Harman Mark II Fan

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Since oil holes are not provided it probably needs to be disassembled. It's a bushing motor, the armature shaft ends ride in bushings, that's where the oil is applied. The only other maintenance is to blow out the motor with compressed air to get all the dust out that can cause the motor to overheat.

Clean the blades of the squirrel cage with a toothbrush or small wire brush if there is build up on them.

ON my hyfire, it had a ton of gunk on the blades, took a while, but seems to put out more air now.

Usually there is a HEX Allen setscrew on the squirrel cage and you can remove it quite easily.

Mine have a Torx set screw. Took me about 20 min to finally decide it wasn't an SAE or metric allen screw.

You can use a allen on most torx.

Most of the time can use the Right Angle part of the allen wrench to get to the screw, on the combustion blowers and others you have to go in thru the exhaust opening and thru the fan blades to get the screws.... :)

I guess I have to take a closer look at my blower motor. You would have thought I'd have noticed them when I installed the switch in the collection box.
