Nope, brass = bad, lots or brass = really fucken bad

 

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..

 

Looks like somebody has found a new business niche.

 

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.

 

yah thats the problem with the fd bearings is that they dont list the orginal size ANYWHERE. the pre fd bearings only come in one size

They are around a $100 for each set, one for the rotors and one for the stationary gears.. It took ours about a month and a 1/2 to get here after we ordered them.. If you want I have extra stationary gears that I can put bearings in and send them to you... I also have rotors, but I don't really want to sell those..

 

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.
