- In this video we revisit the 1945 Onan W2S and get the governor adjusted correctly.
Please watch the previous two videos concerning this generator;
Part 1: • Lets Get This 1945 ONA...
Part 2: • Lets Get This 1945 ONA...
1k overload . That is impressive. I know most people like the new stuff . But that is a real generator. Love it
Your explanation of the govenor function was good. I watch this channel because of your explanations!
Should be a instructor at tech school. Very clear consice English speaker
I'm about the age of that generator, and I wish I ran half as well as it does.
Just love the sound of those old low rpm generators just a nice humm something you could go to sleep to!
I know what you mean.I had a5000 watt running for over 3 days last fall.After the 2nd night it doesn,t annoy me.3,600rpm. The old ones turning half the revs does sound nice.
That thing puts most modern day generators to shame. Nothing at all wrong with analogue power generation. Well done, sir.
Your ability to find these old machines boggles my mind almost as much as your knowledge of fixing them. You the man.
I agree 👍 I love his approach to every (new) project 🤩
I know it makes me want to find one too but I know I'd just electrocute myself.
Mike, this vid is a
This vid is an example of why I have for quite a while named you "The Professor" - I always learn something from you, and your explanations are clear enough, for me at least!
I wish the newer portable generator governors were that responsive. Very nice. Handles the overload with no issue at all. That is a healthy engine.
That's 1 smooth runner. You and Pops should head up to the Williams Grove show this weekend. Steam Engine and Tractor Show. Not 100% sure if the flea market will be running this coming Sunday but it's worth the trip.
I'm concerned about that long threaded stud sticking in the fan shroud from the back...
Very very very cool to see that old school generator just purring along!
Keep em coming!!!!
The sensitivity stud is stock haydenc2742, nothing to worry about. I have to say, you have good eyes though. 👍
The static governor adjustment can do wonders for the way an engine runs. I did it often on lawnmowers when I worked on them back when. I am really impressed with how well you have that adjusted, absolutely fantastic work!
That 1k overload response was impressive.. some of today's modern junk wouldn't tolerate that!
much better motor starting ability, remember this stuff [before cheap junk] would run full load for weeks
most box store generators require an oil change every 25 hours and wont last more than a few days. or even produce rated load.
There aren’t many good small generators out there these days.
Back in the day when things were made to last. That was normal back then. You probably could pull 3 or 4 k on that all day and the only thing that it would burn is gasoline. Another great video Mike
You guys are nuts. It’s overbuilt to an extreme, but that doesn’t mean today’s stuff is junk. It’s built for intermittent use, you can still get gennys this Heavy Duty, but not at Home Depot for $500. You’re comparing apples and oranges. New stuff isn’t all bad, but I guess if you guys buy stuff at Lowe’s and Walmart then you deserve what you get.
Its funny how much they put into the look and style on all the old stuff, now you just get an ugly box :( Nice old machine, piece of art!
what a beast. It's super quiet too, like a Honda inverter
I run my mate to this with a smallish auto muffler and then it’s really quiet.
Nice little unit. They really knew how build things to last back then.
On that design when you change the sensitivity adjustment you're changing the leverage that the governor external spring pulls on the governor arm the closer to the pivot point the easier the governor can pull against the Spring the farther out from the pivot point the harder it is to act on the external govenor spting.
It's basically a lever and you're changing the pivot / balance point.
That's how I was instructed on how the mechanical governor external adjustment works.
Very nice improvement! The overload capacity is very impressive, too. As with most of the machinery from that era, it is very well built.
Understand about working on modern units with Woodward systems and PLC control; and going to a full mechanical unit. At first it seems very imprecise but you have to understand that the loads they powered with this weren't really affected by small frequency deviations. So it was very much adequate!
For being over 70 years old, that's damn good as far as I'm concerned.
I always find it interesting how well calibrated mechanical controls can do in comparison to newer digital controls.
As for governor to throttle shaft play I usually add a light spring between the governor arm and throttle plate separate from the governor linkage to hold compression on governor linkage itself.
Tecumseh engines use a similar trick utilising a torsion spring between the carb body and throttle plate opposing the governor spring tension holding some compression on the governor rod.
