Evvy,
On your assortments of leftovers, is there any evidence that one of those rivets broke out?
Three brackets, six rivets. If I am wrong then every bracket should have the fiberglass disk underneath held by two rivets like the one in the picture I used

And you know, over the years Marathon has made some absolute bomb proof Main gen. Why reinvent the wheel? Something that works, works well, works for ever, should not be discarded!

I'll look again, but I don't recall two disks. Just brackets riveted to one wafer board. I suspect that's why Marathon pointed out that they didn't make this one... among other observations from my (growing) picture library.

I agree that they are top notch... my gutt is telling me to abandon this design and substitute one of their commercial products. I suspect that will lower my TCO, because repairing a commercial one will likely be cheaper than repairing a DOD spec design. Then there's that little voice that says... "don't give up... you've been here before!"

Got to do what you got to do. If you could score a main gen with the updated ring, life would be good. I bumped my buddy. Will see if he is awake. Or the Corona got him?
Now, I am supposed to be removing wall paper. If I don't get this done, my son will be disappointed. The only thing worse then taking paper down, is putting it up. And I aint doing that!

Too slow! Spray water on the wall, wait a bit, pull it off.
Almost done. Had to knock off for making chow. Listening to kick arsh Blues on Aardvark Blues, Internet radio. I could work all night!

Phase II
I still haven't decided about replace vs rewind, but no matter what, I've got to get the generator out of the cabinet. My generator set is mounted on a military trailer. I've got a couple of options. Tow it to one of you who live in NC, or take it out myself with Bob's help. I'm wondering if an engine hoist will reach in there with the trailer A-Frame in the way. I'll have to buy the hoist ao I can't just try it and see.
What do y'all think? Does anyone have experience with removing and reinstalling the generator? Would you please share your expertise with me?

It has a lift ring on it right? Got any neighbors with tractors/forks that you could slide a single fork into the cabinet and hook a chain?

Enzyme wallpaper stripper all the way! Much faster than water.... Keeps the room cooler than steam too! 
From the old days helping friends remodel their first homes back in our younger years!
To remove the gen, If you don't have a neighbor with a tractor available, some rental places will rent a cherry picker for cheap!
Just make sure you have room for both the boom and the legs. If vertical space is an issue, skip the hook hanging from the boom and use a short chain and shackle over the boom and through the lift eye and wrap the chain behind the original hook so it can't slip off. will gain you and extra 3-4"

It’s not out of the question. There isn’t anyone around that I know, but I could rent a loader. I used to live in RI. I think I could probably find you!

Why no! Never did it before in my life.
Take the control panel off. Take the rest of the box off. Take anything off that gets in your way first. Then get someone to use a forklift or tractor, like LITD wrote.
This kind of a lift might work. Its supposed to be 2 tons lift. After all, you just need to lift it high enough to pull the trailer out.
This is what we would use at work. Low tech, and in comparison to an electric crane or lift, cheap. For someone like you, perfect, but pricey. And you may only need it once in a blue moon. So buying one is maybe not in the cards for you. Perhaps you can find someone who has one and will bring it over. They can be easy taken apart. If I had had the room someplace, I would have stolen one from the Army! You need to find someone with a fork lift or tractor.

Food for thought! If I remove the cabinet I have the structural support above that I could put a come along on it and pull the trailer out. That’s doable and easy to get the pickup under it. Yeah, yeah… I’ll say it before anyone else does. Back the pickup in with the tailgate down! 🥱

Where are you working? Inside or out? If inside, and the building is sturdy enough, then you have a quick and dirty way. Ring in the roof and a come along/chain fall.
