Does anyone have a source for a convection blower for a Hudson River Niagara pellet stove. The stove works well but I have had to acquire a new convection blower every year. The bearing is bronze mounted in a rubber grommet and isn't easy to lube. I would like to just buy the bearing if possible to save a few $$. The OEM fan has a 3 week lead time because the stove isn't manufactured any longer.
