Piston Sleeves

[Schtick]

I'm overhauling a D1105 3 cyl diesel that had a cracked head. Water sat in #2 cyl and it was seriously corroded so I have to replace the sleeve and the piston.

I thought that when the new sleeves came they would pretty much be ready to install but instead I found that inside wall of the sleeve had small very pronounced ridges from the top to the bottom. I'm trying to figure out what that's about. I've been using a cylinder hone buts its slow going. Am I missing something? Is possible there some kind of shipping or protective surface applied to the inner wall? I've attached a photo of it

Am I missing something?

Yes your missing a boring machine.
The sleeves are semi finished and need to be bored to size AFTER they are installed in the block.
Doing it with Normal hone will NOT work.
1: It would take you forever to get it to size.
2: It will not give you a round cylinder.

Don't use!

There is a boring hone that will work but they are pricey.

You can do it with this:
Warning you will need several sets of different stones of various grits to do it, and it is a VERY slow process with a very good drill!
