Flywheel Ring Gear

Folks, I'm replaciing the ring gear on the flywheel of my 52 8N due to damaged teeth. The tractor is at a remote shop at the moment and I will not see it again before Friday.

My replacement ring gear from A & I (Yes, I know) arrived today and the teeth are beveled on neither side.

IIRC, the OEM ring gears have beveled teeth on the starter drive side to facilitate engagement, but, again, I will not again see the tractor to verify for a few days.

I suspect that all of the Chinese made replacement ring gears do not have beveled teeth but am not sure.

Anyone know? If so, anyone know where to get one with beveled teeth?

Have posted in N Forum but posting here as well as, IIRC, the same ring gear fits all 4 cylinder gasoline powered Ford tractor engines 39-64.

I bought my ring gear from CNH (Munn Tractor). But that was twenty years ago. Maybe your local dealer has a ring gear in stock you can take a peek at.
 
This is a pic of the ring gear I installed a few years ago on my 640.
No large chamfer on either side.
Also shows the Bendix I'd installed a few years prior. Length of teeth was to short and it chewed up the old ring gear.

It looks much like the one that I have from A & I.

From where did you get it?

Dean,

Here is a few pics of the ring gear I installed on my Ford 640 earlier this year. I bought it from the local CNH dealer at a cost of about $61, part was in stock. Ring gear part number 9N6384 and is beveled. Made in Italy.