It would seem that the engine is way bigger than the generator head it's attached to requires. That's probably partly the reason why it's so good because it's not running at its limits all the time. Also, Look at the beautiful design of that radiator shroud/grill. They didn't have to make it fancy but they did. Have to love machinery from a time when companies took real pride in their work instead of trying to eek each cent of profit out of something.
Nice fix on the governor, I might have used a grommet type inset and use the same pin..the idea that the grommet would take up the slack.....but still a nifty fix....John
I have one of these (a Montgomery-Ward/Onan W2C) that my Dad bought new near the end of WWII, and it runs equally as well as yours! It is my favorite piece of antique equipment! Thanks for the W2C videos!
Mike, you fixed it better than Factory, your ability to figure out the problem and fix it amazes me. A friend of mine has the possibility to get that exact same machine. If it happens, I'll follow all your guidelines to make it work like yours does. I'm sure as well as you fixed your machine there, it is not for sale. If I were you I sure would not sell it
Your invested time in explainning how the govorner system works was not wasted. Your want to pass on the knolage of mechanics pre electronics running life is apariciated. Thank for your time sir.
Modern generators and some higher end engine applications use a spring between the throttle and the governor arm, effectively in parallel, to eliminate the play in the linkage you showed. Keep up the good work! Love this old stuff.
Most of the small governed engines I worked on featured tension springs installed alongside push/pull rods to remove the backlash.
Very well done. Congratulations on sleuthing the governor issue out and the clear explanation of how it works. Now that it works as well as it looks makes it a special addition to your collection.
We have 2 Onan gensets, the w3s we run every year, the other one is a w2s That has sat for 35-40 years without being run or turned over. I dug out the w2s and got it running and running good. Great job on the governor set up, couldn’t have explained it better myself.
They will never make a more robust workhorse like that old genset. Thanks!!
Got it running like a top, now! With a bit of care and maintenance, ready for another 76 years of service!
Hi. Thank you for uploading videos for us to enjoy. You are a natural in front of the camera explaining how things work. Will be waiting for your next installment.
Hey I’ve watched quite a few of your videos and you do an excellent job on explaining in all aspects of different jobs but in particular the governor on 1945 onan
Enjoy watching your skills, and your enjoyment of these old engines and machinery...
Ironically we’re back to a time when frequency and voltage and dirty power doesn’t matter. Pre electronic era stuff didn’t care about pure clean sine waves, then electronics came out that couldn’t handle any deviation, and now most electronics can run on 50-60hz and 100-250 volts since they run on low voltage DC power and have transformers.
Excellent update, explanation was fine and the outcome for your effort was great.......... I love all your vids none are too short or tooo long, I enjoy the long vids more.
Nice, this Onan found a good place for a little R&R.
Sweet mschine
Bring your old generator to Mike's Generator Spa for a quick massage and tune up
That's really great response for a mechanical system! What a beautiful old machine!! Outstanding job!
GREAT....have to love the old ones.... nice to see them running good
The mechanical governors I dealt with were rated at up to 5% so what you have achieved there is very, very good! Like 1.5%!! and that linkage upgrade makes it much more stable. I figured it was linkage related from the last video, but I never would have expected that level of improvement! And on the last one, we were saying to pull the brushes and brush springs, you just couldn't hear us! lol. I just use a dressing stone when there's that sort of room to play with. It's better, imho, in that it cleans the commutator and slip rings plus seats burnt brushes, when you have burnt brushes. Mine has a fine stone on one end and a course on the other, think it's made by Ideal.
They don’t make them like they use too nice piece Mike great job on that linkage
I think you nailed it, the sensitivity spring helps with the Hysteresis of the main spring to control lag. That engine just ticks along, the don’t build them like that anymore.
Your explanation of how the governor works was good. That engine is barely even half throttle at full load. Makes me think that they offered this Engine with different generator heads. So perhaps they made a 4,000 watt version they just used the same engine. This thing would run forever at that 2,000 w load you would never wear that engine out it's barely working at all. Or perhaps they just designed them all this way so they can work reliable for 75 years.
