I haven't, but I have done all the other maintenance on the generator. My coach is a 2015, so when that needs to be done, the generator will need to be lowered to change the belt. Too bad it wasn't designed to slide out like the newer coaches.

Usually in the 7 year mark is where they say to replace. Itís not a difficult job, just getting access to the sheet metal bolts. Top off left side loose and you can get the back off. Once you get in, change the water temp sender too.

You can get to the bolts by just lowering the unit without removing completely. I have also read people cut an access panel in the rear panel. The new Onanís have an access panel built in from factory.

OK, Now you have peaked my interest. We have a 2015 that would normally have to be dropped to do the belt maintenance.



Do you have any info on where an access panel can be cut to gain access to the belt ? I would love to do this to mine.


Any info is greatly appreciated. You say top of the left side...Is this the drivers side you are referring to ?

Here is a picture with the generator removed. The top and back panel have been removed. You can easily see the belt.

Give me a day and I will find you a picture of the access panel. You would have to cut sheet metal and the foil/fiberglas insulation. I donít think Onan has a retro kit, but even if they did you would have to remove the rear panel.

The belt is behind the rear panel, which is the one at the back of the motorhome, opposite the black panel.

Also if you drop the generator, donít forget to change the water temperature sensor. It fails at about the same age and is only about a 12 dollar item. It is the brass item, dead center of the photo with the white wire connected. Access is easy once you get the top panel off. Attachment 338075

Corc, What type of jack did you use to lower your generator ? Can you please post a picture of it ?

I used an ATV jack. Makes the job very manageable when used with coachís leveling jacks.

Hello Corc,
Sorry to keep bothering you but I want to know how high you lifted
your coach with the front jacks.

Also did you only lift the front with the jacks ?

After lowering the generator, did you have the coach high enough to be able to slide the generator completely out from under the coach ?

Thanks for all your help

I am collecting all the parts and buying a a jack so I can tackle this in the fall when it is a bit cooler. I also downloaded a service manual from Onan today for $9.95.
There is lots of good info in it. I think it was well worth it.

I was quoted $2,400 from Cummins today to do the work for me.
I decided I can spend my money more wisely than that,
$2,400 will buy a lot of steak, baked potatoes, lobster and beer.

Corc 08-26-2021 08:10 PM

I didnít move it all the way out, just lowered it with the jack and then raised the coach to give me some clearance to work. I didnít want to remove all the AC wires. I donít remember if it could have slid out all the way.

You just have to gain access to the top panel bolts. (10mm socket). Rear belt is easy. Need to raise RV enough for space on top to get to the water temp sensor. To gain access to the sensor with socket, I had to drill a 1Ē hole in the white cold/hot wall. Easy to cover up with tape. If the sensor breaks on removal, donít panic it can be rectified. Donít forget to replace this sensor, it will piss you off later.

Take it slow and you will be fine. Itís a bunch of beer you can buy with the savings.

Holler if you need help.

Sorry, but I have one more question. I plan on replacing the top and bottom radiator hoses, but on the engine diagram there is one called a "lower engine hose" did you replace it also ?


Thanks

Corc 08-31-2021 05:28 PM

My hoses were still firm and fine, I did not replace them. The radiator is near the top on left side front as you are standing at the front facing toward the back.
