Inspect your grain tank for outward buckleing when it's full to see if the sweep drive sprockets are still in alignment. If so, adjustments to tie bars in tank can be tightened. Also check to see if flighting is bent enough that sprockets begin wobbling to throw off chain. If that doesn't work you can probably get a good deal on a 7720 if you like conventional machines! Good luck friend.