It would be interesting to put a modern fuel injection system on an old engine like this with a digital governor and see what you can get out of it. Personally I kind of like the old mechanical stuff. But it'd be interesting seeing what the fuel efficiency would be with a fuel injection system.
Today's generators are not very well built for the most part they're just disposable items. These things were built to last and run in difficult environments with little maintenance.
I love the Art Deco touch.
One sweet sounding engine!
You explained the governor operation very well.
Well, I worked in a power plant. On a island where we generated our own power

By producing your very informative videos you are not only showing your ability to transmit well, as well as a good level of language, but you are making a real gift of your knowledge and it is greatly appreciated. Hoping there is teachers of your caliber in order to support the interest of those who want to learn, to ensure the succession and the transmission of knowledge. Be well. (I speak several languages but geeeesss, I don't speak electric ;-) )
A very nice Hydrocarbon to power converter .
Good stuff Mike, thanks and I'll look forward to more videos.
1945, Wow! It's hard to believe that was 80 years ago!
@William Mulvaney True, I love the look of it, Mike could explain the reasons for low power raring.
I think of them like a See-saw, with a balance that can shift away from center. A heavier person can balance a lighter person if the balance point is shifted.
Nice Job on the Old Timer - the part on the governor was extremely informative.
This is it, with modern kit, we can expect perfection, and reasonably assume will get perfection, but we tend to forget that in times gone by, things were built with a greater tolerance and wider scope for adjustment. I could well imagine some old guy from back in the day taking a look at that and saying something like "Well I'll be..... I never knew these things could govern so precisely. What's your secret, son?".
It all comes down to what we've grown accustomed to, and what our expectations are.
@William Mulvaney You got that right, and a lot more repairable in the absence of all the modern fancy electronic gizmology. Also built to last a lot more than just a couple power outages!
Good job buddy! :) That's such a cool old unit, and you've really made quite an improvement in its performance.
11:00 bullshit, you’re doing a fine job explaining
I love your work and choice of machinery. The new stuff has a bundle of wires running into a circuit block. The older stuff shows you what is happening. I couldn’t help thinking of an old book of engines. It said gasoline engines max efficiency is at 1800 feet per minute piston speed at half throttle. I wonder how close the generator is to those operating conditions...Paul
Takes an overload, like, no problem. That's a great generator right there.
Tanks for your great videos. I follow you with great interest. I love these old machines.
I learn a lot from your videos.
Keep up the good work.
Thanks.
Great teacher...thanks for all your efforts and time
That's a smooth running little generator.
Awesome video! You explained the operation of the mechanical governor very well. The drawing really helped. Very well done!
@ Small engine mechanic: I recently had to junk a B&S 10 KW generator. The stator was shorted and the unit was a 1996 model. The owner said junk it. He wanted a new one.
I have the transfer switch and control panel. I have all of the prints too.
If you want this equipment you can have it for the cost of shipping.
I need contact info.
I like your videos. You sir are a great technician.
Thank you for explaining the governor theory of operation. I’m impressed by that mechanical design of fly weights, lever arms and spring rate all working together to maintain speed.
*- The time you took, Mike, to struggle through an explanation of how the concept of the sensitivity adjustment works, gave people for people to see it, study it, and understand it intuitively.*
*- The job you did of describing how it all works together was Good enough for us to get-it, I suspect.*
*- The longer the sensitivity rod is, the more authority of torque strength it gives to the spring.*
*- A lighter spring, together with a longer sensitivity rod, will have a finer tuning capability.*
*- A heavy, strong spring, will require a shorter sensitivity rod lever length, to keep the "pull" right, but it will have noticeably less "finesse".*
*- A lengthened positioning of the sensitivity-rod produces a long powerful lever, delivering a lot of increasingly more and more powerful torque of pull or turning of the "governor-shaft".*
*- There will be an optimal size/strength of spring, and optimal sensitivity-rod lever length, to allow for best fine level of timely response to motor rpm compensation-requirements per loading changes.*
*- What that optimal combination of spring strength and rod length will be will probably change given any changes in the generator's different job locations and their job electrical demand loading(s).*
Sweet smooth sounding generator.
