Default Vacuum Cleaner Bearings Question with Pics

The "pill box" item on the left end of the armature shaft (next o he fan
blade) is a ball-bearing assembly (or simply ball bearing, to many folks).
The ball bearing on the right end has failed, not just had the balls fall
out.
It's very likely that the 2 ball bearing assemblies are the same size and
type.

If you look very closely at the ball bearing, there is likely a number on it
to use for choosing a replacement part.
The ball bearing is likely to be a double-shielded type (not sealed), and
permanently lubricated with a grease.

The part on the right end of the armature shaft that has a half-round groove
in it is the remaining inner race of the failed ball bearing.
Generally, a bearing puller and/or a small press is used to remove and
replace ball bearings in small motors. A vacuum cleaner shop may be able to
replace both bearings for you.
A bearing supplier (yellow pages) would be able to measure the old ball
bearing (if the number isn't legible), and get you replacement bearings.

An improvised method of removing bearing races from shafts (particularly
since a bearing puller can't grip it) is to cut them with an abrasive disk
(such as Dremel) to nearly the full thickness, then tap a hammer on a chisel
placed in the cut.

If there is no other damage from the bearing failure, paying for the cost of
having 2 new bearings replaced should be worthwhile.

Repairing equipment can be gratifying. You're sorta lucky/fortunate that
this motor has replaceable bearings.

Hi,

I posted before about the bearings in my vacuum. I now have pics
also. I almost bought a new vacuum, but thought I would give the
repair one more try.

To recap, the ball bearings have actually come out of my vacuum
motor shaft. I am trying to figure out where they are supposed to
go. Also trying to figure out if I need to remove some sort of "race
and bearings" assembly on the shaft and replace the race and bearinigs
as a pre-assembled unit ( and where to buy it).

The ball bearings are silver and are smaller than beebees.


I have 2 pics, below. Shaft, and motor.

The round pill box shaped thing on the left of the shaft, next to the
fan, works great, spins freely, and is not the problem.

The lost bearings, I presume, are supposed to go on the right side of
the shaft somewhere. Maybe near the loose washer.

Anyone who can help, please feel free to chime in !


Thanks
