I got this given to me...I wonder why :-)
After a quick look I reckon a few days to get this back up to a nice shiny Kirby.
Nothing appears to be seized but at this stage dare not switch it on until I have a closer look.
I will post more images as I progress.

I'd change carbon brushes. They are cheap and easy to change being you got vacuum this far. I'd say try SOS scrub pads will get a good majority of the oxidation.

That will be Brillo pads in the UK, I have used them on various projects over the years.

Wow, this will be a labor of love

Was the machine partially submerged for a while,like a flooded basement? How do you think the transmission will be, I guess it is sealed up pretty good against water seeping in.

Apparently it was stored in a garden shed for a few years. The slide for the transmission moves freely so I reckon it will be ok.
The image below shows the innards and they are not too bad except for a few cobwebs, not much evidence of corrosion.
With what I scraped of from the inside of the fan enclosure and the nozzle head I reckon the last job it done was vacuum something that was wet as that's where the bulk of the corrosion is.

A flooded garden shed, I reckon. I wouldn't count on the transmission being totally free of water intrusion. Water always finds a way in.

Me, personally, I wouldn't even bother trying to remove all that corrosion by hand. Much easier with a wire brush wheel on a drill, and a smaller one on a dremel for the hard to reach areas.

With brillo pads I wouldn't say a labor of love once you start in with brillo pads it cleans up quite easily. G series aluminum is easier to clean. A dirty g series are alot easier to clean than pre g series vacuums.
Like I said carbon brushes and if you go to Amazon or eBay they have an led light for a few bucks looks pretty cool.

Looks more like a GSix with that black trim, or is is just so nasty that it looks black? Anyway, I'm glad this sorry soul found it's way into the hands of a loving collector!

It is a G5, getting all the rough crap of it now, nothing seized and considering all the crap that came out of the fan housing the other internals dont look too bad.
I used a wire brush on my bench grinder to get the rough off the inside of fan housing and will smooth it off with steel wool and/or wet & dry.

You are very mechanically inclined and it looks like it will be a polished champ. Just please tell me your installing new carbon brushes?

Kirby transmissions are not at all water tight. The half of the housing which faces toward the N/D pedal has several large openings for the clutch engagement arm to make contact with the clutches, for example.

That said, I don't foresee much inside the transmission being affected by water. The rear axle could rust (it is steel, unlike the transmission housing halves, which are aluminum), but it is external to the transmission and separately replaceable. Water could have intruded into the needle bearing which supports the transmission input shaft and spoil its grease, but that bearing is obviously up at the top of the transmission. The vacuum would have to be sitting in inches of water in order for it to be affected.

Lesinutah............"Just please tell me your installing new carbon brushes?"....

Yes I can get a set for around £4, You do seem quite insistent that they get replaced, whats your reason? I ask because my electrical tools drills etc I would only ever replace when necessary and not as a matter of course.

I have a G5 that was almost that bad when I got it. Barkeeper's Friend, a very mildly abrasive scouring powder, made quick work of the oxidation without adding extra scratches. Automotive rubbing compound (the reddish stuff), followed by Mother's aluminum polish and a coat of car wax to seal the metal brought it back to a satin sheen, not quite mirrorlike, but very nice. It's been a few years since I did it and it could use a follow-up polishing. What I did was all by hand but I now have a Mother's Power Ball polisher for my drill, so I'll use that whenever I decide to give it another go and see if I can't bring out an even better shine.

Wow - that thing was in BAD shape, but looking better as you go! For free it is worth a shot. Looking forward to seeing how the polishing goes. I am working on a Classic III that is pretty bad cosmetically, but nothing like yours. I like to see a challenge!
If you get it running well and plan to use it a bit, do replace the motor bearings since they could be corroded internally or grease dried despite being sealed. The carbon brushes are 3/4" long new, so I replace them when they get to 3/8" or shorter (or are damaged). Do mark them so you know how they went in should you choose to reuse them.
Keep us posted with the progress!

Replace the brushes now while you have it open, so you don't have to do it again later on. That's what Les is trying to say.

Because as you seen with this Kirby, you never know what a vacuum has been put through by the previous owner, and more often than not (at least in the USA) vacuums are run into the ground and then some before they are donated or trashed. Better to replace everything now while it is all laid out than to keep opening it up repeatedly every few months (you can actually strip out the threads in the screw posts on plastic bodied vacuums by unscrewing the screws too often).

It's just like when you buy a used car, you replace every high-wear rubber part (tires, hoses, belts, wipers, door seals) before you drive it, because good chance the previous owner didn't do it and they are pretty worn by the time they sell it off. You wouldn't want a radiator hose to blow or a belt to snap when you're going down the freeway doing 75/80, that would be a pretty bad time!

Same with a vacuum, you don't want to do all this hard polishing work and all the time of taking it apart and cleaning rust off, and then have the motor die just a few months from now.

I try to get my vacuums to factory-fresh condition when I clean mine up, and replace anything that looks significantly worn. The carbon brushes get replaced along with the armature getting polished to remove carbon buildup. It helps get the motor's torque back and make the motor perform a little stronger, especially if the vacuum was severely abused. Running a worn vacuum motor will further wear it and eventually irreparably damage it, if not burn it up.

I too have a Kirby G5 that's been in a worse state that I hope to get repaired this summer. It looks worse than it is, a lot of it is just dirt.

Some updated images to show some progress. I dont think I will hold on to this one but sell it on as the paintwork is peeling on some parts of the lower case where there was corrosion and I cant renovate that.

I have put most of the shell back together temporarily but that was mainly to check it was actually working as I didn't want to spend another few hours on it if it was a `no go`, Tech drive and handle slide all working fine, a new LED bulb in it.

I am using the coarsest buff wheel at this stage and still having difficulty getting some markings off the casings, but making progress. It is not so much scratches the surface is actually quite smooth but a `mottling` that seems to go beneath the surface.

I think I am going to struggle with the belt lifter though as it is well rusted but still operates, I may just do the best I can with a dremel and wire brush but would like to clean out between the washers. I would like to get that off but cant source labels in the Uk.

My first Kirby was a g4. I took apart and had no idea what was wrong. It just grinded and sounded bad. The carbon brushes we're gone. I recently got a model c Kirby. It's carbon brushes we're gone. Looking at the vacuum I doubt they changed them. Just for piece of mind changing them while it's easily to access could save huge problems.
You said you didn't turn vacuum on yet. You want to make sure everything is done right. This would be one thing to check.
I have 3 sentrias and 2 g6s and I ordered carbon brushes for all 5. I'm opening them up just like you and it will help vacuum run in peak condition.
Sorry to be persistent just don't want you to finish vacuum and have to test apart put carbon brushes on.
Les

I managed to ease off part of the label and get the belt lifter off, what a state, now much cleaner.
Its a pity about the plastics and paintwork otherwise it could turn out to be a tidy machine.
The outer casing looks shinier than it really is as I still have some light mottling which appears just under the surface, buffed most of it out but considering the rest of the cosmetics will leave it at that.

You can buy plastics either get a parts machine or buy from kirbyneeds. If that's an option.

Lesinutah......by the time I buy the plastics I would still have the damaged `paintwork` so just going to sell it on and use the cash to buy a better model.
The attached image is as far as I will take this one, you can see on the image some of the `mottling` on the aluminium.

It would take a lot more work to sand out the mottling and the scratches.

Its still a vast improvement from when I got it. It has been a good learning curve for me with the carbon brushes, the belt lifter and the brush roller, so not in vain.
