- In this video I rebuild my genset after tearing it down to replace my rotor!
EXTRA NOTES;
At the end when my genset wouldn’t start cold on its own, it was due to an improper heated choke adjustment. The manual has it stated on how to adjust it properly for those who are wondering. I MIGHT make a video on it in the future, who knows.
Don’t use copper for fuel line, use coated steel brake lines (1/4”), they are the best for the application, I custom bent and flared mine, but you can find them at most auto stores.
Lastly, good luck to you all who decide to rebuild your Gensets, I hope to hear about it here if you guys choose to rebuild! Thanks for watching, I hope this video helps!
Awesome videos they helped me finish the restore on my generator which is identical
That’s great! I’m so glad my videos have helped, I hope your Onan Genset is running smooth after being rebuilt!
Really great learning channel. I'm installing used Onan and can now rebuild the generator head, thank you.

THIS IS HOW I FIXED MINE, IN THE CASE OF....
"I CAN'T START MY GENERATOR"
It's has been two years since last time it was running, so I started by checking oil level full at gen dipstick (it won't start if low oil because of sensors) then I checked gasoline more than 1\4 tank in the RV (also safety sensors), sparkplug checked for good spark, also checked the manual reset circuit braker ( to be ON) at front motorhome engine compartment for 12v current to the generator to be able to start it, also cleaned the carburetor and even installed new one but same situation, then checked wires and found some has been chewed like gum by rats at the back of starting switch generator panel so I replaced them, at this time the generator started but stay running only by keep pushing the switch on all the time, so then finally I knew it was internal electrical problem from the engine itself, so I took the generator out from my RV to work in my garage, (I did this by myself with some tools and old Mayan tricks ) lol, it's really heavy for one person.
I disassemble the unit at my garage and started by removing the cover, then the cooling fan or flywheel unit (it's 2 items in one) until finally I was at the gen rotor and brushes assembly area and this is what I found: one more wire chewed by filthy rats plus the stinky rat nest in the middle of the generator motor coil, I fixed the wire and sanded the commutator copper contacts where the brushes are sitting becouse they were real duty with old urine from the rats, and of course I got rid off the stinky nest, lol!!!
Then I assembled everything back together and... bingo it's runing like a champion!!!
For this project materials involved was about $60.00 including an aftermarket new carburetor and an harmonic balancer/steering wheel puller (available at any auto parts for $25.00) to pull the aluminum fan out and (flywheel).
Just picture this: (Any gasoline engine run smooth if gasoline and DC current aren't interrupted) so following this important principle you'll always find the problem to be fixed.
Also if you have a onan microlite 4000 like mine, don't run it for more than a minute without the cover because you'll cook the engine real fast, also keep the eye on the aluminium fan and your fingers after cranking it in case you missing one or two members...just kidding, lol!!!
After testing the gen then I did put the air cooling assembly back and the rest of components including the cover, now it's ready to be installed at my RV.
Once the gen was installed back at my motorhome I started it to be tested for electric power but not before flipping the electric switch (on) at the gen starting control panel (sometimes hiding under or around the panel) to transfer power to my RV GFCI main outlet and electric panel as well, my motorhome it's equipped with GFCI so I reset it and tested for green led light indicating power is ready at my main breakers panel, so I turned my main breaker (on) along the others ones but no power was present at my breaker main switch (faulty main braker) so I flipped it many times, sometimes you can make it work again, mine did work, lol!!!
I'm happy because everything works now including the ref for cold drinks and AC for this crazy summer, lol! Later I'll buy me a new main braker, for now this is a resurrected generator story that needed to be shared.
If this can help eaven one person to save time and $$$ it'll make me more happy, thanks for reading!!!
is there any after market alternator heads that could be adapted?
great vid, where did you get the rotor?
Thanks, I appreciate it! I’m glad you found it helpful! My new (refurbished) rotor that I installed, I found with the help of my friends on a forum site called “smokstak” it was on eBay if I recall. And it was a lucky find. So you will probably have to do some digging and make sure you have the right model number of your rotor, and you may be able to find a re-wound rotor on Craigslist, or eBay, etc. it’s u fortunate they don’t manufacture these anymore, so the only way to get one is to find an old one that was refurbished, or the long way which is to buy to same genset as you already have (not running of course) and part it out to use it’s rotor for your genset (always make sure you test your windings before you buy a broken set to ensure the rotor is in good condition). You can also probably sell off the remaining parts of the donor set that you don’t want, and they will normally sell enough to get your money back on the donor set, or most of it at least. But sometimes that route is cheaper if you have the tools and patience. Anyhow, I hope this comment helped, and if you have any further questions, feel free to comment them below!
