Combines HelpIJIJIJ Bin Unloader 97 R 72 IJIJIJ

We've used a grain vac to clean out a grain tank.

if you can turn the sprocket by hand the shaft might be broken off just inside the grain tank(fairly unlikely).the flighting is on that shaft. if you cant turn it there might be a problem a with the ujoint or just above it with the shock absorber.our combine had a shock absorber that would twist up and dislocate the rubbers inside it and cause the chain to break and the flighting in the unload tube to jump around like crazy. a grain vac is your best option to empty it out.

the drive shaft on the right end is just a stub shaft and is locked to the cross auger with 2 bolts.........almost sounds like this is your problem.
