Good day everyone. I need some help. My auger broke last night and I want to fix it but I am lacking the knowledge. I know i need to get the auger out to fix, the question is how. I drew up a little sketch to show my conundrum.

So I see my first mistake was to build the bin to tight so as not be able to slide auger away from boiler to get out. But it just doesn't make sense to me that that would be the only way to get it out. One post said that you would dismantle the bottom of the bowl to slide the auger. I guess I don't understand this because the hole in the bowl that faces the gear drive isn't big enough for the auger to slide. I have 2 lengths of auger and they are not connected any more. I feel 1 length moving in the bowl, but after digging out the coal in the bin I can feel that the bin end is not turning. I am very lost and in need of help. Any is appreciated. Thanks

If you have coupling that looks like the picture on the link above there should be a auger coupling under this when you take it apart and you can't take the auger apart here I believe is is left handed threads but someone should check me on that . it you have a two piece auger and you don't have the coupling its going to be harder .

I believe your only option will be to cut the bottom of the bin out and replace it with a removabel plate in case of future problems , or remove the stoker mech from the auger tube and then remove the auger. Cutting out a section of bin floor may be easier.... If you go the stoker route you will likely need the old smoke wrench ;)

If there are two lengths of auger attached to each other in a single length of pipe, how about cut the auger pipe at the location of the auger coupling and install a pipe coupling there?

Just wanted to thank everyone for their help. Wanted to find an easier way to get to the problem than shoveling out 2 1/2 tons of rice coal to get to the problem, but no way around it. between the floor of the bin and the coupling, I found the splice bolt and put it back together, and I am happy to say the auger is now feeding. I do have a question for future reference though. Where does one order replacement augers?

I am not sure what you mean by the splice bolt. There should be a threaded coupling that connects the two augers, it looks like this:

You can get augers from any EFM dealer. The guys that handle a lot of coal units might have some "low mileage" used one available, or you can have new ones drop shipped right to your house. If you are going to replace the pot auger, you should probably replace the bushing in the pot as well.
