Are you sure about that? Specialized themselves say it's a standard BB30 and will fit any BB30/PF30 frame... BB30 and OSBB are both 68mm wide.
The Weenie formally known as CAADHEAD
It's not lining up to allow the Hirst joint to seat properly without binding?.....sounds like a fractionally mis-aligned bearing to me. They can be out by the merest fractions of degrees and run badly.
Edit: 2015: darn near won the best South Island series (got second in age
-group)..woo hoo Racy Theremery is back!!
The next step would be to have a look at the exploded view or installation instructions. Make sure you've got the bearing covers and wavy washer in the correct positions. I recall there is a flat and a curved bearing cover so that may be the difference, or you may have the wavy washer on the wrong side of the bearing cover.

I'm going to remove the bearings and re-press them (and yes, using a BB press). Hopefully, it's that simple.
It's either the wave washer or the preload washer with the 3 small set screws on the NDS, you are not suppose to use both.
On the DS, there should only be a bearing shield
There should not even be a wave washer supplied with the adjustment ring, so that's a little puzzling.
How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.
Haven't had a chance to re-press the bearings, but I'm hoping it's that simple.

Then sounds like a misaligned BB cup, although the alignment issue could be with the bearings, but that is doubtful. It's a frame warranty issue. I would not let a shop try to reface/chase it. From what I have read that can only lead to more issues with poor fitting. Ask for a new frame.
