my unloading augar on my Massey 750 combine is being problematic ,. after repairs that helped it is obvious the floor of the grain tank is terribly weak , this weakness continues to allow shift to the lower mandrel plate just enuf to throw the chain off of a 10 inch sprocket ,the mandrel axle will not settle anymore,according to the repair i made ,,.. best i can understand the leading edge is walking off . it just dont seem logical for the following edge to be coming off . it all happens so fast it is hard to determine,, this #50 chain is perhaps 10 or more ft long, the power side is coming directly under the cab from a 6 inch gear with a 3 inch idler directly behind it to titen , there are 2 anti slap boards at the 5ft wide midsection , this long area affords a lot of trial and error space.. i am thinking i can groove new boards and lengthen them to give the chain better tracking . i have considered adding idler gears. i need reengineering help from guys that understand fast moving chains
