Re: Vacuum Cleaner Bearings Question with Pics

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.

Shroud off (woven glass mat etc) any plastic etc and blast with a hot air
gun followed by "hub" puller.
If no shift try again , following the heating with shrouded off blast of
freezer spray on the shaft only then puller.
Then puller up to its limit of pull.
Then butchery

what make and model?
The fact that the motor's bearings died before you had even one brush
replacement sounds like it is an electrolux. If that's the case, you should
just junk it unless you have a special attachment to french garbage.

If this is the ball bearing on the left end of the shaft you're talking
about, this may be identical to the one that exploded on the right end of the
shaft.

The grooved ring just to the right of the washer looks like the inner race of
(what used to be) a ball bearing.
Look in the housing where the right end of the shaft went through. There
should be the outer race (look at the bearing on the left end of the shaft to
see what the outer race looks like). The missing (exploded) bearing on the
right may be identical to the good one on the left.
Tap out the outer race of the destroyed bearing from the housing. There is a
part number printed on this. (Look on the left bearing; if the bearings are
the same size, you can use this number to order the new bearings.)
Take the shaft and the housing (the one that the right end bearing fit into)
to a bearing distributor and see if they can get you a replacement. Should
cost less than 10 bucks. (Look in the yellow pages for bearing distributors.)
You want *sealed* type bearings. These have a neoprene-like grease seal on
both sides of the bearing that protects the balls from dust and dirt which
destroys bearings.
I'd replace the one on the left end too. That way your vacuum will last for
years.
Measure the exact location each bearing is on the shaft (measure from the end
of the shaft to the bearing). This way you will be sure of their exact
location when installing the new bearings. (Note that there may be a "step"
in the shaft where the bearing is located against. This means that
measurement of the bearing's location isn't required; when you install the
new bearing you just tap it on until it reaches this step and cannot go any
further. "Automatic" location.
Pull off the old bearing or remains of it any way you can (hammer, bearing
puller, vice grips). You're going to throw these away, so don't worry about
being gentle with them. Just don't mess up the shaft.
Tap the new bearings on using a punch, drift, chisel, or a screwdriver and a
hammer. Tap *only* on the inner race (the part that slides onto the shaft.
When installing the bearings do *not* hammer on or force the outer race in
any way. This could damage the bearing.
Good luck.

Just an update on the Eureka vacuum situation. I took the
disassembled motor down to my local vacuum repair place, hoping to get
a new bearing or 2 installed, but the guy said a used motor would be
cheaper and better. I went with the used motor, especially since the
old one was sparking quite a bit, anyway. The used motor was only
$15. Not bad. Installed used motor today. Works great. I kept my
original motor for spare parts, if needed.
Thanks for all the good advice along the way.
