Charlie,

 

I think there is a difference (in diameter) between the automatic transmission flex plate that you currently have and a manual transmission flywheel. I suspect that the flywheel you bought is for a manual transmission engine.

Hi Charlie,

 

My flywheel was exactly the same diameter, thought the teeth were closer to the engine a little.  I think there may be a difference between the turbo and non- turbo.  We hashed all that out a couple years ago.. its in the archives.  You can also check the Mazdatrix website to see the different models.

 

Good Luck,

David Leonard

Well, I recently bought a used aluminum flywheel with 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 Non Turbo , its used and could use a new friction plate

fits 86-91 Non turbo RX7s might 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 figured it would be 'plan B' if I ever have an issue with the flex plate.

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 anything 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
