New woodstove has not arrived at the dealer yet so I'm trying to make the fan system (dual squirrel cage blowers on the front) last until the new one is installed. One of the fans started squealing the other day so I took the whole thing out to the shop. The bearings for the fans are quite well hidden between the frames of the motor and the baffles of the fan cages, couldn't get oil down to the bearings by the "guitar string method".
Looking at the lube shelf of usual spray/pump/drip/squirt products I remembered I had some PB Blaster that I got last summmer after reading a bunch about it on this forum. Shot some of that stuff with a "red straw" attached on the bearing vicinities and let it sit for 10 minutes.
Quieted that fan right down! Thanks a million to all who've posted about it. It now will be IN FRONT of the WD-40 on the shelf!
(Of course when some of that stuff worked it's way into the air jacket of the stove Wifey noticed the aroma right away... But, living with me she's fairly used to all manner of oderous vapors in the house both inorganic and organic. Opened some windows for a while and that has pretty much quelled both our nausea problems.)
