$10 'Dirty Kirby' G3

Back together...

The hot, dry shed turned out to be just the place to get that bag dry out. The sun finally came out a little after noon and I went out to the shed, fully expecting to have to set the bag out in the sun but there was no need; it was bone dry, except for a tiny bit of almost black water in the emptor, which I was able to wipe out with a paper towel.

Once I got everything back together, I let the vacuum run for a minute or so without a filter bag and the fill tube hanging out, just to blow out any more water that might remain, but there was none.

The bag looks about as good as I could expect, given its age. There is some minor discoloration, which is most obvious down near the bottom, where it stayed folded up and protected from light (see second photo). The rest of the bag has a very slightly pinkish caste to it. Other than that, just some minor wear. I've seen worse on newer machines, so I'm not complaining.

The next part of the project will be to polish the metal but I'll need cooler weather to tackle that. I've also noticed the rubber 'tires' on the rear wheels are wearing kind of thin. I've got another set on a spare Tech Drive that may find their way onto the machine later on, probably after the polishing.

The funny thing is in the three weeks I've had this G3, I've been far more obsessed with fixing it up than I've been with the Sentria I bought last spring, which has been sitting untouched in the barn for almost five months. All it really needs is a good polishing, which would be an easy afternoon's work. The now not-so-dirty G3 is at the same point, more or less, but my gut tells me it will require a bit more elbow grease to put a shine on it. Right now, the G3 is sitting out on the deck I'm considering whether to bring in for a test run or just carry it back to the barn to continue slumbering and waiting for a crisp, fall day—or at least one that's not so dang muggy.

I just gave the G3 a little test drive on the Persian rug in the dining room. It performed pretty much as I expected it would. The Tech Drive doesn't feel as powerful as it does on my later machines but seems to kick in a little stronger pulling it back than pushing it forward. Not sure what's up with that. Perhaps it has to do with the worn rear wheels. Maybe I need to do a wheel swap sooner rather than later. The height adjustment is also not as smooth as it should be. I'll give it a dab of grease and see if that helps. All in all, this little project is coming along.
 
Stuck in REVERSE!!!

So I swapped the new wheels onto the G3 and they get a whole lot better traction than the old ones but there's just one little problem. The Tech Drive transmission is stuck in REVERSE! It's also quite powerful so I'm totally fighting the thing when I try to push it forward. I guess a tear-down is in its near future but I'm not exactly sure what I'll find or how to fix it when I do that. I have an extra Tech Drive unit from a newer Kirby. Perhaps I should just swap that in and see if it works any better.

Swap out the tech drive and see if you can keep reverse and drive switches. You always notice them I'd there incorrect.
The bag looks like it's in good shape too.
 
Tech Drive is fixed!

I just fixed the Tech Drive and I didn't even have to remove it; in fact, just replacing it would not have solved the problem. I watched the YouTube video linked below and it was 37 minutes well spent. Although I did not follow the video tutorial to the letter, it gave me a better idea of what to look for once I got it opened up and to formulate a plan to fix it.

I took the cover off and the inside was just furry and gross so I took it out to my shed, where my air compressor lives, and thoroughly blew it out, which was an oddly satisfying experience, even though I decided to wear a mask to do it. Once I could see the mechanism under all that gunk, I realized the sliding direction control block, located just forward of where the handle connects, was frozen up. So, based on knowledge gained from watching that video, I employed a time-honored caveman strategy and gave it a couple of light taps with a hammer to break it free, then sprayed it liberally with silicone until it was moving back and forth smoothly and easily.

Once I was satisfied I had it moving like it should, I brought the motor unit back inside, put the cover back in place without screwing it down, reattached the nozzle and bag so it would run, and gave it a quick test drive. It now goes forward and backward just fine. It's not jerky as some have described the G3 transmissions but it's definitely more aggressive than its counterpart in other models I own. The last step will be to shine up the aluminum to make it look somewhat close to as good as it now runs.

 
Transmission Handle cleaning and adjustment

Hi Edgar!

I just worked on a G3 handle transmission assembly. I would be glad to share what I did if you're interested. Mine came out perfectly and works better than brand new. It's not as hard as some make it out to be.
 
Lou,

I'd be interested to know what you did. I feel like I've got the G3 working reasonably well but there's always room to learn more. I haven't had time to mess with the G3 lately as I've been focusing my energies on a Classic III I just acquired.
 
You don't show one in your profile.

I don't have an upgraded membership so I can't delete posts. But if you do, you can add it to your profile and then go back and delete it. OR, we can ask Robert to email person B person A's email address.
 
Started polishing...

So I began the polishing process today with the handle and the nozzle. The handle came out great and the nozzle came out okay but it could probably use a bit more attention. One thing's for sure. There's now a marked contrast between the nozzle and the rest of the machine, which shows its potential.

I had to stop because the shady spot, where I was working in the back yard, went away and it got too hot to be out there. I'll just have to wait for the next convergence of comfortable weather and free time so I can continue the project. I don't think this machine is ever going to be a showpiece but I'm pretty sure I can get it looking decent. I haven't decided whether I'm going to keep it or donate it to my church's rummage sale next year. If I decide to keep it, I'll most likely spring for a replacement fan kit. If not, I'll just let it go with what it's got. But I've got a year to play with it and make my decision.

I'll post some 'after' photos once I get the polishing done to where I'm happy with it.
 
Edgar.....

Keep up the good work! I really enjoy reading about your progress and process.

I can relate to jumping on a new vacuum before finishing the one right before it. Like now, I grabbed one of my Traditions and put it up on the work bench when I should continue working on the Atlas.

After reading the info. on polishing with Mother's in a different way, I will now HAVE to redo my Kirbies.

Cheers!
 
'Dirty Kirby' no more...

So I took advantage of cooler weather today, tore down the 'Dirty Kirby' and gave her a polishing. It is by no means perfect but it's a helluva lot better than it was. It's no longer the derelict looking machine it was when I first spotted it at Goodwill. One thing's for certain. The G3 is a lot more trouble to take a part and reassemble than its later siblings. Simplification of the design in later models was definitely effort well spent on the part of Kirby's engineers.
