Jason picked up this Generac XG10000E with less then 100 hours on the clock for $500. New they sell for over $2,000. According to the seller the engine is running fast. Jason connected the kill a watt and measured 97 hertz (5820 rpm). Generators without a load should be set close to 61.5 hertz (3690 rpm). Is the governor trashed? Lets find out.

James' explanation of how the governor works is priceless.

@er1073 Год назад

James your knowledge and experience definitely shows everytime you do repairs. Thank you Ed

@MrTonyPiscatelle Год назад

Nice job James , your friend lucked out on this one . I really like the way you explained the governor set up !

@bjusticeforever Год назад

WOW. It's THD is even cleaner than my dad's old Gen Pro II! Great diagnosis on the governor, and a FANTASTIC question about the idle limiter screw. It makes zero sense to have one that long!

@jayyoung5423 Год назад

Great diagnosis again....think I would have scrubbed off the 194 on the tank cover.....looks like auction material.

@mattdewater438 3 месяца назад

I’ve been through quite a learning curve with this exact same machine. Wouldn’t rev up under load to compensate. Turns out the pins that hold the governor weights wore out and looked like spools. The weights did not open and close properly. I found the issue and made this repair myself when my local Generac dealer said they couldn’t fix it. I could not have done it without the HUNDREDS of hours of watching your videos James. Also had plenty of help from our favorite “Bassguitarist1985” Thank you!!

@Roy_Tellason Год назад

It was interesting to see the waveform get cleaner as you put more of a load on it. I guess that speaks well to the design of that power head. That's a crazy design for the air box, almost encouraging dropped screws and other parts to go where you don't want them to go. I'd epoxy a bit of screen scross that opening to prevent this.

@dstanobiful 6 месяцев назад

Very informative, l live in Maine and was unaware of the summer/winter operation. Thanks again

@2005Pilot Год назад

LOL- We didn’t tell you about the 2 air box screws because we thought you were getting the blue locktite 🤣🤷‍♂️

@thomasstewart9368 Год назад

The "screamin-deamon" taimed, to a purring kitten with just a few adjustments. Amazing 👍

@Kuzzzzman Год назад

Another excellent video James, your friend hit the jackpot on this one. Your knowledge of small engines is absolutely astounding, great job with another diagnosis that most people wouldn't have a clue on where to begin.

@4Truth4All Год назад

Another great repair! What a nice machine. The best sine wave I've seen so far.

@benkanobe7500 Год назад

Another great diagnosis and structured problem-solving. Excellent!

@Kenny-rn2xc Год назад

That V-twin engine really runs smooth. You are very methodical in you diagnostics. Great job. I noticed that you didn't put the screws in but I just thought you didn't show us. Have a great week.

@martyb3783 Год назад

Every time I see you use that lift, I am envious. I am currently working on an old Universal Atomic 4 engine that is on a moving dolly and its kind of a pain in the ass to see things some times. Great video as always! You really are a genius when it comes to gensets.

@FarmCraft101 Год назад

Great explanation of the governor function and how to adjust it. Good video as usual. Cheers Jim.

@dragonmaker1541 Год назад

Excellent job as always. Very easy to follow a complex topic.

@rodneymiddleton9624 Год назад

I’m pretty sure that carburetor is used on many applications for power equipment. Great work as usual!!! I have a Honda EU2000i that I’m rebuilding the engine and lapping in the valves. Your video on that really helped me out! Thanks Jim!!!

@ron827 Год назад

Nice work as usual. A friend gave me an old riding mower that also over reved. I discovered the throttle plate lodged against the intake valve and the two screws with lock washers were eaten by the engine which was evident by tracks on the piston top.

@jeffbotkin1405 Год назад

Glad you showed how just a tiny bit of adjustment can make a big difference unlike the spring tensioner which you turned and turned on to raise the engine speed. Very interesting

@awofeowolabi2065 Месяц назад

As usual an exceptional diagnostic skills. Many thanks!

