Ridge reamer on .040 sleeves

[FarmerHR]

Will a ridge reamer work on steel 0.040 sleeves ?
Are there many special steps if the ridge reamer can be usrd on 0.040 sleeves ?
Thank You for any help !

Sleeves are not intended to be reamed. Most likely the .040 sleeves would break if you try to ream the ridge off. If they have a ridge it is time they are replaced. If you do get the ridge reamed off and install new rings most likely the rings would not seal properly because the ring to sleeve clearance would be to great. Replacing the sleeves is such an easy job that doing anything else just does not make good mechanical sense.

while i don't think you'd have a problem reaming a ridge on a thin sleeve.. if it's a big ridge.. you know the sleeve is about gone.

not much technology to a ridge reamer....

Why bother? Sleeves are meant to be replaced.

Thank you for your excellent thoughts.
I plan to replace the sleeves because they are quite worn. My thought was that if I could ream the ridge out, it would be easier to push the piston rod assembly out of the block from the bottom. I was concerned that the rings might hang up on the ridge and make removal difficult.
Will the rings hang up on the ridge ?
The worst sleeve has about a 0.020 ridge which is also not concentric. About 0.005 on the slight side and 0.015 on the most worn side. Will a ridge ream work on 0.040 sleeves ? I suspect they are harder than cast iron sleeves and may not ream well.
Thank you in advance on any suggestions you might have.

Farmerhr........would you believe you push the sleeves UP thru the top of the engine??? (there is BIG LIP on top of the engine sleeve that fits a groove in the top of the engine) And you pull the pistons down thru the bottom of the engine after you remove the crankshaft. Simple, eh? .......Dell

If they don't pop out easily you might use a dingle berry hone to help soften the sharper underside of the ridge . A common 4" hone will smooth a 3.2" hole very quickly .

A three stone glaze breaker hone will probably not help much . If you are not going to reuse the sleeves , then a stone on the end of a drill would work good too .

Thank you for your help. Your suggestions were really a help.
Since the sleeves are not reusable, I plan to break the edge of the ridge with a die grinder and then try to push pistons/rings/connecting rod out the top. The ridge is really sharp.
Will let you know what happens.
Thanks again !
