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.

@brucejones2354 Год назад

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.

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.

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.

@lv_woodturner3899 Год назад

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 Год назад

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.)

I watch several people on RU-vid 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 Год назад

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.

@mrobi5797 Год назад

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.

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.

Nice save from the dump, it runs really well for an engine that was stuck, nice work bringing it back to life James! I like Kubota equipment, I have 2 older Kubota push mowers, one is just the basic model and is push only, the other is self-propelled shaft driven. It has a tiny driveshaft coming out of the engine going to the gearbox for the rear drive and is 2 speed. They are built like tanks, both mowers have aluminum decks and blade clutches. Parts for them are really expensive from Kubota too, I know this generator is a rebranded Yamaha but my Kubota push mowers I believe are made by Kubota themselves including the engines because I've never seen any other mowers like them.

Dear James: the amount of work you have accomplished on this old Kubota is awesome. Saved it from the trash really. I do not know what was making the engine so restrictive when first pulled free. I kept waiting for it to seize up. I don't think I would sell this to a customer until it had run under load for two hours. Seems good at this point. The oil should probably be changed another time, but all in all a good save brother.

Its funny how different people approach troubleshooting these small engine/generator units. I've done several and when I bring it home I don't even bother "trying" - I just rip the thing down entirely - crankshaft & piston out, valves out, stator and rotor out of the generator, wiring panel all apart, basically down to the smallest components, then clean and recondition every part and put it back together testing the pieces as I go. Wouldn't make for good RU-vid, and probably takes WAY more hours, but it's a hobby and keeps me entertained. I've rebuilt and sold a dozen or so in the last 10 years and I'm currently working on a 15 year old chinese clone diesel 7500W unit right now. It's in 1000 pieces. Old owner said the engine surged so I assume issue with the diesel injector pump so I ordered a new one of those just to try out.

I really appreciate your knowledge on the electrical side of repairs like this. I aspire to be as methodical and precise as you are in that aspect. But what I really really appreciate is your commitment to the learning and diagnosing the mechanical side of a project like this. For sure there are special tricks and tips and general knowledge in the field. (For instance, it's generally not a good idea to use power tools on anything carburetor. Big screwdrivers are best. And In a motor such as this one, valves more than likely won't be the issue with seizing as it is, like you said, a flat head.) But those are all things we, as tinkers and take-shit-apart-to-see-how-it-works fanatics, figure out as we go! Love the videos man!