@jeffsignore7953 9 месяцев назад

Great video! Thank you for sharing your knowledge and experience! Much appreciated!

@raymondj8768 Год назад

That Dude scored 1 hell of a deal !

@iandennis7836 Год назад

Not half he didn't. You just don't want to ask what that'd be over here........put it this way, I'm looking at a Hyundai 4000W and even now after the winter scare we had with possible power shortages it's still £900 or about $1150. Whole home setups here are into the thousands. Nice bit of diagnosis there Jim, thanks again for another 'fix'😁.

@goodness-mercy 4 месяца назад

Awesome diagnosis - again!!! !!

@stevendufresne9994 Год назад

Thanks James for the Great Video! I learn something new each time!! 👍👍

@butler386 Год назад

Fantastic diagnosis and repair. That generator seems to pack a nice punch compared to most generators. More expensive but you get what you pay for--- sometimes. Thanks for the videos.

@fhazen01 Год назад

Another awesome learning video. Thank you James.

@TheOneTonHammer Год назад

Pretty amazing machine. Quickly and correctly diagnosed, Well done.

@markyoung7470 Год назад

James, I saw you missed those 2 bolts on the air box right away 🤐🤐just pulling your leg I missed it too, another great video with excellent camera angles followed by an excellent explanation of what you were looking for and what you were diagnosing as the problem all were spot on by the Master Gen Man.

@timd1833 Год назад

It might be a good idea to remove your original mark (22:28) and make a new mark where the slot on the adj screw aligns now. Later on, if something goes wrong with the idle speed, someone may notice the original (incorrect) mark and move the slot to align with it.

@brianallen9810 Год назад

I've always used a stuff called Dychem Cross Check on adjustments that I've made. You can see at a glance if someones tampered with adjustments or it's become loose.

@staind288 Год назад

That's excellent advice. Never thought about the next time in this scenario.. Good advice bud

@loucinci3922 Год назад

The back end of that clamp seemed to bottom out when tightened. I thought about hitting it with a points file to give it a little more clamping grip. But it turns out that was not needed.

@brianhind6149 Год назад

Excellent video as always Sir ! I always shake my head at some of the hack jobs that you unearth with these machines. If you promise not to tell anyone, in decades past I have been guilty at times of the same egregious actions. When you are young , nothing happens fast enough. On the other hand, some equipments are so poorly designed that I cut things out of the way, heated & bent brackets, & have actually redesigned electrical circuits so that parts could be found locally & installed in 10 minutes instead of hours. Yes, all electrical circuits were fused as close to the source as possible. Love your videos, & I have learned a lot about small engines. You were the man who explained to me what an "emulsion tube" was. About a month ago, I actually saw the word in print in an engineering manual Thank you James. Cheers! Brian

@MrAluntus Год назад

Wow, I had no idea how a govener works. Thanks for this tutorial.

@mtttony Год назад

Well done again James. I must admit the angle of the pinch gap on that governor arm looked like it was close to closing at the outside end. It looked like it had been over tightened at some point., One other thing is you would think a simple electronic rev limiter would be a good idea for safety if for any reason the governor or linkage fails. Thanks again, I watch every week and your video production gets better and better..

@watermanone7567 Год назад

Great work JIm. The THD surprised me. That is a good machine, I have not worked on that engine before. Thanks

@ni_wink84 Год назад

My guess is someone was in there tinkering around, great job as always James, I genuinely enjoy your knowledge and troubleshooting!

@wjodf8067 Год назад

Great to see you diagnose and work on a decent generator for once what a nice sine wave

@jonminer9891 Год назад

Hi, James. That was a step up from your usual trouble shooting efforts. Thanks for sharing! Stay Healthy!

@shawnmrfixitlee6478 Год назад

Nice and easy fix. great job James !

