whistling sound on start - old Kirby

[vap0rtranz]

My old Kirby 561 started making a whistling sound on 1st start up. The whistle goes away after a few seconds.

What would cause this sound?

My uninformed guess is a bad bearing or something needs lube/grease ...

I've searched Youtube vids of vintage vacs but not found anyone talking about this sound.

Good, I may have a bearing for this model already in storage so I'll try that 1st.
