I have this Super J that I've had for a few years that I've finally gotten around to tearing into since the motor wasn't running right and found the armature is pitted and severely discolored. I was wanting to know my options on a motor replacement since I cleaned it up and the motor seems to only be turning at half speed and is sparking a lot. I have a motor out of a 2100 but I don't know if it would be too much for the wiring in the Super J. I vaguely remember that there is a mounting plate to install a Ametek motor for these, but I could be mistaken. I'm wondering if that would be a solid option or if I should track down another Super J motor. I plan on paring this machine with a newer L shaped PN and a non woven hose so the machine not being original isn't a concern for me. I do have a PN-4 but I have that paired with my Model L, but I can flip it over to the Super J and run the PN-6 from my old 2100 with the Model L instead. I was just wondering if it would be worth the trouble of seeing if that 2100 motor would work in my Super J or put in a Ametek replacement since the 2100 didn't survive the move to my current house and would like to use what parts I can to fix some of my other machines if possible.

The best thing you can do is to obtain a new Super J armature. I see them on Ebay all the time. About $50. You don't have to change or modify anything, nor do you have to rig anything like you would trying to fit that 2100 motor into an SJ.

SJs were notorious for armature failure. If you can get a new armature, that would be the best solution without having to do a motor replacement. The 2100 and later would not fit in the SJ I think.

I have the field assembly and armature from an early Silverado motor that you may have for the cost of shipping. They were removed from a motor that I tested before disassembling it. It ran at the proper speed with normal, minimal sparking and drew the right amount of current. I was starting to stockpile these parts to keep my Silverado running for decades, but I decided that one spare motor is enough.
In the image you can see from the rust that the motor ingested water at some point, but not enough to harm it. The windings look fine, and as I wrote above, the motor ran fine when tested.
Please email me at the address in my profile if you're interested. If you don't want/need the field assembly, that's fine, and it will reduce the shipping cost.
A nice guy on the Facebook Electrolux vacuum USA group Charlie Calcasola rebuilds the motors for around $35 (don’t quote me) and you pay shipping to and from him. I have a Silverado and the motor has issues and am considering having him rebuild it because the motor has never seen water or other corrosion so is a good candidate.
Brian Satterwhite at RVAvacuums.com an Aerus branch in Virginia does restorations so you may also consider him as another source.
The Super J through Silverado series really had the best motors in them.
I wouldn’t be as quick to go the Ametek replacement motor route. They just aren’t the original nor as good quality for the money and I think a quality rebuild would likely last another 40 plus years.
Comes to the Rescue!
