Gonna comment again. Mine has been struggling to carry load, and now that I’m done, guess it was noisy also😂. Changed the plugs, and adjusted the valves as described. Now it’s quieter AND will carry both AC units, microwave, water heater, etc. no problem. Thank again!
I'm starting to think you are genius, clairvoyant, or a Cummins Onan consultant or all of the above! I have a later model of this genset, model 5.5HGJAB -6755K in my 2015 Momentum 350M and guess where the OEM mounts the fuel filter now...underneath the set just before the fuel pump. Still didn't keep the damn pump from going out. Have one on order. Thanks for this and your other Onan vids, you and they rock!
Awsome video. Was just going over my manuals making myself an excel spreadsheet to track my maintenance tasks and read about adjusting valve lash. What I thought is valve lash. After watching several videos I feel confident enough to do the job. But your video sealed the deal. You explained it the best and gave this ‘ol guy the confidence to do the job. Thanks
Hi Kevin! David in San Diego. My brakes are still going down the road, no hanging up, no leaking... Thank you for posting another useful video, gave me the courage to adjust the valves on my 5.5hgjab @ 650 hours; mybad. Took it up to 95% and it purrrrrrrrs. The rata-tat-tat kinda snuck up on me, froggie in a pot of water. Source everything breather, valve gaskets and plugs at Cummins Cal Pacific, except onan air and oil are on b/o for who knows how long, went with their fleetguard filter, $20 for a $11.63 onan, its about 1cm shorter than the onan. Thanks again!
Thank you for the kind words so glad you got that Onan took care of. and that your brakes are doing well, if you ever have any questions that i can help you with my cell is 606-875-0125 Kevin
Robert Hyde I was tipped off by the sound it was making when I pulled off the insulated side cover. I just wonder how many of these generators are running with loose valve clearances
Thank you for the helpful information. My generator is purring like a cat!! I only broke one valve cover screw ;-) apparently they're pretty soft, and they do not tighten to stoppage like most screws, so I kept on turning haha. Regardless, I am picking up a new screw today, and will consider this a huge win! The generator (800 hours) sounds so unison and conformed, like the entire timing has been perfectly adjusted. Pretty easy job thanks to this video. Thanks again Kevin!
Hi Kevin, many many thanks for the quality video. Very helpful to see how to adjust valves. Just purchased a toy hauler with 2007 Onan 5500 Gold. I also changed the fuel filter to a frame mounted version with a water separator bowl. You referenced a service manual that you can email. Will you send a copy to me?
Hello Kevin, Great video. I checked my valves when new, and they were .010. Wondering why factory set then loose from spec. I hope that the specs aren't wrong. Thanks Scott
I have a Onan 4000 generator with a hundred eighty hours. I started it one morning and it ran for 3 minutes and shut down with error code 14 displayed. I’ve tried to start it multiple times with no luck. Took the air filter off and it was soaked with gas, pulled the spark plug and it was dry. So I know it’s not getting gas in the engine, I just don’t know why. Any ideas? Thanks, Jim from Ca.
Hi there! Thank you so much for this video! I have a question for you. I have a bad gasket and when I opened the valve compartment to change it I noticed that the top valve has a little play but the bottom is totally stiff. Is that normal? Onan 5500/330hrs.
I thought it was normal, since one is exhaust (open), the other intake (closed). So, one has pressure on it, the other doesn't. But I'm not familiar with small engines.
The ignition system consists of the flywheel magnet and two ignition coil assemblies (magnetos) with integral spark plug cables and boots (Figure 7-3) and two spark plugs. If the engine does not start: 1. Secure the spark plug cables on the spark plugs if they have come off. 2. Remove and examine the Spark Plugs and replace, if necessary. Check and reset the gap to 0.025 inch (0.06 mm). 3. Conduct the Spark Check. 4. Replace faulty ignition coil/cable assemblies and set the air gaps. Spark Plugs The spark plugs must be in good condition and have the proper gap for top engine performance. To prevent cross threading, always thread a spark plug in by hand until it seats and then torque to 10 lbs-ft (13 N-m) if new, or to 18 lbs-ft (24 N-m) if being reused
Do you happen to know why would a onan 5.5HGJAD spec K Direct gasoline injection would be making some weird noises as if it had a bad carb. I guess it could be sounded as a small backfire and it turns off when you do a turn. This is weird to me im stumped
Thank you. Been told the generator needs to be removed to do this, but looks like that's not the case. If it's just you, I know it might be difficult. But would it be possible for you to record the whole adjustment from start to finish next time you do it? Be it with a tripod or have another person hold your camera?

Hey Kevin, thanks for doing this video, hard to believe those valves got that loose.
Robert Hyde I was tipped off by the sound it was making when I pulled off the insulated side cover. I just wonder how many of these generators are running with loose valve clearances
Excellent video, thank you for sharing, and being so generous to personally help us!
You are very welcome thanks for watching
THANKS!!! I don't need a valve adjustment quite yet. BUT, you came across the breather tube....Mine was crispy.
Great video! Thank you sir!
Thanks for watching
My manual does not say valve adjustment but professional service needed at 450 hours. thanks for posting. Very helpful.

Glad to hear you get her all tuned up. and think of the money you saved by doing it your self!! Awesome.
This is very helpful. Thank you.

Thanks for the video. It was very informative, and confidence inspiring! Do you happen to know the part # for the gasket?
Sure gasket part # is 187-6236 if you need breather tube it is # 123-2109
Hello Kevin,

Wow .010 is a lot for a OHV engine and they just keep getting looser as time go on.

Do you know the spark plug gap setting for the Onan marquis 5500 Gold RV?
The ignition system consists of the flywheel magnet
and two ignition coil assemblies (magnetos) with integral spark plug cables and boots (Figure 7-3) and
two spark plugs.
If the engine does not start:
1. Secure the spark plug cables on the spark
plugs if they have come off.
2. Remove and examine the Spark Plugs and replace, if necessary. Check and reset the gap to
0.025 inch (0.06 mm).
3. Conduct the Spark Check.
4. Replace faulty ignition coil/cable assemblies
and set the air gaps.
Spark Plugs
The spark plugs must be in good condition and have
the proper gap for top engine performance.
To prevent cross threading, always thread a spark
plug in by hand until it seats and then torque to
10 lbs-ft (13 N-m) if new, or to 18 lbs-ft (24 N-m) if
being reused
Did you get the new gaskets and breather tube from amazon?
I own a lawn mower shop and ordered from my supplier it still took about 2 weeks .. the parts went on back order
@@ktoutdoor do you know the part #? I can't seem to find them?... Please 😊

Hi Kevin! I need your help. After I replaced my carburetor my generator runs, but.worh a weird noise. I can Send you the videos how looks like. Thanks
Sure can you text me a link to my phone? My cell 606-875-0125 Kevin
@@ktoutdoor tried to contact you but your phone can not receive messages
Try again i have been getting texts today. Or just call me
Did this arise from receiving a fault code? Would this cause a shut down/fault code?
That's unlikely I could just tell by the sound the valve clearance was getting to wide. Email me and I will send you a repair manual kc5210@gmail.com
Thank you. Been told the generator needs to be removed to do this, but looks like that's not the case.
If it's just you, I know it might be difficult. But would it be possible for you to record the whole adjustment from start to finish next time you do it? Be it with a tripod or have another person hold your camera?
