Converting to the New Style Motor/Fan Coupling

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.

To convert from the old style motor-to-fan coupling to the new style, view the fan hub picture below. Next to the motor shaft are two raised tenons on either side. Cut these off with a hacksaw so the surface is flat. You can now use the new style coupling. These couplings will work with any of the gearboxes or fans.
