is all used up to my knowledge so India is the supply. Currently available is .5mm and 1mm oversized. It sure is easier to repair a worn engine than follow a bodger tgats for sure.

My biggest worry about this is that the person that bored the cylinders, after sleeving, may be the same guy that fitted the sleeves. Is there any reason to believe that the sleeves are a tight fit and will not have hot spots or even be loose? I think it would be safer to start again from scratch. For what it`s worth, Lister used to make oversized pistons in 10 thou increments up to +40 thou, but you already know this so I`m trying to teach my mother to suck eggs.
I suspect you know how to shrink a seized bearing by running a bead of weld on the inside. I have never tried it on a cylinder liner but in theory it should work just the same, might be worth a shot if they have fitted the largest liners available.

Bob, The plan, if I can get the parts is to bring the dry sleeves out to .5mm or .020" over. If pistons arr not available the only choice will be to remove the sleeves and start over.
