trying to get it ready for corn harvest and during wheat it was unloading really slow. well, we asumed that the vertical unloading auger was worn out and possibly the horz. one as well. we have it all apart and a new a&i vertical auger setting next to the old auger---there is less than a quarter of an inch difference in the flighting diameter. that tells me that its not worn a whole lot. the horizontal auger appears to be in good shape as well. currently i dont have a service manual for it but one is on the way. i looked in the 9610 manual to see what the tolerances for replacement on the augers is and i dont find it. they are the same size, so i would think they would have the same tolerances. the sprocket on the uloading system is the 17 tooth and form the jdparts website it appears its the higer rate sprocket. what could be the problem??? is this enough wear to cause problems??? the 9610 will unload lots faster.
