Another brilliant video TPAI! The oil you’re meant to put in the air filter is probably to make the metal filter-gauze sticky enough to trap particles and thus take them out of the air breathed by the motor. Road vehicles (and others) used such filters in the 1960s and 70s, along with “oil-bath filters” on some - usually heavier - vehicles. I enjoy all your stuff, always fascinating. Les in UK

Yes, the oil bath filters were used by all auto manufacturers back in the early days of motoring. They transitioned to the common accordion style paper filters around 1950, best I recall. Not so many dirt roads, no need to filter out the big chunks anymore. 🤣👍

Genial....! Mega! Ich liebe Generatoren und deren Technik! Coole Folge! 👌👍 Grüße aus dem Saarland...

I love your intros. And I love a stubborn Gerolf...

Your intro is a brilliant and insightful synopsis of the human condition... history blames the leaders, but individuals shape the carnage. Up to the 80's VolksWagens had oil based air filters... better than anything else... needed no cleaning or replacement for 10's of years.

As always an amazing video. Fun fact: back home in Portugal there was a factory building SACHS motorcycles licensed by SACHS and there is a huge cult around them with clubs and etc that do events. Really cool brand

Excellent intro. Fully agree. Power generation is one of those basic needs in life. Joy to watch...

I'll bet those 2 stroke engines smell so damn good while running. I used to have a 2 stroke dirt bike and the smell always brings back memories 😊

I like the cap for the exhaust, it keeps critters from moving into the motor and fouling it. It shows someone was really thinking about the kind of things that could go wrong.

What a struggle to get that generator working! Respect for not giving up on it. I barely understood anything of the electric diagram since electronics isn't my strongest field, but seeing your reaction when it sparked to life again was wholesome! Also, what just came to mind, have you ever looked into teaching? Since you really like making videos about the process and showing people what you learned and how you did it is already up your alley

Dear Brad Crossman. The first time I heard about the brand was as a child. But in a very different context. The very famous "Fichtel und Sachs Dreigang- Nabe" respectively "3- Gang Schaltung mit Freilauf" was on nearly every common bicycle produced in the 1960/70/80's. At least in Germany. Please kindly allow me to suggest that you google it yourself if you want to see/learn more. 2) I watch a ton of utube videos. Some of my favourite channels are from Canada. Best regards, luck and health.

Another excellent video! A note on oiling of the filter. It's not for preventing corrosion, it's to allow the filter to catch small particles as they stick to the oil inside the filter. Older VW beetles in the US had oil-bath filters which worked on that principle. They were simply a box with steel wool inside that was coated in oil.

I love your step-by-step diagramming that shows a circuit evolving. You are the only place I ever understand circuit diagrams from without tremendous effort. I think technical people often explain things as if they're showing a peer that they understand it, rather than are teaching someone who has never understood it. Like, yes, those explanations are good, if you didn't need them in the first place. The difference is context. You give context as to why changes are made, and how they take effect. Well done. 150s hours? Oh my.

Nothing is ever easy. You got that. Thanks! This is great. I think you "flashed" the field in the AC generator. My guess is the remnant flux in the field had diminished to near zero and it wouldn't start generating enough voltage to do anything. Fifty years on the shelf will do that. These are good videos and the editing is outstanding. I've been fixing electric "fireplaces" recently. Hardest part is making a schematic and usually you figure out what is wrong while you are doing that. Keep on keepin' on! :)🙂

I appreciate how tenacious you are, and your thoughtfulness shines in the opening comments. When you stripped down the large generator to its bare minimum you really provided a clear explanation of how electricity is generated. I don't think I would have understood it if you hadn't shown the struggles in the first part. Thanks for all your efforts!

