Nope, too late now. :P

I'm picking up some locally in a few, a friend of mine has new ones for sale.

Shouldn't be too critical right? I just noticed they were in the dead center of the breather hole.

That breather hole has nothing to do with it. It'* actually a compression relief hole so when the bearing is pressed in, it doesn't compress air behind it. And it'* location can be random. It'* not a precise reference point by any means. And are the local ones pregreased? If so, with what?

They're not pregreased, someone suggested axel grease.

I know what that hole is for, seemed like a good reference point to me. *shrug*

Is there a standard tolerance for it or anything?

Standard tolerance is you measure them first, then pull them, and press the new ones to the same depth.

Axle (not axel) grease is the WORST thing you can put in there! Don't do it!

You need rheotemp 500 or get your grease from INTENSE, but you could have just gotten the right pre-greased bearings now.

If I wanted you to fail, I wouldn't be asking you these questions. All this information is already here. This is why I suggested 3 different vendors.

The rotors spin at 11,000 rpm'* MINIMUM. No other grease will withstand the friction and heat.

Get the right grease, or order pre-greased bearings.

The point I'm getting at is that they could be pregreased with peanut butter for all we know. The grease is very application specific.
