Can any of our Lux gurus here tell me the magic formula for getting inside an Electrolux PN-4 power nozzle? I'm very familiar with PN-1s, PN-2s, and PN-5s, since I have owned all those for a long time.

But the PN-4 has no visible screws other than the two for its chrome soleplate. What gives?

I had a PN4A and remember having to lightly pry the sections apart after removing the two metal plate screws. Wish I had one in front of me to help right now. If you can get the chrome sole plate off a PN2 you can do anything. I attached a cool link anyway :)

Thanks for the link - I'll try the pry.

By the way, folks - the new machine has a name now.

She's Goldielux. :)

Pic of a PN2 I restored might help too :)

I remember having to figure out how to get the top and bottom separated on the PN2 as well as the PN4 and the two screws were all securing tightly together. The rest was all axles and dirt that had fused it together. I would take the precaution of removing the screws from the underside and top of the wheel assembly on the PN4. Wish I had saved the pics now.

Electrolux-Dude to the rescue!

Hi Sandy, it's Nathan here. Loosen the 2 long screws on the bottom plate, lift it off, and then the top cover will lift off, and after you have the top cover off you will have access to the inside of the power nozzle, motor unit, brushroll, etc.
Hope this helps!

Nathan! Still have all the machines you've placed with me for adoption!

Thanks for the info.

Thanks, Nathan!

The PN-4 has now been disassembled, all parts cleaned or washed, the bearings lubed and the unit reassembled.

It was the nastiest PN I've ever seen - impacted with solid globs of dog hair and dust and spider web. It appeared as if the mess had been wet or in a damp basement; it was like cement.

Works like new now, and smells like it should - which is to say it does not smell of anything at all.

Thanks for the advice!

P.S.: Interesting to see how the PN-4 had been simplified and improved over the PN-2 - there are fewer parts, and they go together more easily.

Forgot to mention - another member here gave me a tip a long time ago I've never forgotten, which helped with this PN.

If the brushroll seems to be in bad shape, try washing it before you spend the money on a replacement. Hot soapy water is like Viagra for brushroll bristles!

Saved about $20 - PN works great now.

Ya'all inspired me to take apart my old (original purchase 9/1984!) PN-4A power nozzle which has been making a terrible racket! You will no doubt laugh, but I used a tweezer, feather, used toothbrush and rag to clean all around the motor. Yup--not a guy! I also put on a new belt--I think the one on it was not correct--too narrow and walking around maybe?

Anyway it sounds like new!

I will be browsing around to look for answers on some other questions about the hose and tightening the access door to the bag.

Thanks for inspiring me and letting me know this vintage machine (Silverado Deluxe) is worth working on!

Sounds like you did a great job cleaning and servicing your PN4A. The Silverado is simply the best !

PN2 vs. PN4A (good and bad)

human's profile picture
I've had a PN2 for a while and just recently acquired a PN4A. They're quite comparable to one another in terms of performance and design, the PN4A being a simplified version of its predecessor. Comparing the two, there are some things that are improved and some things not so much. It's great that the PN4A has a permanently attached cord. There's really no reason for it to be removable as it is on the PN2. Mine doesn't have the retainer clip and does come out from time to time, mainly when I'm wrestling it in or out of the closet. On the other hand, it's unfortunate that they did away with the inner motor cover. When I opened up my PN2 the first time, and took that cover off, the motor was amazingly clean. By comparison, the PN4A's motor was heavily caked with dust and dirt. I've already ranted about the PN4A's scratched up paint, so I won't belabor that point further.

Great point human

My PN4A motor was also caked in dirt. I think the motor cover was a good idea as well. I remember getting a nasty shock from a PN4 that was visibly arcing as a kid. Maybe Electrolux figured since the PN4 had a painted cover that the added protection was no longer needed. But then my PN1 with the plastic cover also has a motor cover. Or just production cost saving.
