The only brass he sees is at the seam which is what is done by mazda to even out the seam. And yes, the mazdamotorsports tech section does say to leave the main bearings alone if they show wear in 50% area or less as they would already have an additional clearance for oil flow. Now egg shaped is a different story.

a new stationary gear bearing is around $35 or so, the rotor bearing is about $30. If your pumping a couple of grand in to a overhaul it's always a good Idea to spring the extra $130's for all new bearings. your only problem is finding the special press tools to pop them out and put the new ones in. If you not in a hurry and you pay the shipping I will do it for you. At the least do the stationary gear bearings as they see the most stress... If you want I'll even order the bearings for you here if you send me the $ for them, you just tell me the ones you want.. PM me if you need help..

I appreaciate the offer but I think I could buy the press tools for less than what it would cost to ship the rotors to Japan.

do u have pics of any egg shaped bearings?
It would be pointless for me to post a picture of my front stationary gear. It is out of round in the thousandths of an inch. It is not apparent visually, I only noticed it when I measured it with micrometers.
