Vacuum Cleaner Bearings Question with Pics
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 !

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. -- Cheers, WB .............. "Vacillator" wrote in message ... Hi, I posted before about the bearings in my vacuum.

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.

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. |
