2.7t Main bore housing spec

[Kehl]

Hey all, taking an engine machining class at school and doing a 2.7t. I can find the main bore housing oil clearances, but can't seem to find the overall bore spec for align honing it. Anyone have a reputable source on this? Thanks!

Don’t think that info is listed but you could just measure it.

Not sure if it helps but from my notes I have
Crankshaft main journals 2.5585. My oil clearances were .002”…so with bearing in the mainline it was around 2.5605.
Don’t have the bearing thickness recorded but if you have that you can add it to the 2.5605 to get a rough idea.
