The rear bearing retaining clip is missing on my Onan, allowing the bearing shell to spin in the housing. It's an aftermarket bearing that doesn't even have the slot for the clip to fit in. I have an Onan replacement bearing, but the clip runs from $177 to $440USD!!!

From my readings, the bearing needs to slide in-out of the rear housing to allow for expansion from heat so it can't be fixed in place.

it looks like this:

Has anyone made up a clip? I'm looking for ideas.

Thanks

I saw one on ebay for $40US plus shipping = ~ $75Cdn.

I was hoping someone had come up with something a bit more reasonable cost wise. Over at smokestak forum someone suggested a small nut and bolt, but I don't know how long it would last.

Bruce,

I have never been into that end of an Onan, but I have designed a lot of strange stuff.

Were I you, I would call Jim Miller in Hamilton OH, and ask if he has any ideas. As he has rewound fields, he has to have seen this and may have an idea how to replace it.

That clip appears to be an rotation stopped for the outer race of the bearing. I am amused that they thick so highly of the part.

The only critical part of it is the spring temper. I am guessing that the Onan bearing has two cuts ground into the outer race and that spring is supposed to hook into those and ride into the end bell when during assembly. It sure was a cheap answer 50 years ago.

As it is a double sealed bearing and open at the back there has to be some way to put something in there that will serve. I will have to look at what I have when I am out in my barn next. I don't think I have one loose, but I may have an idea if I look at the beast.

We replaced the rear bearing with a standard bearing and ground the outer race to fit the clip. That sucker was stuck in the bell tight! At least some of the newer Onans don't use the clip and use a chemical bond like loctite. Here is a image of what it looked like.

When I have the old clip I will take a die grinder and make two small notches (one on each side) in the outer race of the new bearing and put the clip on. If I didn't have a clip I would just fashion one up out of a piece of tough steel and do the same thing. That bearing doesn't have a lot to do back there and just about anything will keep it from spinning. Heck, you could probably assemble the machine and drive a chopstick into the slot in the bell housing to keep the bearing from spinning.

If it were me I would not loctite it. It is difficult enough to remove the rear bell housing when disassembling the machine..loctite sure wouldn't help.

The bearing is a 6206 IIRC.

There is one of those
Clips in my garage. It went flying when i took my bearing off my old onan. I could not find it, but my garage is a mess. I parted out the rest of that onan. I knew that clip was going to be an issue when it came time to putting that onan back together, but that is no longer going to happen.

If i ever see that clip again, i will make sure I mark it and keep it.

Jim has your answer it looks like.

I have heard that Jim Bounds has an Onan JUNK YARD. You might call him.
