Liners:

[Rob]

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

Yes correct Rob!

The liners are or were availble in oversize dimensions I beleive ( Don't quote me) 2 thou steps up to 10 thou and ( Maybe a bit larger) increments. 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!

Thanks FJH. 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.

Chances are if the liners come out fairly tight Most of the way out you can just hone and reinstall what ever size came out!If this is a hobby engine I would just hone and reuse the liner as long as it hasn't too much wear!just Leave them in the block!Just my opinion!

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 .040

Took two weeks or better to get those liners.

Like the man said, for a toy, just hone and run.
