I think there is a differen= ce (in diameter) between the automatic transmission flex plate that you cur= rently have and a manual transmission flywheel. I suspect that the flywheel you bought is for a manual transmission engine.

Hi Charlie,

=C2=A0

My flywheel was exactly the same diameter, thought t= he teeth were closer to the engine a little. =C2=A0I think there may be a d= ifference between the turbo and non- turbo. =C2=A0We hashed all that out a = couple years ago.. its in the archives. =C2=A0You can also check the Mazdatrix website to see the different models.

Good Luck,

Well, I recently bought a used aluminum flywheel wit= h the following description:

Quote:
RX7 8.5Lb Fidanza= Aluminum Flywheel for FB or FC
For sale is a 8.5lb Aluminum Fidanza Flywheel for a RX7 No= n Turbo , its used and could use a new friction plate

fits 86-91 Non turbo RX7s mig= ht fit Fb 2nd gen RX7s as well i'm not 100% sure

Unquote.

It was reasonably priced, since I don't need the wear surface, so I fig= ured it would be 'plan B' if I ever have an issue with the flex pla= te.

When it arrived (yesterday, after everyone was gone), I sat it on top of my= (cracked) flex plate, and it's almost an inch smaller in diameter. The= mounting holes in the center seem to line up properly. I remember reading = about milling the drive plate to move the starter .2" closer to the engine, but I don't remember anythi= ng about the smaller diameter.

So, my questions:
Did I purchase the wrong item, would I simply make my starter cutout in the= plate closer to the centerline to account for the smaller diameter, or was= the flywheel mis-represented?

If it's not the described item, I need to send it back, but I don't= want to bother the seller if I simply bought the wrong flywheel.

Thanks,

Charlie
