Combines F2 unloader flighting

We bought our through Replacement Flighting Supply and got there thicker flighting for our F2 last year. We now have a M3 so i can't get measurements for you. Here is the link to there site: http:__www.rfsaugerflighting.com_replace.htm There is a large gap of 1_2 inch in the unloading auger between the tube and flighting edge. I think the unload tube on the F2 is 11" so we ordered 10" dia flighting. The bin auger is smaller than the unload tube. We ordered ours too big and had to grind to make it fit. Measure the closest distance from the tube center to the bin floor. this will be your radius. Diameter will be radius multiplied by 2. You will want about 1_2 clearence with the new flighting. I think we ordered 9" but should have been 8" or 8.5 inches instead. Replace the unload auger bushing and universal cross while your at it. Jason

Thanks.I think the tube was a shade over 10in but I understand what you're saying.That big gap seems wrong but appears to work ok.Agree on the bushing and cross.