@paulravitsky2898 Год назад

I did yell at the screen when you forgot those 2 screws but then figured you left them out because you ordered a new air box....That's got a nice low distortion figure. Another excellent diagnosis and repair!

@roberteddy8962 7 месяцев назад

Very nice repair James .

@PeterDurrant Год назад

Looks like Jason got a bargain after your methodical approach once again solves the problem. Well done James. 👍Great video

@justinvanaulen2478 Год назад

Great video Jim! I have to say I LoL'd @ 23:56. You honestly sounded stunned! This was a good one. :)

@fayiznalu8411 5 месяцев назад

Good diagnosis..!!!😊

@porkchop955 Год назад

Excellent video. You just helped me choose my next generator.

@scroungasworkshop4663 Год назад

Well done again James. I was yelling at you twice, once when you missed the two screws to hold the air box on, but only because I remembered there were six and you only showed four, and again when you turned the DeWalt heat gun off and put the hot tip on the power cord but you just wouldn’t listen😂. I think the unanswered question is: why was somebody in there fiddling with the governor in the first place?? But I guess if the shaft slipped they may have been trying to back off the governor to slow the engine down. With their attitude of butcher the cover rather remove the fuel tank on an expensive generator I can only imagine what their car is like if they work on it. Cheers mate, Stuart 🇦🇺

@TonyWhite22351 Год назад

The hot tip on the power lead had me bothered too !

@arthurbiringer5676 Год назад

An excellent job! Keep up the great work.

@johnnybgoode6466 Год назад

well done James - only minor issues and your were able to detect and remedy them early on.

What a super clean Generator wow only 63 hours used on it she practically brand new

@pierremartel3552 Год назад

Let me tell you that you just demystified all of that governor work.. Thanks you very much!!!

@beaviswashere8009 Год назад

I wonder why it was so hot outside!!! James is Testing another Generator with ALL the space heaters! JK....😉😉😉😉 Great video and a easy repair :)))

Wow at the amount of melting on the air box cover

@johnhershey4010 Год назад

@wildefox1478 Год назад

Very simple fix on this one, just a simple governor adjustment, nice work!

@dannyj5688 Год назад

Handled that 9000 load flawlessly!!! Great fix!

@mjg263 Год назад

Nice clean output there, like inverter clean!

@Georgeolddrones Год назад

Another, brilliant video thanks George in England Uk

@gaad7938 Год назад

I have a 4500 watt& 5500 watt Generac. In the owners manual i believe there is a procedure outlined for resetting the governor. I've done it and both work perfectly.

@peterouellette3874 Год назад

Nice job, James

@MrAluntus Год назад

I bet.. what happened was when it started idling faster and faster, the previous-previous owner thought they understood carbs went in and hacked at that set screw to try to slow it down and eventually they couldn't figure it out and sold it. That's probably what I would have done before I learned how goveners work from you. I might have gone the extra step to remove the fuel tank though instead of melting the cover. And I bet the govener was lose from the time it was made. Very educational, thanks!

@liljoeii6091 Год назад

@ItsAlwaysRusty Год назад

Great video. You must have a great area for bargains. Nothing like that in my area working or not for $500.

@sumplais Год назад

I was a little surprised how much of a hit the first half of the load seemed to take and again after the full load - how little more it seemed to take.

@rich1953 5 месяцев назад

Nice generator high load values really good.

@howieab606 Год назад

I purchased one of these new, a number of years ago, and the speed kept on surging going up and down, up and down, would not regulate. Sent it back to the dealer who claimed to have fixed it, but I had the same issue still. Sent it back, got a refund, bought a Honda and never looked back. Until today! Impressive numbers although I would not be confident enough in the brand to try it again.

@markhelseth253 Год назад

Excellent video. I enjoy following the mystery as it unfolds. Very good tutorial on how a governor works. After watching multiple heaters get switched on and off - would there be an advantage to using an old vintage loadbank (Onan)? Might be a fun rebuild for the channel if one can be found cheap?

