got an 05 2388 with 642 hours on it. started wheat on sunday. cut 30 acres and had a pile of wheat on step on right side by tailings elevator. looks like it is possibly coming from grain tank and sliding down tailings elvator. siliconed two possible leaks and it has not helped. starting to think i have a hole in clean grain elv. when i got machine one of the rubber paddles was broken and when you ran it is would slap and knock like crazy...could it have rubbed a hole some where?...thanks.
