Rob Posted January 28, 2010 Share Posted January 28, 2010 On an E6 series Mack engine during rebuild, does one have the block honed and thicker sidewall liners installed if there is a problem? If this were the case, then liners must be available separately and purchased as needed, per cylinder for sizing? I would assume the piston bore would remain constant, but liner height would be adjusted with shims? I've never had anything like this done before but kinda wondered.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Good luck tring to find that stuff these days thou! You would have to take what ya can get! Barry might be able to clarify this a bit as to what is still avalible!

I have a PAI kit that does not have liners and wondered why that could be. Stands to reason you would open up the block, then order liners after you know what you have. This is much the same as you do with matching a bore to a piston size. I've always had a block bored, and honed after having the pistons on gasoline engines.Thanks again.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Packer Posted January 29, 2010 Share Posted January 29, 2010 When I was at Mack in SLC, we did a bunch of liners (oversized) by boreing.The issue in the late '70's was the block 'Curing" out-of-round.The only way to repair them was to bore .010-.030 and even one at .040Took two weeks or better to get those liners.Like the man said, for a toy, just hone and run.Packer Quote Keep a clutchin' Link to comment Share on other sites More sharing options...
