Blower 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.

I have a blower fan in the back of my Mark III. It blows cold air through ducts and heats it and warm air comes out the front. The fan is old and seems like it will seize up very soon. Any ideas on how to make it last longer? I.E. take it apart, clean it, and put grease on the bearings and re assemble it? A new one is expensive and I want to save money on a new one. What kind of grease should I use?

remove it... compressed air the hell out of it for starters, I think its a Fasco and Leisure Line uses these as well (prolly a *censored* load cheaper than going to Harman for spares!) ... but anyways... Leisure Line web site does have some basic instruction for care and oil of Fasco Blowers I think. If its a sealed Dayton or other maybe just post pics and model so we know what type you have. as for all of them the #1 thing you can do is used compressed air to every season to keep it clean and dust/debris free.

If you think it's about ready to go, it's probly too late...

If it's a Dayton, and proby is, it doesn't have any oil cups, and is difficult to oil.
What I do, is use one of those hobby type oilers that looks like a hypo needle.
You can see the shaft and where it enters the bearing. Put a drop or two
right there, and turn the motor so that gravity helps the oil get
into the bearing. Do both ends...
One of those areas where more is not better.....

eBay has them for around 65 bucks...

electric motors are easy to service and lube, take it apart and fix it. bearings and bushings are probably dry ? make sure the intake screen is clear, if clogged with dust, it makes the fan struggle
Coal stoves without fuel, are heavy, expensive decorations. Are there any coal mines in YOUR home state ? If you talk the talk, you have to walk the walk.

I use Holden's, the Original Zoom Spout Oiler. For all appliances and motor bearings up to 3 H.P. Most heating supply houses carry it or something similar.

Rich, I always oiled the Fascos that come with the Mark series with Amsoil motor oil. I think I used 20W-50 motorcycle oil last time. On the stoker I used 5w-30 Signature Series, since that one doesn't get nearly as hot as the one on the Harman.

Isn't that sort of relative to the mechanical ability of the owner :?:

True that. Also, I kept oiling and spraying and doing everything to keep my fan running minimally........and loud, for years.
I finally broke down and bought a new one 2 years ago. Wish I did it sooner than later. :P

Got it here for about $96 with shipping.

What makes you think it will seize up very soon? Has it become noisy? The squirrel cage fan they use accumulates dust in the curved vanes and it reduces its efficiency and may make it noisy. Remove the screen cover and clean those vanes carefully. I use Q-tips and rubbing alcohol. Be gentle with the vanes. You don't want to bend them, hence the Q-tips. An air compressor to blow out the housing is also recommended.
