Cleaning cylinder sleeves

Olliejunkie · Mar 10, 2017

I picked up some cylinder sleeves. They have a hard yellow coating. Any one have any cleaning tips?

warm them with a heat gun or blow drier to see if it will soften if it does, it should then wipe out with paper towels. then use
charcoal lighter fluid or diesel to remove the residual. Jim

Just to add, if you are installing them in an engine use some hot water and soap
and scrub the bores until a white cloth stays white when you wipe them out. That is what
we were told in vo-tech and the way Ive always done it.

Thank you. Both good suggestions. I didn't think about warming them. Last ones I washed with soapy water but the oil was liguid still.

As mentioned diesel or something as such to get the first layer off is a good
idea.

Brake Clean would be my choice.

Janicholson · Mar 10, 2017

Good idea. I have seen cosmoline 1/8" thick. That requires a lot of brake clean. If thin coating probably a first choice Jim

I thought they were new sleeves but now I'm not sure. I have 3 different kinds out of a 77. I'm going to take the best ones and put in a 66. They clean up pretty good with brake clean.

Yes yes for goodness sake get all of that crud off. It will destroy
the seals in one swift move.

Here's most of the story..I bought a 77 diesel engine sight unseen. The gentleman delivered it part way. Someone had started to rebuild it and for some reason did not finish. I was not concerned as all the parts I got were well worth the price. I started going through the parts and some of the bearings are missing, head bolts, push rods and one of the rings. So I'm going to try to put my 66 together and save the other parts for my s77. Thank you for all the suggestions. I'm trying to figure out how to check the injection pump. I will probably pull it off and put it away.

Acetone or white gas - naptha. HTH

I agree 100%. I wash the bores of every engine that I rebuild with hot soapy water and dry them with clean rags.Coat them with oil so they don't rust and assemble.
