Cheap sleeve bearing computer fans are evil. :) I've taken many apart and lubed them. Sometimes they last, sometimes not. I've also found that, in some cases, thier idea of a "ball bearing" fans is a ball bearing at one end of the shaft and a sleeve bearing at the other end. Not really an improvement. >You might also ask to see if someone, possibly a different ham, would >be willing to relubricate the bearings for you on the old one.

Removal is not difficult, remove four long bolts and the fan cover, unplug the fan. It does require removal of the top cover of the amp to get to the nuts. I was thinking like you, but I found no easy way to disassemble the fan. Lifting the label revealed no secret screws, clips, bearing dust covers, etc., that one might typically find in a "computer fan". Maybe Evan or someone else has had one apart and can tell us how to do it. I would like to lube mine, as it is starting to sound a little rough. The fan is a Torin TA450S, Model A 30390-10, 115VAC .12 Amps. I couldn't turn up any specs on it on the internet.
