Hello i have a hoover decade 80 that i bought from kirbycollector when i got it it had a broken fan so i replaced the fan after watching a youtube video on how to access the fan. So after i replaced the fan i put a new belt on and it worked great it just roared and growled so i figured that could of been a bearing problem in the brush so i ran it one day without the brush and took a listen and it sounded like a normal vacuum sound. After i put the brush and belt back on i smelt something bad like lead electric smell and i figured something else was wrong and i didn't see any sparks or smoke coming out. I Figured my carbon brushes were worn out so i replaced my carbon brushes and that didn't solve my problem it still smelt bad so i replaced the armature after i replaced the armature i still can't get it to work right. when i turn the vacuum it just buzzes. can anyone tell me if i buy another decade 80 if i can do a motor swap from the other machine to my machine? Thank You.

Check your upper and lower bearings and lubricate if necessary. If you replaced the armature, you could either have a defective coil/field or the carbon brushes need to be seated in with a stone. Just make sure that you do it without the belt off. If your machine had a bad smell, it could be the ozone coming off of the brushes. One other thing, check that your brushroll spins freely.

Also,

 If you put in a new fan, make sure you placed all the washers in their correct locations. Here is a video below to show what I'm talking about.

Slow down. Don't go too far down the rabbit hole. The old armature may have been perfectly fine. It's possible the new armature is the wrong one, or the bearings are seized up.

In fact, the growling noise you heard originally was likely bad bearings to begin with. The most common source of a growling noise.

I'm hoping you still have the original armature. Put the old one back and see what happens, let's start there. Pics would also help.

Check that the upper bushing is properly seated. While rotating the motor by hand tap the bushing with a rubber mallet.

First of all after i replaced the fan i put all the parts on correctly. After i got it back together and tried it out thats when i turned it on and heard the loud growling noise so i knew right away it was my brush roll.

Second. I ordered a new brush roll and belts so the 2nd time i turned the vacuum without the brush roll in i let it run for a minute and i smelled a lead and electric smell and that's when i thought my carbon brushes were bad so i replaced my carbon brushes but that did not solve my problem.

Third. I again turned my vacuum on after i put the carbon brushes in and it turned on but it sounded weak and still smelt like burning electric and lead and that's when i figured my armature might have been bad so i ordered a new armature and put that in and got it all back together and started it up and nothing came on it made a buzzing noise so here i am now still trying to diagnose the problem.

I will post pics later.

I went through something very similar with my Decade 80. I picked it up off the curb, and the fan was broken, I replaced the fan, while I had it apart I cleaned the armature, and rubbed the brushes on some notebook paper until I got them fairly clean, I oiled the bearings, I oiled the brush roll bearings and put a new Hoover belt on the brush roll, and the vacuum ran great but growled like crazy, I was thinking the motor bearings were bad in my vacuum too. I went nuts trying to diagnose it, I even had a professional replace the bearings in the brush roll, I tried different belts, different base plates. It still made noise, eventually I decided to try using it and ignoring the noise and after about 5 minutes of use the belt broke. Then someone recommended a company that sells wooden brush rolls I installed one and the vacuum now works perfectly... I think if you put the vacuum back the way it was when you got it and just change the brush roll it will run perfectly.

New brushes need run time to get broken in. The motor will sound weak and make a slight burning/arcing/ozone smell during that time.

I going to calmly say this cause because either ya'll don't understand or i don't understand.

I took it apart and fixed the fan and put it back together i plugged it in and ran it the brush roll growled.

The next time i plugged it in i took the brush roll completely out and the bottom plate back on i set it back upright and turned it on and it sounded normal but i started smelling burning lead and electric.

So i replaced the carbon brushes i turned it on it sounded weak and still smelt burning lead and electric.

Next i replaced the armature once i put the armature on i got it back together i turned it on and it didn't turn on it buzzed.

So i may not have done something right. I might not have put the armature on right.

I did look at hoover decade 80 schematics to look for the armature and i got the right one.

Typically, if you hear a motor buzz when powered, but with no movement, it means electrically it's ok. The armature is probably just stuck, and cannot turn. Try rotating it by hand?
