Stuck Kubota Engine - Will It Run?

Someone threw away this 5000 watt Kubota generator. I know nothing about the history of this generator or why it was trashed. Most of the wires are disconnected and the Kubota engine is seized. Its not looking good for this machine. Lets see if I can free the engine and fire it up. Will it run and make power? Not sure, but lets find out.

As I suffer of depression and anxiety I spend my days watching a ton of your videos, I find your videos so relaxing, very detailed and your voice is so calm and you speak wisely, you Mr James Condon you are 👌 TYSM for sharing your knowledge

[@troyyarbrough]

James, you have more perseverance than anyone I've ever known or seen. Great job resurrecting that old dinosaur. It's my thoughts that the reason generators like this one have little resale value is because everyone wants inverter generators now. People have been educated on the "dangers" of using "dirty" electricity on these newer electronic devices. That particular Kubota generator would be great to use on a jobsite running power tools. Thanks for the awesome content.

[@Ken-rk3by]

I was gonna mention it would be good for power tools on a job site too, but you beat me to it. lol

[@-paganless2-432]

Furthermore the difference in size, weight, noise and fuel efficiency will probably seal the deal; well, it did for me.

To clean up the needle seat you can run a Q-tip in a drill with aluminum polish-valve grinding compound or toothpaste to clean it up. I also remove ring ridges on the rubber needles with a tool I made. You can cut the head off of a 16 penny nail and place a piece of fuel line over the nail. You can then push the needle into the fuel line and run it in a drill on a piece of 1500 sand paper with a little light weight oil. This will fix a leaking needle and seat on about any carburetor. You amaze me with the diagnostics you perform on these generators. Thank you and keep them coming.

[@brucejones2354]

One thing that might add is this. To prevent rust from forming in any metal container, is in the final rinse use a weak dilution of sodium nitrite ( NOT sodium nitrate) in the rinse water. I (in the long past early 90s) used to manage a barrel reconditioning business. To prevent rust from forming in the drums we used about ½cup of sodium nitrite in 1,200 gallons of water in our final rinse. This works extremely well. To give you an idea of how good this is, one of our customers supplied chemicals to Morton Thyocol to use in their rockets for the space program. There was never any problem with the sodium nitrite we used in our rinse. Be aware that sodium nitrite is commonly used in the process of removing rust from coils of steel before it is used in the manufacturing of car parts, for example. It is cheap, and works extremely well in fuel tanks. Just thought this might help someone.

I love the cardboard with folded-in edges (36:42) to keep the oil from getting all over, great idea!!

[@lv_woodturner3899]

Wow, this came back from the proverbial grave. Very well done. I can appreciate why you did not take the engine apart due to the expense of the parts. I was expecting you would put your bore scope down the spark plug hole just to see what the inside looked like. Amazing how well this runs now. It did not take long for the smoke to clear. My Generac 7000 W generator has a tiny Sealed Lead Acid battery so the new garden tractor battery likely puts out more amps than my SLA battery. Dave.

[@MsDave64]

Amazing that old boy made it. I am sure there is someone that will give it a good home now and keep it out of the land fill. That vacuum set up on the Carburetor was a work of art back when this was made as was the low idle set up. It even had a low oil sensor. Remarkable. Nice work. (Bet there are no plastic gears in that thing.)

[@billabernathy1541]

Nice work, James. Another DOA brought back to life by you. I'm glad you did not have to tear the engine down. Looks like a strong generator at this point.

Me too. It would have been unlikely I could have used the parts on something else. Glad it came back.

Another great video James thank you, I’ve seen people attach gravel/nuts and bolts filled gas tank to a rear tire on a jacked up/raised riding lawn mower/tractor and let it spin around for 1 to 2 hours in 1st gear and this seems to works quite well for cleaning rust out of a gas tank.

[@tomseipert3755]

James, I love watching you diagnose each component, then figuring out the solution. Most of us including myself lose patience and that affects us in finding the solution needed. I also echo a previous comment about the video quality of your work. I always learn so much more with each different machine you work on. Thanks for all your great videos, YOU are teaching a lot of us out here, and it is greatly appreciated !

[@johncourtneidge]

Yes!

[@additudeobx]

It's a bit different motivation when you also have the time invested into the making of a KZbin video that needs an ending.

