Also check out my video on exercising and carburetor maintenance for the Cummins Onan RV QG 4000 generator here: ua-cam.com/video/355iwj83LqI/v-deo.html
Not that I would EVER want to teach the teacher, but I did notice a couple of things from your video that will help you. First, I noticed that you were "priming" gas flow with the start button when the generator was already warm right after the oil change. Secondly, the reason it didn't start right up after the oil change (sputtered and shut down) was because it was horribly flooded. The PROPER way to shut this generator down is to only press the switch down for about 1 second it will shut down on its own. You don't need to hold it down until the engine dies out (looked like 6 or 7 seconds in your video). After flooding the carb too much on the first shut-down after your oil change you primed it unnecessarily again, totally flooding the carb again. LOL, it only took me 9 of the 13 years I've had this same Generator. it will help keep that mew genset running great. These gens can be very temperamental !! Learn how to read the codes that are given off by the number of flashes the on/off button light does. Most importantly "Exercise" this generator at least once every month for 30 minutes under some load, such as the A/C. which is about 1/2 of the max load. Lastly, myself and some others have been using Stabil 360 MARINE FORMULA fuel stabilizer. It costs a little more than the regular Stabil, but you only use half as much but it coats the system avoiding varnishing of the carb, fuel tank and inside the engine. Works like magic in all small engines too. You'll notice the difference over time. Don't buy too too,much as the shelf life is 2 years after opening. Great prices on Amazon or e-bay. i bought 32 oz bottle for $21, and I'm almost out. At 1oz per 10 gal of fuel (doubling it for winter storage) you can see we use this Gen a lot and go places where if it craps out, your going home unless you can find full hookups!! Most RV problems are self inflicted, and a part of the learning process!! After 25 years (10 retired with zero commitments other than my also retired wife!!) of RV'ing, when you think you know it all, you find out you don't!! Keep the Videos coming RV Habit!!
Hi Jim thanks for commenting. I"m always willing to learn. I will try cutting back on priming it and see if that is an improvement. I have read on some forums people hold down the prime button for 30 seconds! I was told just till the light goes on which is always less than 5 seconds. As for shutting off the generator I have tried only holding the stop button for a few (1 or 2 seconds) and the darn thing wont shut off lol. I do use the Sta-bil 360 Marine and I agree the stuff works great. After years of RVing this is the first rig I have ever owned with an on board generator. I exercise it every two weeks under load for at least one hour. Thank you for your help its always great to have experienced input. Thanks for watching and stay safe.
You're not using the primer correctly. Push and hold the primer up to 30 seconds. The longer it hasn't been run, if the air temp is cold or if it ran out of fuel, the longer you hold it down. The light does not mean it is ready to crank, but that the fuel pump is running. Notice how it started and then died quickly. The primer needed to run longer. If the generator has been run, no priming is needed. Its similar to not choking a warm engine although the primer doesn't ad fuel to the engine, it only fills the carb bowl. Doing this correctly will extend the life of the starter significantly.
Check out my other video about maintenance on the generator, especially if you don't run it every two weeks. It shows how to keep the carburetor clear of the effects of ethanol fuel. Thanks for watching.
@@RVHabit I I've already checked that one out I don't think I want to go to that much trouble just to clean out a carburetor. I'll just start it up and let it run but thank you
I don't know why but I lost several comments and questions. Someone asked does the generator need to be level to operate. The short answer is no. As long as your not parked on a steep incline you should be fine.
Good job. No info packet was included when I bought my 2018 Entegra Esteem. Just a quick start guide. No info on when to exercise. What if I need to exercise in freezing weather? Will oil be ok for short runs? Again, thanks for the info. More than I get from General Rv.
You need 15W-40 oil to run in freezing temps. If your running SAE30 oil, that is only recommended for above freezing temps. Remember to run at least at half load when exercising. I run mine for at least one hour when exercising. If you can't exercise it regularly make sure you're using a fuel stabilizer. Thanks so much for taking time to comment.
Going to be doing full time living in our fifth wheel, will not have power for a bit, how long can this generator run on a tank of gas and is it fine to run 24/7 if needed?
Well this generator runs on gas from the chassis in my vehicle. Most say it uses about half a gallon an hour. Based on my usage that seems about right. If running constantly i would stop it every day to check the oil level.
