Combines 750 Vertical Unloading Auger

No Easy way to get it out. Remove the bolts at the top holding the elbow on. Hopefully the 0ctagon shaft that drives "through the elbow " is not siezed and the top section will come right off (not much chance though). Remove the unloading auger drive chain. Remove the 3_8" bolts in the very bottom of the bin inside the auger tube. These will probably have the heads worn round from grain so you either have to torch them or somehow get a pair of vice grips on them. If you torch them, be very careful not to cut the sheet metal part of the bin. I also believe there is a 1_4" pin to drive out of the lower Octagon drive shaft. If this shaft is not siezed, the cast iron drive gearbox should drop and then the auger can go out the top of the tube. While you have it aprart, check the bearings in the lower gearbox and replace as necessary. Especially check the lower seal that keeps grain out of the bottom bearing. I had a terrible time with this seal on my old 750 red cab.The seal is basically a cupped washer welded to the lower part of the auger if I remember correctly. Good luck. It's always hardest the first time you do it. By the way, make sure you have the vert. auger supported when you remove those 3_8 bolts just in case it falls down when you are under there or have your hands inside the door. The sheet metal bottom of the bin should prevent that but you never know.
