Forgot to add the shot of the brushroll in the Royal.
If the staple fits the hole it's the right size.
I make my own staples, since I live in Middle Earth it's Elven magic.
If you have a plastic bridge over the back of the motor instead of the metal casting you will have ball bearings at both ends of the armature.
Sorry I can't remember if the started the plastic bridge with the Silverado or it was later.
The rear bearing fits into the plastic bridge and there...
I wanted to make sure we are talking about the motor in the Silverado. It uses the same motor as the Super J.
If you look at the back end of the motor it will have a cap over the end of the armature. Under that cap will be a felt disk that has oil on it to lubricate the sintered bronze sleeve...
If you go to ebay and search on Hamilton Beach Vacuum Cleaner there are brochures for the hand vac from 1939 thru 1950.
There is also a set of attachments for the hand vac in a stunning blue in the original box.
Where the bristle is missing, does the hole go into wood?
Meaning that it is a wood roll with a metal covering.
If this is the case the bristles are held in with staples.