I really like the way you explain and present the machinery, how they work and what can be done to fix any problems. You're very meticulous which is another thing I love about your work, And of course my special love for the old machinery you tend to find and present. I subscribe to a lot channels, but only a few will I outright miss when I can't watch them for some reason. Needless to say, I was very happy when I saw you posting new material for us to enjoy. Thanks a lot for taking the time and effort, it's much appreciated. Greetings from Sweden.
Thanks….now I understand governors. Love your channel. Always great explanations.
Excellent follow up and tutorial! You did a great job explaining to function of the governor. The sensitivity adjustment is generally there to compensate the spring’s spring rate (kx) due to manufacturing tolerance and governor geometry tolerance. I Love watching your videos and learning more about electromechanical equipment. Thank you for sharing your knowledge and taking us along!
Getting an old generator like this and fixing it up is better than buying a brand new one imo
When comparing the droop between full load and no-load it's actually more sensible to compare full load to a very small load rather than a zero load. I was always told never run a generator without some sort of load, typically a shop lamp is used, so 100W.
Such a beautiful well built machine.
awesome video ! like to see them old gen sets!
Nice beastie. Almost stable enough to run an old clock. The extra throttle is for the famous Onan overhead. Enough extra generating capacity to cover any surge. Try a 50% overload on one of those modern inverter generators.
Hi, infind it amazing how youre able to get those old generators up to run and measure the load they can supply. Its all pretty cool
it is actually the spring's relation to the tangent this varies the amount of inverse feed back.
the more the alignment of the spring is above the tangent the more inverse feedback.
for example a clutch over-center spring, where the spring's line crosses the shaft axis, then gives positive feedback
Great videos as alway and very informative
Maybe one day you could give a "day in the life" of your daily job and a comparison from these old girls to the more modern machines?
Better than new,,,nice job Mike.
Those little generators in the background, I'd love to know more about them. I recognize those engines from a go-kart I built long ago. I never knew the engine model.
Thought you did a fine job in showing how it worked with the; weights, levers, spring and Carburetor. Thanks for sharing Mikey, I always learn something from you. Best Wishes & Blessings. Keith Noneya
Nice job! What a neat old generator!
Excellent governor performance for a mechanical unit. No hunting, even when set to maximum sensitivity. Amazing that gen set has so much extra power capacity over rated load, especially considering its age.
I think your explanation was perfect. Thanks for all the lessons!
Nice! A little bit of fiddling and thinking really garnered some fine results!
Great job Mike ! That made a world of difference . Great genset there , I really like it . ENJOYED
Nice problem solving. Met you and saw this gen-set running at Jacktown. Good machine.
Thanks for the excellent videos on this beautiful old overengineered machine!!
Purely mechanical, no hydraulics, no electronics, that's why it's still on the planet and still working..
Is that a new Bronco Sport I see under the carport ??
That's beautiful too !
@6:28 VERY CLEAR !
Nice sketch, good explanation.
This great channel is withering on the vine. You need to upload rapidly. Thank you
Collecting footage is the easy part of creating videos. The hard part is doing the edits, even simple ones are very time consuming. Anyone that does videos as a side gig isn’t going to be able to produce like some of these full time You Tubers.
i like your vids, you are a natural teacher.
I like your fork lift looks like a case 530 , I have one just like it , I just picked up a 4000 w onan gen set probably 50 years old with no more than 35 hrs on it , it runs on propane, good a stand by .
Thanks for showing! Very good explanation!
Running lovely, wonderful job, keep it up! 👍
Runs mint!
Good demostration. Thanks for the look.
Lovely old machine! Sounds great! Your neighbours must love you! 🇦🇺🍺🍺
Wonderful Mike thanks for sharing 👍
I have a Generac from the 90's, 10 horse Tecumseh, 5000 watt that hasn't run for 5 years. After watching you, i want to get working on it. Ps wonderin if jacktown will be on this year for the fall? Cheers!!
Thats impressive! Well done. Good as or better than new current day gens! Best wishes!
Somewhere out there is the farmer who had this in his barn years ago and he's thinking he got rooked when the tech suggested he replace it with something newer.
Thanks for humoring us :-)
Nice job on the governor tune up.
Love your videos Mike.
