172 ford cylinder

Keith-OR · Oct 2, 2022

Any idea where to get one sleeve 40 over bore. I have one cylinder that has an un-usual ware in the sleeve. This site does not have any, just 4 inch sleeves..

Thanks

How tight is the press fit? The only solutions that I can think of is run on cylinder at std size or if the sleeve press fit is tight enough you could have it bored and honed after installing it.

The engine has been bored 40 over, just one cylinder seem to be wore un-usual. They have over size piston on this website but no sleeves.
It is not that bad where it can't be used, I would just like to replace it since I already have the head off. And I have a sleeve puller, so it would be no problem.

Thanks

Theres a reputable firm in Midlands uk that specialises in making liners/sleeves

I think I may have missed something here. Let s start over.

Is your engine a sleeved or non-sleeved block? As I understand they were made both ways.

It sounds like yours is non-sleeved, but I could be wrong.

You could have your block sleeved, either with a repair sleeve or setup for the standard sleeve that s available. Both 3.9 and 4 overbore sleeves are available. 3.9 are listed for gas and diesel.
You could have the new sleeve bored for your .040" pistons if you insist.

Depends on how much $$$ you want to spend.

Mine is a 172 sleeved engine. would like to find a sleeve to replace the bad one, motor is still in the tractor. All I plan on doing is ,drop the oil pan, remove piston, and pull sleeve and then install the new sleeve.

I think you are looking for a needle in a haystack. If I wasn't going to do the whole engine right, I would buy a standard cylinder kit and put in that one hole. I could never figure out why anyone would bore a sleeved engine. By the time you pay someone to bore it and buy oversize pistons and rings you can buy standard cylinder kits and put it back to standard. We just finished one last week. An old Ford Mechanic told me many years ago, Don't waste your time and money trying to re ring one of these engines. I didn't listen and he was right. We could never get the rings to seat in the old sleeves. Drank Oil from day one. Ended up doing a complete rebuild. Good Luck

Buy a standard sleeve and piston the engine will never know. I had
a TW10 that the air filter indicator failed and let dirt into #6 cylinder bored that hole .060 and used the tractor another 5000 hours ran as good as ever.

This engine has been recently rebuild, and never ran, has new pistons ,sleeves. Only thing I can determine is that got water in #2 cylinder. Why would I put all new pistons, rings and sleeves, when all I need is one sleeve .040 over bore. I might take one of my old sleeves from a rebuilt 5 years ago, chuck it in my lathe, and see if I can bore it to 0.040. I can't hurt a thing, OLD sleeve.

My philosophy, if you're going to do something, do it right or don't do it at all!!!

Thanks,
Keith

If you are going to bore a sleeve, it needs to be bored after it is inserted into the cylinder. Boring it first and then inserting it will most likely result in it being out of round, at least by a small amount. Doing it the way that you propose violates your stated philosophy.

I'm going to talk to a machinist friend and see what he thinks. He has a machine shop here for 40+ years. I think if ya don't get in a hurry and just take extremely small cuts at a time, it can probably be done. I have 4 old sleeves that I can practice on. also have all the inside gauges and mics to check for out of round. And I am going to make a gig (heavy wall tubing) to put the sleeve in, to chuck it into my lathe
I had already thought about it being out of round without any support for the sleeve.

Thanks

It might be perfect after being machined on your lathe, but the act of inserting it, if it is a tight fit as it should be, can cause it to become out of round.

I have done this before, make a tight fitting plug out of Styrofoam for the bottom, fill sleeve with dry ice then put another Styrofoam plug in the top of sleeve. ya have to have a small hole in the top plug, dry ice creates vaper so it needs some place to escape. Everyone I have done this way only had to drive it in about 1 1/2.
