Posted by JR North . The following description was provided: ================================================================= Notes on rebuilding a Kerosene Heater. This heater was about 30 years old, and had been sitting all that time. The motor was seized up, and the air pump worn out. There was severe rust and the fuel system was totally clogged. AIR PUMP: This is what usually wears out, rendering the heater inoperable. Many units are simply thrown away when this happens. The pump is easily overhauled with access to the right equipment. The rotor housing was machined for a rotor side clearance of .003" and trued up. The motor plate and pump intake plate were machined flat And the rotor and blades were conditioned with emery cloth. Design output of the air pump is 3 psi, but after my close tolerance rebuild, it pumped close to 7 psi. The air bleed adjusment when backed all the way out will just barely lower the output to 3.5 psi. I replaced the heater housing with a 7" galvanized duct section, which worked perfectly.