One the best channels on KZread. Lot of context and history of war gadgets. Fascinating.

those generators are loud! imagine transmiting in the radio and that racket was going on next to you

So much respect for the effort both to film and to fix. You are a machine yourself! I’ve watched your entire series many times over and I must say that you yelling “Yes Yes!! “ gave me shivers and made me so happy for you! Truly inspiring thank you :)

I love that you do show you mistakes and help us learn form it as well and help us on how to deal with it! thanks a ton for these amazing videos!

can we take a second to admire the 50cc units, german precision work of old, 25 to 1 oil ratio and no blue smoke, incredible

The air filter element on the larger generator is oiled not to prevent corrosion but to provide a sticky medium that captures dust particles. Older cars had the same technology. Very interesting video and your explanations and clarity and precision of language are appreciated!

haha the momnet you got it working and shouted YES!!! was just beautiful, good work i love this channel you get a history lesson some electronics knowledge , and some mechanical all in one just brilliant.

Just discovered your channel! Very impressive skills and as a fellow engineer, I’m glad to see you putting this out there 😊

Nice work!! On old generators without AVR (Automatic Voltage Regulator) those transformers are used to compensate the voltage drop for the current draw! I have and old Honda EG1500 and it uses a transformer like those on yours. One coil of the transformers is where the live wire enters and exits making a coil that increases the magnetic field when you draw current from the generator…this magnetic field produces ac voltage on the second coil of the transformer that is then rectified and feeds the field coil of the generator compensating for the voltage drop. When there is no current, the second coil of the transformer have 0VAC and the 230VAC is only produced by the remanent magnetic field, that passes thru a resistor and bridge rectifier.

Outstanding troubleshooting of the generator circuits. I was very impressed by your technique of simplifying the generator's circuits by eliminating all of the unnecessary and/or intermediate components. I do not understand much about circuitry but your logic is impeccable.

"And that I'm willing to admit publicly...." I've got my eye on you haha! I loved the intro man I would love to work to a common goal but I really don't see that happening in my lifetime. If it was possible to settle differences without combat that would be great. Been to Afghanistan twice as infantry and really saw the worst of human behavior. I did my best to actually help the people who lived there. Fighting an insurgency makes you paranoid of everyone which then makes them distrustful of you. I started treating them like neighbors and not potential threats and my experience changed. Made some friends I still talk to and at the time felt like I left my AO better than when I arrived. Since I've been out I solve problems without violence ever considered when previously it was often my first consideration. What I'm getting at is it forced me to open up to others perspectives and improved my critical thinking. Anyways man great video I love seeing old tools getting restored and is something I do myself when I can. Often times it ends up costing the same or more than new but the knowledge and experience I gain from repairing them I cannot put a price on.

Your hard work and passion is great to watch, thank you for another very enjoyable video.

Thank you for explaining remanence, which led to finding the term retentivity. Your videos are wonderful and encouraging!

19:19 "just figuring out how to disassemble something like this can take forever" i feel like this fact gets no where near the attention or recognition it deserves. making sure you can disassemble something without causing damage, in addition to disassembling that thing in such a way so that you know how to put it back together, are often some of the most time-consuming aspects of a project like this. thank you for giving lip service to these concepts.

You are very smart and methodical repair man. Job well done on everything in this video. Especially the big generator repair. Also very glad you put emphasis on how all these dirty jobs are not easy and fast. I know how doing things the right way is usually doing them the hard way.

Nice job as always and for showing how sometimes things don’t go according to plan and not giving up gets you there in the end

"Will it run..?" lolol I guess you couldn't help poke fun a bit. Your channel is awesome.

You are a shining star here on KZread. Thanks for all you do.

I think what I like so much about your work is how it differs from everyone else's. You seldom just restore old equipment to like new or just repair to good working order In the spirit of the post apocalyptic inventor you have no hesitancy to discard old functions and modify parts to get good use out of the castoff things you find. The intelligent improvising is inspiring. It is what we all wait to see in your videos. and seeing you actually use the things you make from the stiff you find to work on the latest find is best part.

I could feel it, the true joy of it finally starting and making power.
