Auger Bushing Change

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

A piece of 1/2" black iron pipe should allow you to drive the bushing out of the pot housing. Put the new one in the same way. As long as you have the stoker on the bench, I could completely go through it and replace the auger (unless it was recently replaced). Check the fit & operation of the fines cleanout plate, the wedges might need to be adjusted.
