OK, i need a few bearings tutorials.
1)Kirby DS50/80- I love my sanitronics and cant wait to use them, but the bearings are terrible. Ist there any other tool i can use besides a special "bearing puller" that i can use?
2) Brushroll bearings in a hoover DAM/Convertible- Ive heard this is a quick fix. Can i grease them, or do i have to replace them?
3) Brushroll bearings in 1996 panasonic performance plus.

Thanks,

VW
 
Kirby Bearings

Vac_whisperer, I am sorry to say that the only way to remove the rear bearings from a Kirby armature IS to use the Bearing Puller. Any other attempt may damage the armature. They may be a little costly, but you will save trouble and prevent damage by investing in one.
FYI- When you are ready to put new or repacked rear bearings back onto a Kirby's armature I have found that if you cover the opposite (fan) end of the armature with an old belt you won't damage the threads that the drive shaft screws onto. AKA- pad the threaded end when hammering the rear bearing back on.

Proper refurbishment of bearings is fairly easy, so long as they're not too badly worn down (in which case it's easier just to buy new ones)... :)

For Ball bearings, you need to clean them out in a solvent first to get rid of dirt and old grease, simply remove the seal (if not an open bearing), wipe them clean, then place the bearings into the solvent and using a pencil or screwdriver rotate the bearing to work the stuff in, then allow to dry (24hrs at best). Then apply the grease with a flat screwdriver or a putty knife and then replace the seals and refit...

Bronze sleeve bearings are easy, just use cotton bud sticks (or cue-tips, whatever you call them), soak them in oil and wipe the inner race out until the cotton comes out clean, then soak in oil (most will have a wadding to hold oil, fill the bearing until it won't absorb any more oil), then refit... :)

Now Hoover brushroll bearings are interesting, they have a small circlip holding the two halves together, you need to get this out which is a bit fiddly, but once you get it out, you can separate the two halves, be careful not to lose the balls though. Clean them as per ball bearings above, apply grease and stick the balls into the grease then reassemble... :)
 
Bearing grease for ball bearings, 3-in-one oil for Bronze sleeve bearings, both available pretty much anywhere that deals with mechanical stuff...
 
Justin- I love the idea of a belt around the fan!

If any of you get your supplies from a vacuum supplier- Buckeye sells a nice bearing grease.
 
(VW) & Kirby bearing puller...

Hello ??? (VW).

The Kirby rear bearing puller is only $17.00.

It makes removal so simple & it'll pay for itself if you use it a couple of times. Someone at a shop would (probably) charge you more than that in labor to do it for you.

If you decide you'd like one, just let me know. My contact info is in my profile.

Cheers & hagd all,

Bill
 
Are there any recommendations for what type of grease to use in Aerus/Electrolux bearings? Does it make any difference according to era (Model XXX/Model LX/Model LXI; Model 1205/Model 1205J/Model 1401/Model 1401-B/Model 1505; et cetera)? Also, I understand that some Aerus/Electrolux motors have one bearing and one bushing instead of two bearings. With what should the bushings be lubricated?

Regarding sealed bearings I happened to discover this Youtube video:

 
The

bearings that go into the early Electrolux models are 7mm and 9mm , and the newer Electrolux and Aerus bearings are 8mm. When I was starting out the bearings were open on two sides. Then grease of choice was Lubrico brand . Later the bearings came out with sealed bearings . It was not uncommon to refer to them as 37kdd,38kdd, 39kdd. The other bearing used on Electrolux were Sleeve bearings. The older ones do wear out and require replacing.
 
If

the E has a motor with 2ball bearings the small one is 7 mm and the large one is 9. If your motor has a sleeve bearing the ball bearing is an 8 mm. Part numbers depend on where you buy. What you need is asset of carbon brushes that will fit the XXX, LX, E, AE, AF and early G.