It's interesting to hear you reasoning about the feasible alternatives, both technical and economical, while fixing this. Some elbow grease instead of a new tank got you a long way. Speaking of Kubota though, I'd love to see some diesel powered generators here.

It is gratifying to watch you put a machine that was given up on, put back into a good working condition. Good video.

[@Jameson4327]

This is why I enjoy watching your channel! Keep up the good videos.

[@yakacm]

I've been watching a few of these videos, and I'm trying to work out why they are so engaging. I've came to the conclusion that it's because James is so thorough. There's another channel like this that I used to watch a lot, but they would always have numerous things going on. Quite often they would start something and never finish it, which just leaves you a bit frustrated, that you'd bought in to the project and there had been no conclusion. I like the way James videos are self contained, and that he also tries very hard to address every aspect of a machine, and not just half ass it, leaving bits of it still non functional.

[@ghettsumm7949]

Wow! You brought this one back from the dead! Once the smoke dissipated, and you adjusted the governor, it was ready to rock!

[@benkanobe7500]

Fantastic Save. Perfect Gen for a Contractor. I really appreciate that you checked the waveform as I think there is value in getting a feel for how much variation there is from a pure sine wave amongst all these different Gens.

Wow. Not what I was expecting. More information in this video than I think I got out of pretty much any of the college courses I took back in the day. I'm glad that you do what you do and share it out here. I'd say that you would make an awesome teacher, but... better phrasing would be "you are an awesome teacher." You're really good at explaining your thought process as you diagnose a problem. Nice work and thank you for sharing.

[@sikes185]

I watch several people on KZbin on how to fix things. I like your channel because you make things simple to me. I have 2 generators one Briggs older model around 2015 and a Robin Subaru r1100. I got it during Katrina. That is all I could where I live in Mississippi. And I have a John Deere js35a. All 3 had carb problems. Well the Briggs I didn’t touch because I converted it to propane which I love. The others, after watch a lot of tour vids, decided I can do this. Well I bought a gallon of the carb cleaner. Needless to say I cut my grass for the first time in about 2 years with that John Deere and the little 1100 cranks on the second pull every time. Just wanted to say thanks. And I’ll keep watching Glenn Mississippi

[@graeme8755]

James, you are a marvel. I also watch Matt at Diesel Creek he had a very similar problem as he poured many acids into the tank to clean out the tank. When her was happy finally happy with the tank was to dry the inside. He used a dry rag and with the aid of compressed air to blow it around , thus drying the tank with out the rust inside of the tank heater was able to restore the tank back to full use. I find so frustrating that companies allow rebranding in the little country down under. Keep up with the analysis. Thanks James.

Well done James. I really enjoyed your explanation on the stater wiring. You actually sort out the full wiring like a master. It would have took me days if not weeks to sort this thing out. For the fuel tank, could you not have retrofitted one close enough, and just fabricate some angle iron or flat aluminium brackets, like you did for the battery. Even though it would have lifted the tank 1/2 inch, It seems the original tank may not last long with the extensive damage inside. Further, if you ever write a book on fixing generator, I wish to be the first one to purchase it. Have a great remembrance day weekend. Cheers.

[@wolfman007zz]

I had a similar problem on a Predator 8K generator. Stored it for 6 years, with fuel in the tank. The engine wouldn’t turn over. Fuel tank was full of rust flakes and scale. Fuel cutoff valve was inop. All fuel screens in the tank had disintegrated. Carb completely clogged. Thankfully clone parts saved me, for the tank and carb! I did what you did for the engine: PB Blaster soaking and breaker bar turning. This was all before I had ever watched your videos! Took me $60 to get my generator running. Now, I drain the tank and seal it from air during storage. I crank it and run it for 20 minutes every month, with the house transfer switch. It powers everything, including my house’s air conditioner!

[@vipvip-tf9rw]

is it stored outside?

[@wolfman007zz]

@@vipvip-tf9rw No. It was stored in my large shed, so kept dry. But it was subject to seasonal temps and atmospheric humidity. These Predator generators have a weak spot; the steel fuel tank will rust internally very easily! The generators with the heat shield and polyethylene fuel tanks are MUCH better if using gasoline for fuel.