@willrobbinson Год назад

wow wander why the original problem if any, its very good out come WELL DONE

@GreyRockOne Год назад

Nice work James, that Generac is a beauty. Fantastic reading on the THD! Also, aren't those Magic Erasers great! I use them around the exposed upper part of my fiberglass in-ground pool, that is where all the excess sunscreen sticks to after it "floats" off everyone's skin while in the pool.

@jcondon1 Год назад

Good tip. I have the same problem.

@petergondolier4088 Год назад

You can easily make metal sleeves if you need to. I make them from soft copper tubing. It comes in various sizes from 1/8" ID up to 1.0" or even larger.

@GerardRusso Год назад

really enjoy your videos

@annierenard5954 Год назад

very good video, thank you

@mattdewater438 3 месяца назад

Found out the hard way not to pinch the fuel tank vent line after using the generator when you secure it in a trailer. Came out the next morning to find a collapsed steel fuel tank! 😂

@tubeDude48 Год назад

As for the video- you always do a fine job! 👍

@somerandomguy3868 Год назад

While I'm certain you put it together the way it was designed and intended to be the air filter pleats seem to be on the trailing side of the flow, at least as far as the filter media retaining screen is concerned, good explanation of the problem and fix

If you need it to blow a rod we can duct tape the leaf blower to its intake. If it runs a little lean... I've got 12 cans of starting fluid

@arthurbiringer5676 Год назад

Maybe a dab of locktite on those screws would be a good idea….

@phbrinsden Год назад

Those V twins are so much smoother and quieter than single cylinder engines.

@hieyeque1 Год назад

It's not an idle set screw, it's a self-destruct screw! I don't know who makes the engine, but the idle set screw being there is likely for other applications for the same engine...maybe. But that THD, tho! WOW. Thanks for the vid.

@davidschipsi1316 Год назад

Besides the connecting rods breaking from high revs the stock flywheel is vulnerable to exploding from centrifugal force. I had a screw let loose and got sucked into the engine, beat the hell out of the spark plug but that was it. Lucky.

@Mikelp73 Год назад

Wow man that’s a powerful gennie

@phillipbecker453 Год назад

The governor adjustment clamp was bent to the point where there is insufficient clamping travel left to hold the rod allowing it to increase speed! It was at contact point preventing any further adjustment.

@jackpatteeuw9244 Год назад

To remove stuck small diameter fuel/vent lines a custom made tool is a good solution. Take a straight pick and round over the point with a file/grinder. Put a 180° bend on the tip. Slip the rounded tio between the hose and the nipple. Work it around the inside of the hose. A small squirt of silicon spray or WD40 with the pick still inserted and the hose should come right off.

@whitesapphire5865 Год назад

As you'll know, James, those pinch bolts on the governor arm are prone to slippage on a whole raft of engines. The trouble is, there's no easy way to make them slip proof because of the need for infinite adjustment, at least, not without making the design much beefier and chunkier. That was a good exercise in tracking down the problem, and an object lesson to all, on how this adjustment can go awry, and how to get it back again. We used to maintain an older lawn tractor for a neighbour, powered by a Briggs and Stratton engine with the same governor setup. I think it would be true to say that it needed resetting every year, or at least, every second year. Just the nature of the beast I think.

@Rorschach1024 Год назад

If the shaft were milled with worm gear teeth and had a captive screw to drive the teeth, you could adjust the setting much more precisely and it would be unable to slip.

@staind288 Год назад

The governor shafts should all be made with splines. That would help A LOT

@whitesapphire5865 Год назад

@@staind288 But would take away the infinite adjustment.. The whole purpose of the smooth shaft is to avoid any notching in the adjustment. With splines, you'd be in this one, that one, or the one on the other side, but you wouldn't have the ability to be somewhere in-between. It would make the adjustment rather imprecise.