Hi, 25 to 30 hours is about right to change that break-in oil. I have a video on generator exercising. These generators do not like to sit without being run. I run mine every two weeks when my rig is parked at home. Also, in the exercising video, I find the Seafoam treatment works great. I have increased the mixture to 2 parts gasoline to 1 part Seafoam. Thanks for watching.
Few questions, so no oil or air filter? How do you know if it is surging? Mine is running fine but sometimes the stop button from inside the coach is not stopping the generator. Always starts when pushing start, sometimes stops when push stop, works well. I’ll need to do an oil change soon. Thanks again for the videos!
Hi the 4000 does not have an oil filter. It does have an air filter but I just keep an eye on it. It does not typically need to be changed as often as oil. As for not shutting off intermittently from inside. I would start with checking the switch it may be bad or have loose wiring. Good luck.
Very helpful video, thank you for posting. We have the almost identical forest river model - just a few years older, our only question is how do you reset the "change oil" message" on the control center panel inside the actual RV. We can not find a reset button or any info in the manuals. Thanks for any help! John.
Hi I don't know of any oil change message for Onan generators. It may just be a meter that indicates to change oil based on hours of use. Many of them reset after several hours of run time
I would only recommend genuine Cummins Onan Green Label parts. Always check your specific Onan 4000 for correct part numbers but here are links to the majority of the Onan 4000 generators. Cummins Onan Fuel Pump A047N926 on Amazon: amzn.to/3dSthra Cummins 1460705 Onan Carburetor on Amazon: amzn.to/2ZMU7eo
Hi, you cannot reset the hour meter. The hour meter is designed to keep a running total of hours for the life of the generator. Thanks for watching and great question.
@@RVHabit I myself don't use synthetic, thank you for your imput... Your video was the only one I saw that answered certian questions that the other video's did not cover ... thank you again..
RV Habit you will get a much cleaner oil change if you don’t warm the engine. Pull the plug and put it back when it stops dripping. It will take a little longer but you get a much better “change”. I usually pull the plug and come back and check it later that day. Also you can pour a little clean oil in while your drain plug is open to help flush out more dirty oil. This does take quite a bit longer but .........
RV Habit warmer oil does drain faster no doubt. It just takes forever for all the oil that’s stuck and clinging to internal engine surfaces and components to reach the drain hole. That’s why I choose to drain my oil with a cold engine after the motor has been sitting over night or longer. I’ll sometimes pull a drain plug and come back the next day. I realize some don’t have that kind of time so getting most of the oil out will suffice but I’m just picky I guess. I’ll also pour a 1/4 to 1/2 quart clean oil and let it run out as well. I feel that helps push some dirty oil from the oil valleys in the head(s). And like I said, this is all just my opinion but I have done a few tests and the oil is always cleaner on the dipstick after doing the cold method. Hope all that makes sense and helps.
RV Habit I know but to check the oil level do I screw it all the way in or just stick it from outside my generator is the Onan 4000 evap it doesnt have oil filter
@@RVHabit Where can I get or what size is the washer, I checked it for leaks, but once it started and ran for a bit, it started leaking. I assume the washer is bad.
I heard you say "T-30 for the screws'' but I missed what size socket for the drain plug. My generator has warning placards saying do not run without panels in place, so I had to start it from inside the rig.
Hi, that is true that the generator should be run with the cover in place so it cools properly. Starting it from outside for a few minutes should not be an issue. My drain plug requires a 12mm socket.
You can start it and run it with the panel off for a couple minutes while servicing it etc. That warning is don’t leave it off while running it under a full load for a long time. Someone may think, it’s hot and running hard, Maybe leaving the door open will help cool it. No! Don’t do that!
@@RVHabit I used my jacks also only to level the vehicle for adding the oil. I could only put 1.5 qts without overflowing. Onan does state as you did 1.6 capacity. I must had some still in the engine somewhere when I drained it.
Hey Lou I was looking for what oil to use on my propane generator 4000 . When I googled it, you came up first. I thought that was cool, ours is taking some time to prime up. Hope all is well. Life with ken and jane
Hi guys, I made the big time if I'm on top of google search woohoo! I don't know much about the propane generators but the gas ones take either straight SAE 30 for gas engines and if you want to use 15w40 its actually diesel motor oil. Hope you guys are enjoying your journey.
