Check the back end bearing if you are taking the starter out. If that bearing (bushing?) is worn, the armature will soon eat the magnets.
I had one go bad in a 6.5NHE that had spent most of its life getting rusty and otherwise oxidized in an RV. Starter came out with little trouble.

Finally got around to pulling the starter today. The black gear was split in half. The starter sounded pretty bad when I spun it, so I decided to order a new one rather than try and rebuild the broken one. I ordered a cheap one that got good reviews on Amazon from people who claim to have had it installed for over a year, so we will see how it goes. Gotta love that free next day shipping though.

The starters have permanent magnets in them so they won't spin freely by hand. I would suggest taking apart the old one and rebuilding it, especially if it is an OE Onan starter. Then carry it with you as a spare. I carry a spare for my 4BGE because having my generator to run my AC in my 5th wheel is a must for my wife in hot weather if we have to stop. She has a med condition and over-heating is not a good thing for her. They are easy to take apart and re-assemble. The hard part is getting the spring clip on and off at the end of the motor shaft that holds the starter pinion gear on.

Good idea Motorhead. I think I could rebuild the original and keep it as a backup. Hopefully this new one will last but better safe than sorry.

While I had the generator pulled, I decided to check the exhaust really good because the generator was abnormally loud when I bought the RV. As I suspected, the exhaust manifold was cracked. I am going to see if I can get a muffler shop to weld it tomorrow, but I might need to replace it. Do any of you have a copy of the parts manual for this model? My email is precycled@gmail.com. Thanks in advance.

Look here for the manuals. Once you open it hold control key then hit F, at the top left will be a search box, type in BGE then hit enter, after that scroll down and BGE should be highlighted. I believe yours is a spec. P.

Thanks for all of the help everyone. This case is closed for now. The new starter is in and I was able to get the exhaust manifold welded up ok. I am going to rebuild the original starter and keep it on hand in case the cheapo model craps out on me. So far so good though. The generator starts fine and sounds much quieter. Now I get to go fix some leaks that this week's rainstorm exposed. Yay! These RV's sure are good fun!
