Fixing An Old Furnace Fan

Wiring and rusty contact problems were most of what I had to resolve. With a little hardware to replace some missing screws and nuts, a little belt tightening and some oil for all the bearings, this fan is going strong once again.

you should clean it up and paint it

@wow1022 Nah, it's OK with me as long as it is electrically and reasonably mechanically sound.

who is the key keeper

[uxwbill]

@youyou5923 A brother of mine.

thats an older Dayton motor, pretty similar to mine, it is a nice fan.

[uxwbill]

@isethaitchison This fan works great, and my opinion of Dayton motors has always been high.

thought maybe you would put it in the dishwasher haha

Dayton motors have come from a couple different manufacturers through the years, mostly Emerson, and they were mainly sold by Graingers. Some years back I started seeing Dayton motors coming out of Mexico. Now Chinese motors are sold with a Dayton label. Sad, very sad.

I love them old blowers! Usually if you reverse two of the leads in the motor it just changes the rotation of the motor ive found. Usually I find the tension adjuster on the back of the blower opposite of what yours has, but I guess it depends on how it is installed in the furnace. Great vid!

Hi Bill, you missed one thing.. a shot of ZOOM SPOUT OIL in that little yellow cap on the bearings.. :) you should keep some in your tool box of things for next time. Good deal fixing it up.. its a much happier motor indeed! love it. Keep up the good work friend. Peace

He must REALLY want those terminals clean!

Since we both seem to fancy electric motors perhaps i should take a video of the motor on my 1940's shop compressor. It's an ancient "Delco Motor" non-capacitor start 1 1/2 horsepower motor running at ~1725 RPM pulled 10 amps at 220 volts. The motor is huge to say the least. Has a lovely startup sound to it as well.

Interested in a video?

@fattpill the setup he has moves the air for $140 less than the power flight blower you're talking about.

[fattpill]

Power flight makes a Blower for about 150 dollars and it will move as much air as that furnace fan

Thanks for making this video. I can think of one great use----drying out wet carpet/flooring. Try buying one of those fancy high volume air movers for carpet--big bucks! This is a great idea on that alone.