Thanks for the info. Just bought a used 2018 Leprechaun. Gen set has 180 hours and the oil has never been changed! I’m using Amsoil; since I’m a dealer. Gonna change now then in another 5 hours and hopefully it will flush any deposits out. It’s amazing someone will spend $100k on a motorhome and not $10 on an oil change... smh Thanks for the info again!!
Hi AJ, I am a big fan of Coachman RVs and the Leprechaun is a great rig. On board generators tend to be severely undermaintained. I would look into a Seafoam treatment also to help clean out the carb. The good news is it has 180 hours on it which means the pervious owner used it and Onan generators love to be used. It is when they are not used that they begin to have problems. Good luck and congrats on your purchase.
RV Habit I keep pints of Seafoam around the shop. However, bought a gallon to keep in the rig today. Full tank of fuel I placed 60 ounces in the main tank and ran the gen for an hour to flush it through as well as drove the rig for about 5 miles to “shake it up”. Thanks for the reply sir. Stay safe
@@Wegowing Sir what kind of oil did you use , weight and ect on your generator? I bought a 2020 coachmen freelander 21QB and Gen has 79 hours on it . They told me at the dealership that the break in period was 100 to 150 hours. After researching I found out its only 20 to 30 hours, no books came with my rig ! Any info would be greatly appreciated!
Hi Daven, I use 15W40 since that's what Onan recommends. The Onan oil can be a bit pricey. You should change the oil every year or 100 hrs., whichever is sooner. Air filters last a long time but at least check it when changing oil. The 4000 has no oil filter so it is a very easy process. Check out my other video on exercising the generator which is essential to keep it running well. ua-cam.com/video/355iwj83LqI/v-deo.html
@@RVHabit Already checked it out and sub bro you do great videos I'm Def going to do the sea foam treatment ! What brand of 15W40 oil would recommend if i don't use the onan brand ?
When Cummins says to change after first 20-30 hours, is that regardless of the time frame? I just bought a 2 year old rv. The generator only has 17 hours on it. Should I still change the oil. It probably wasn’t changed. I would imagine it would be a good idea to change it every year even if it’s the starting oil? Thx!
I personally would change the oil. The 20 to 30 hours is the break in period, 17 hours on a generator is not a lot of hours. I would get in the habit of running it under load for at least one hour every three to 4 weeks. These generators do not like to sit unused. They run better when they are used on a regular basis, Watch my video on exercising the generator. There are some good tips. Congrats on the new RV,
Also check out my video on exercising and carburetor maintenance for the Cummins Onan RV QG 4000 generator here: ua-cam.com/video/355iwj83LqI/v-deo.html

During the winter I would not want to run the AC’s to load the generator, would a space heater do the trick for 30 or so minutes? Thanks
That is exactly what I use during the winter months. A space heater is perfect. I use a 1500w space heater on high.

John C RV Good question. Saved me time looking over You tube for a film on how to change it. Oops, he told us at the end.
I so much appreciate your thoroughness. You show/explain every step and I need that. Thank you!
Thank you Pamela.
Thanks for the great information!! Especially the size of the 30 torx bit and 12mm metric socket used I really appreciate it!
Hi Amy, Glad it was helpful!
I heard you say "T-30 for the screws'' but I missed what size socket for the drain plug. My generator has warning placards saying do not run without panels in place, so I had to start it from inside the rig.
Hi, that is true that the generator should be run with the cover in place so it cools properly. Starting it from outside for a few minutes should not be an issue. My drain plug requires a 12mm socket.
You can start it and run it with the panel off for a couple minutes while servicing it etc. That warning is don’t leave it off while running it under a full load for a long time.
Someone may think, it’s hot and running hard, Maybe leaving the door open will help cool it.
No! Don’t do that!
You correct Joe. Thanks for commenting.
So I watched a few videos on these. Do these generators have no oil filters?
Hi, The Onan 4000 does not have an oil filter. Larger models do have an oil filter.
Is that a citizen ecodrive Skyhawk on your wrist?
