Replacing a motor in Electrolux XXX

[jo]

The more in my Electrolux xxx which my grandmother bought new when my Dad was just a kid works but the bearing lubrication is dry so it seems to run slower than it should and doesn’t quite have the optimal suction power it should. Using a brand new vinyl hose so that’s not it.

I know there are tons of model L’s out there and they have great motors in them and wondering if I can put a model L motor in my XXX and will it fit right in? I don’t have a model L on hand to try it out.

Let me know if you know.

Perhaps it’s the bearing

Maybe the bearing needs lubrication in my XXX. Anyone know how to do that?

If you look at the rear bearing you will notice a cap over the bearing held on with two screws. If you unscrew the two screws the cap will come off and you can add grease to the bearing. The front bearing is the same BUT you will have to take off the fans. To get the fans off you will notice three screws along the edge of the fan housing, they hold the fan housing covers in place. You unscrew those three screws to get the fan covers off (don't lose the small nuts at the end of the screw). Once you get the top cover off you have access to the first fan. Wrap something around the fan and take the nut off the end of the armature shaft. You can then take off the fan, remove the lower cover, take off the second fan and gain access to the front bearing. You will see the same two screws as on the rear bearing cover. Once you take off this cover you can add grease to the front bearing. When you reassemble the two screws screw into the cover on the other side of the bearing. Then just put everything back in reverse order of taking it off.
Lower fan, lower fan cover, upper fan, upper fan cover, the three screws and the small nuts that hold the covers in place.

Hope that helps.

Hi Jon, the model XXX motor has a 3 hold mounting bracket a model L has a 4 hole bracket. A motor from a Model G, AF, AE will fit. If you want to send me the motor I can replace the upper and lower bearings for $35.00 plus shipping, that includes cleaning the fans, reseating the carbon brushes, it will work like new. Or if you want to have some fun and make your model XXX into a powerful cleaning machine for $85.00 I can make you a hi performance motor which will have as much suction as a Miele vacuum, it is a direct replacement motor, it will take you 20 minutes to install.

Thank You

For the replies so far…this is helpful…I think I may try to lubricate the bearings first as I have done a fan replacement on a model S so am familiar with the disassembly and reassembly process. But my question is….what is the proper type of grease to lubricate the bearing with? And where exactly on the bearing am I adding it? Into the place where the motor shaft slides into it? I don’t want to ruin anything in this process.


Speaking of the model S…I think it’s bearings or armature are having issues as well…it runs but at time slows to half power and doesn’t sound good but then ramps back up again. It may be the bearings seizing. It is old, my Grandmother bought it new in the late 50s and gave it to my Mom when she got married in 1960…then it served her until 1973 when she bought a model L to have a power nozzle and the model S became the basement vac and still serves as that today. I love the machine and how lightweight it is, I believe it’s about the lightest of all the Electrolux models that use the C style bag and it also has a cloth bag.

After decades, the carbon brushes become stuck in the shunts and the spring doesn't move the brush out to the commutator correctly. Simply remove the carbon brush from the holder and clean the shunt with a q-tip dipped in alcohol. Get all the carbon dust from the shunt. That's what's wrong with your model S. At the same time, grease the front bearing.

When you replace the motor brushes, be sure to use a commutator seating stone to seat the brushes back as well as clean the commutator. It only takes a moment holding the seating stone against the rotating commutator. Cleans and brightens it back up.

As far as the bearings, you add grease to the balls. Remove the bearing 'shield' for access to the balls of the bearing race. Some bearings have metal caps on both sides, which means you cannot grease the bearing. New bearings are still available if you find yourself with bearings that have metal shields. New bearings have vinyl shields which come off be prying at the edge with the tip of a razor knife. High Temp bearing grease, like for automobile wheel bearings is obtainable at an auto parts store in a pound can for a small amount of money.

More on the model S

I just remembered, the motor also does a huge vibration thing when it is winding down upon shutting it off. I’ve checked to make sure the motor is tight and it is. Not sure what that’s all about. Any ideas?

Sounds like the brushes are having issues for sure and the bearings too. I’m usually only at a moms a limited time so having time to fuss with the S is very limited. I live far away, too far to drive (3 day trip) so bringing the machine to my house to work on it incrementally isn’t an option unfortunately.

Hmm. Good options here from everyone including options to not have to do it myself for a reasonable price which may be the way I should go.

I also have a So era do with similar motor issues that started last August. I stopped using it immediately upon the issues so as not to do harm.
