As a follow up to the above I got the part in the mail and it was the wrong part. I returned to the farm store and we looked up the part number specifically. It was 43-34-0935, inner disc flange on bulletin number 54-38-2200. We re-ordered the part and it came in a couple of days. That did the trick. It looks flat. Great customer service. PS the case is a nice one, it has a padded bottom.

The best 4 inch grinder on the market Rated 5 by Anonymous
I run a fab shop. I love these grinders for smaller jobs. They are easy to use, well balanced, single hand operation, and durable. They last about five to six years of continuous use. Don't settle for grinders of another color such as orange, green, or yellow. Especially stay way from orange they are unsafe. I would and do recommend these products to everyone.

I got this at the local farm store and the price was right. The box contained a grinding wheel and a case which is nice. However, when I used it the first time it seemed like there was a bump on the wheel. It would not grind smoothly on a flat surface. When I looked at it I saw that the flange (not the flange nut) was not of an even thickness and it caused the grinding wheel to wobble. I would guess that the difference was about 1 mm. And caused about a 3 mm wobble. I could see it wobble when it coasted down. I returned to the retailer and took the flange off of the display model as it looked straight. The retailer also called the manufacturer and ordered a new flange to be sent to my home. When I got home and used the flange from the display model I could tell right away it was better. I grinds rust off of my trailer hitch pretty good. Must have been a bad batch of flanges. PS I wish there was a way to tighten the side handle with a wrench and not just hand tight.
