Northern Illinois | I think its aggravated by the start with the unload full. Running the tank/unload completely empty helps but once in a while you don't have a choice. We replaced the 3 female and the 2 males in the horizontal, balanced and UMHW the flights. Also bearing, seals and the 2 spline/bevel gear shafts in the 90. The next year we changed the spline/bevel drive. UHMW the vertical. Also check the shim (if needed) on the top of the vertical to hold it down. Also IIRC the drive, 90 box and spline are the same in the HUR and standard. This was on a 680 Good Luck |
