The Bracket that holds the Hyd motor that runs the fan keeps coming out of the hub with the rubber "bushing". Done it a couple times now. When I put the cylinder in gear the bracket and motor really shake. Welded a gusset from one side of the bracket to the other, still shakes. Took Hyd motor off and hand spun fan, turned free and smooth. Anybody with help or ideas are welcome. PS. Bought this combine 3 weeks ago, new to this series of machine. Ran all 2388 before, also from Oklahoma with drought wheat 30bu is best number on moniter. So no grain getting in fan, pushing a 40' 2162.
