Noise making me nervous!

[electroluck]

Hi all!

I have a collection of olden hoovers from days of yore. Included in them is one of five convertibles. It's a cute little yellow thing that I have enjoyed using ( I use them all!). Lately it has started to sound pretty sick. I don't know a thing about motors but it might need the doctor. When I turn it on, what used to be a deep hum has now taken on the timber of almost a high pitch whine, a lot like a car sounds right before it's gonna shift into another gear like revved up. Any thoughts about what could be causing this? I wonder if it's an easy fix? There is an A-1 Vacuum shop where I live and when I take it in I hope to sound a little like I know something. Any input is greatly appreciated!

Dry bearings... Hair on Beater bar....

Ok first of all, beater bar probably has stuff in bearings like hairs. Need to be cleaned and repacked. The top sleeve bearings don't really self lubricate themselves and need to be oiled. Lower bearings probably need a cleaning and re packing. Make sure belt is good. Make sure there is no broken fan blades. Its definitely strain on bearings somewere.

Sometimes threads can get on the belt pully causing that sound. Either way wouldn't hurt to have all the bearings serviced anyway.
