Has anyone noticed the rave shows 2 different sizes for rod journals on the crank?

workshop manual - 4.0 specs - crankpin journal 2.1850 - 2.1855"

overhaul manual - 4.0 rod big end - 2.20 - 2.22"

I've always known the "crankpin" to be the rod big end.

I'm going to throw a set of bearings in as preventative maint. soon and that's a big diff.

Yea, something is definitly up with that. I would trust that first number, but the second? .020 variance? That tolerance is way outa the ballpark for a bearing dia.

I have learned to always double check what the rave says. I was looking up my fuel pump relay recently. Supposudly in the pass. footwell area. Nope. It's under the hood. And it's like a $100 assembly, not a $7 relay.

 

Since they come from 2 different sources I would suspect the overhaul manual is taking about .020" oversize bearings as opposed to the standard bearing size in the workshop manual.

 

It would have been too much for them to state that.

Both references list the same metric size, tho"

I also don't like that they state do not re-install old bearings, didn't they ever use plasti-gauge?
