DIY! Replace the Carburetor on an Onan 5500 Marquis Gold Generator

- Does your Onan generator take a long time to start? Does it stop running after you release the Start button? Does it run smoothly for 30 seconds before it stalls, or does it stop running after 30 minutes?
If you are experiencing any of these issues, it might be rectified with a simple DIY fix, or it might be a very expensive repair by an authorized Onan dealer. How do you know and who will you trust to diagnose and fix such a problem? Most importantly, can you repair it yourself?
In this video, I share my journey troubleshooting the cause of the premature shutdown along of my Onan Marquis Gold 5500 Generator in my 2001 Fleetwood 32h Bounder, and my efforts at fixing it myself. I am not a mechanic, so I have depended on my life experiences and the Internet to learn about similar issues with gasoline combustion engines, and more specifically, this Onan Marquis Gold 5500 generator.
This is the second of three videos. In my first video, I share my diagnostic efforts and what I learned during this process of test and elimination. In this, my second video, I share the rather challenging process of installing a new carburetor and the failed results. In my third video, I perform some additional DIY troubleshooting and fixes until I have exhausted everything that I can do myself without the use of sophisticated electrical diagnostics. I hope that in my final video, the RV repair shop will allow me to include some video showing what it took to ultimately repair my Onan 5500 Marquis Gold generator so that you can learn from my harrowing experience.
Thank you for watching my videos and for your comments and suggestions!
Great video. I followed the steps and made this easy, but important change and it made all the difference. I used a carb kit found on Amazon for under $70. I rant the generator for a couple of hours back to back and no issues.
“Well that’s of no help” made my day!
Where are the other videos?
What was wrong with the installation?
Was the carb a good buy from Amazon?
Need answers now.
Great video. Made me go and fix mine!!!
Thanks for the Video
A little tip after removing my carb many times. It's easier to slide the carb off the bolts then disconnect the throttle linkage
Hey, Glen, yeah, that's a huugely good tip since I have gone thru sheer misery trying to pull-off and put on the linkage whilst it was still on the carb bolts. I've even bent the end of the spring-hook attachment and tried to re-attach it while the carb was on the bolts, and that was not a good maneuver -at all! Thanks for the heads up, and take care!
When I received my new carb it came with 2 new in line filters that was recommended to install both
The peace that goes out on those is the part under the bowel and they don't sell just that part mine did the same exact thing
Great video! Can you help me with my generator? I replaced the carburetor, but after I get in my generator runs with a weird noise. Looks like something losing. I can not find the reason. I.can send you the videos. Thanks
What led u to replace the carb? It didnt stay running?
Yup that's the part that goes out is that fuel cylanoid
I believe I would of tested the fuel pressure to the carburetor as soon as I unscrewed the carb drain and no fuel came out. If no fuel is making its way to the bowl of the carburetor … that’s the problem. The plug n thing on the bowl probably shuts the gravity flow of gas if the engine isn’t running. If there’s no gas at the carburetor? Work your way to the fuel tank. I doesn’t seem his problem was actually the carburetor. Something restricting fuel flow to the bowl of the carburetor. That’s usually the problem 8 out of 10 times
The 14 code is because the engine isn’t running right
Is that a crack in the spacer???? That could be a air leak.......
Hello
I have similar problem with mine...
Why did you write ONLY ONE FUEL FILTER IS NEEDED BEFORE THÉ PUMP ?
I have a Onan filter just before the pump but i have another one 16 inches before the Onan Filter...
Why would you need 2 fuel filters?
I just bought it and it's like its ... can its cause the problem?
@@ggasss With 2 filters, possible to be too restrictive fuel flow for the pump to pull gas through the first filter and push it through the second into the carb. You only need one, ideally prior to the pump.
The actually problem was a simple adjustment of the choke.Yes it is adjustable and you can tell it was running rich(smoke)and because I could see the butterfly was closed .You didn't need a carburetor sorry
Why didn't you finish your video? You left everyone hanging. 😢
well Randel, this is of no value to me ,,any body can change a carb,, but what abt the code 14, not much help to me...
Now here we sit and stillno what is wrong? Not much help😢
Thank you for your comment! I'm sorry that this video did not get to the solution. This was a rather frustrating troubleshooting process. Here's what was found to be the issue: Fixed! Troubleshooting an Onan Marquis Gold 5500 Generator - Part 3: czcams.com/video/XmqmIzm4nZA/video.html
Thanks for the response and still confused, do I buy a carb or just take it to the shop
Good question. I'm not a mechanic, but I did as much as I could myself then took it to the RV shop, twice. The second time is when they found the problem. At least by replacing the carb, I had eliminated that possibility moving along the diagnosis. Good luck!
That 2nd filter you took off, the flow was the wrong direction....it should have been pointing away from the carb.....that might have been your issue the Entire time
But he tried starting it after removing that second filter near the carb, and it still wouldn't stay running.
That arrow points in the direction of fuel flow; towards the carb, as it should be.
@@tbucket9367 I meant the one underneath, the one pointing towards the fuel pump and not towards the carb. Does that rubber line come from the tank or the carb? If it goes fuel pump, to that filter, to the line in the video, then to the carb then it’s incorrect….if that line comes from the tank, then into the filter, then the fuel pump and then to the carb it’s correct. Basically I’m saying to check the flow of the filter underneath at the fuel pump.
