I have no idea why it did this either. I don't randomly spray stuff around in fear of things like this happening. I was told by another guy offline he used it on weapons too. The fan motor was cleaned of dust and dirt with high pressure water (a few days before tri flow was put on) then left it to dry in the sun. After, it ran fine (pre tri-flow) and I used a fairly small amount. I do this maintenance to all my house fans once or twice a year. (my buddy garbage picks and cleans even more modern fans the same way. The majority come back to full life)(Ive cleaned mother boards for coin-op games in dishwashers too) My point being it was "clean metal". I even considered a hidden plastic washer or shim melting from heat or chemicals. But the fans twin has none.
Maybe it wasn't the heat, or a mix reaction. Maybe the motors electric field changed it?(and/or heat/chem.) That, or my dishwasher has machine tuberculosis and coughed red gunk on the fan.
My favorite non train lubes? Best spray dry lube ever is Boeings T-9 airplane aileron lube also w/Teflon. It did things I couldn't believe including initial penetration. And lasts a loooong time out in the weather. But 10+ years ago it was $25 a can. Now?
Aerocroil- (? on the spelling) Only a little more $ but really out does PB blaster and Liquid Wrench for penetrating. Ive only seen it in industrial supply outlets, but its been around a long time.
Thanks everyone, the fan seems happy again so I think Ill just flush the Hudson and keep close watch.
Jake, I'm still jealous you got in.... and yet happy for you. Ill be lookin for you at the shows on the south side of town. Be prepared for a (mild) punch in the arm
Oh well it did happened and Ive warned you
