I'm working on a 2046W whistle. I thought that I knew all the fixes but this one has me stumped. The motor worked but slowly making very loud noises of the type that usually mean "lubricate me" !!. It was already leaned up with good wiring. I figured out to lubricate the armature axle. One end is obvious - on the brush plate. The other bearing is more difficult, buried under the armature against the frame, but can see it with good light from the right angle.
After lubricating, the motor speed got fast enough to get the whistling sound. Problem is I still have a loud rattle as the fan spins. Is there a way to fix that, or are the bearings so worn that it won't rotate perfectly.
This is a tender that I'm fixing as part of a 1952 675 to sell. I'd can say the whistle works, but if I cn't fix the rattle, I'll have to include that in the description and hope to find a buyer who isn't a fuss about whistles. But it hurts my aesthetic sense to have to do that.