Very good it is exactly that. I have had it for years when it originally came out. The best built watch I have ever owned.
Do you have to use the Cummins oil? Or will any do?
The manufacturer says yes you do. I personally use Rotella Oil for the Genny.
Thanks for a great how to video. I am about to change the oil in my new generator as well. This video is great. Thank you.
The oil change is so easy. The hardest part is finding the oil at the store lol.
Thank you for the video. My generator is giving me the over crank code. How can I fix this?
Is your RV raised by the Leveling Jacks. If so is this safe? Thanks for the video.
The leveling jacks are hydraulic. It lifts the RV only enough to stabilize and level the coach. The tires remain on the ground.
@@RVHabit I used my jacks also only to level the vehicle for adding the oil. I could only put 1.5 qts without overflowing. Onan does state as you did 1.6 capacity. I must had some still in the engine somewhere when I drained it.
Ever had generator without oil drain plug access
Do you know what size the crush washer is (or a link to a replacement)? I have a small leak and should probably replace it.
I don't have a link. I would try your local auto parts store or contacting Cummins Onan directly. Good luck.
Nicely done. Is there an oil filter to change as well? I don't see an oil filter part number in your low bar.
Hi, there is no oil filter on the 4000.
Hey Lou I was looking for what oil to use on my propane generator 4000 . When I googled it, you came up first. I thought that was cool, ours is taking some time to prime up. Hope all is well. Life with ken and jane
Hi guys, I made the big time if I'm on top of google search woohoo! I don't know much about the propane generators but the gas ones take either straight SAE 30 for gas engines and if you want to use 15w40 its actually diesel motor oil. Hope you guys are enjoying your journey.
Thanks for the info. Just bought a used 2018 Leprechaun. Gen set has 180 hours and the oil has never been changed! I’m using Amsoil; since I’m a dealer. Gonna change now then in another 5 hours and hopefully it will flush any deposits out. It’s amazing someone will spend $100k on a motorhome and not $10 on an oil change... smh
Thanks for the info again!!
Hi AJ, I am a big fan of Coachman RVs and the Leprechaun is a great rig. On board generators tend to be severely undermaintained. I would look into a Seafoam treatment also to help clean out the carb. The good news is it has 180 hours on it which means the pervious owner used it and Onan generators love to be used. It is when they are not used that they begin to have problems. Good luck and congrats on your purchase.
RV Habit I keep pints of Seafoam around the shop. However, bought a gallon to keep in the rig today. Full tank of fuel I placed 60 ounces in the main tank and ran the gen for an hour to flush it through as well as drove the rig for about 5 miles to “shake it up”.
Thanks for the reply sir. Stay safe
@@Wegowing Sir what kind of oil did you use , weight and ect on your generator? I bought a 2020 coachmen freelander 21QB and Gen has 79 hours on it . They told me at the dealership that the break in period was 100 to 150 hours. After researching I found out its only 20 to 30 hours, no books came with my rig ! Any info would be greatly appreciated!
Hi Daven, I use 15W40 since that's what Onan recommends. The Onan oil can be a bit pricey. You should change the oil every year or 100 hrs., whichever is sooner. Air filters last a long time but at least check it when changing oil. The 4000 has no oil filter so it is a very easy process. Check out my other video on exercising the generator which is essential to keep it running well. ua-cam.com/video/355iwj83LqI/v-deo.html
@@RVHabit Already checked it out and sub bro you do great videos I'm Def going to do the sea foam treatment ! What brand of 15W40 oil would recommend if i don't use the onan brand ?
When Cummins says to change after first 20-30 hours, is that regardless of the time frame? I just bought a 2 year old rv. The generator only has 17 hours on it. Should I still change the oil. It probably wasn’t changed. I would imagine it would be a good idea to change it every year even if it’s the starting oil? Thx!
I personally would change the oil. The 20 to 30 hours is the break in period, 17 hours on a generator is not a lot of hours. I would get in the habit of running it under load for at least one hour every three to 4 weeks. These generators do not like to sit unused. They run better when they are used on a regular basis, Watch my video on exercising the generator. There are some good tips. Congrats on the new RV,
@@RVHabit ok thanks very much for the tips. It follows the good saying: use it or loose it!
