Onan 4KW cranks, doesn't start

[Sagecoachdriver]

My Onan 4KWQ generator with 50 hours in my 8 month old 2016 Forester wouldn't start Thursday morning as we were about to head home from Yosemite. It would crank but as soon as I released the start button it died. I checked and there was 3/4 tank of gas and the batteries we 90%. I then checked the carburetor choke and it was working and I could smell gas. We had plenty of battery power to bring in the slides and raise the levelers. I was able to get 1 4 trouble code which is high frequency. Once at Oakhurst, CA (cell service was intermittent in Yosemite Valley) I called my dealer and he referred me to a local Onan authorized repair shop close by. I called them and the said to bring it in yesterday at 8am. After much testing, the said the generator had to be removed as the problem lies internally. Late yesterday, I spoke with them and they said it was the bushings and that it appears there was some debris or something there. Anyway, they had the bushing assembly and it's back running. They need to finish reassembly and I can come in Monday afternoon to have the generator reinstalled. Under warranty, no charge!
Anyone else have issues like this? How easy is it to replace the bushings and does the generator really need to be removed?

They reinstalled the generator and everything seems to be fine. Does seem a bit noisier than before.

Sage, that is some bad luck. Haven't heard Onan having that type of problem so soon. Hope you won't have to go thru that again.

I know, I never had an issue like that with the same Onan in my 04 Winnebago Minnie. The authorized service center said it's not common, but does happen. I exercise mine religiously plus monthly campouts.

After re-installing the generator Monday, I have run it every day this week for at least an hour with the air conditioner on while I was working on the slide-out fascia. Then this afternoon, I got a lot of white smoke and it died. Had gas dripping from the air filter housing. Tried a few more times still smoking and died. Flashing 3 6. About an hour later, I tried again and it was working. I let it run for 30 minutes and shut it down. Just went out and tried to start it, sputters and won't start. I used my flashlight to see if there was fuel dripping and saw none. However, I noticed the label on the fuel pump was ready to come off and there was grey foam extruded from 2 spots on the pump. Could the pump be defective and release debris that clogged the carb?

Left a message at Scandavia Service, authorized Onan service, and they called back early Monday morning. I explained the symptoms and that we were about to leave on a week log trip. They said bring it right in. After a thorough check, it was determined to be a faulty fuel pump producing high psi. they replaced the fuel pump along with the air filter that was soaked with gas. All under warranty.
Got a late start but made it to the CG by 9pm.
Generator is working fines, no more issues. Thanks Scandanavia Service in Simi Valley
This had nothing to do with the earlier issue with the brushes.
