Default ONAN JB no tag

If I could get some help went and looked at a JB generator with NO tags, only the block numbers.
Any information would be helpful.

Speaking from experience, you will need to post some pictures at the very least. No tags are not quite a no go but most of the experts here can only give a definitive answer on what you have based upon tag info. Pictures can at least determine whether its a Magnacitor end or YD, extended stack, tri-fuel etc. I seem stuck with marine sets with tags gobbled up by bilge brine based upon where I live so I feel your pain.

Hope this helps.

Only thing I can say for sure; it is a magneciter set.

$100 ? What are the parts worth to you? with the exhaust pointing up and not plugged, you can almost be assured the cylinders and maybe lower end are full of rust.

If it were within 50 miles of me, I might buy it with the hopes that the starter and carb are salvageable. The sheet metal and other various parts would go in my salvage pile.

I would take it. If he would pay me to haul it off. Open exhaust most likely rusted shut.

Can try turning flywheel to see if it's free. But sitting for 10 years even if it was under a trap it might be seized. With luck you could get a few parts off it, but at $100......

Why don't these people at least put a tarp over it.

It must have been sold. The CL ad was taken down. I wonder who got it and for how much?

It's mine for the price of "Get it out of my yard!" I will pick it up next week.
Comes complete with a small trailer with flat tires...
I did pull the oil dipstick and it definitively has water in the oil. For the price of haul it away I don't think I can get hurt on this deal.
As for the distance I have to go to get this generator... less than 1 mile round trip

Thanks
Keith

Excellent! 1/2 mile each way? Make sure you fill your truck's gas tank for that long trip and get plenty of sleep the night before. Your don't want to fall asleep at the steering wheel 1/4 mile down the road

Free and travel distance make it worth it, even if just for some parts.
Good luck and post what you got after you get to look it over more.

Think I saw it was a magnaciter, that's a nice find.

Looks like it may be wet from rain , no tarp. I'ld dry out magnaciter and genhead for a week or more in a warm dry place before running it. Or put a flood light on it for that week to keep it warm and dry it out.

Made the LONG distance trip with my oldest son to retrieve the generator.
First picture hour meter 203.6 hours
second picture I filled the exhaust with diesel fuel (better than more water)
This one is probably a parts machine... Time will tell.

Can anyone tell me the thread size for the exhaust so I can put a plug in it?

I believe the exhaust is 1-1/4" standard pipe thread. Why are you filling the exhaust with diesel? Is the motor stuck? I bet it is nasty in the cylinders if they filled up with water? Did you drain the oil and if so what came out besides oil?

p.s. Did you use GPS for that long trip of 1 mile round trip?

If you can drain the water and oil out and see a clear separation then it probably has not been run with the water oil mixture . That probably means the bearings and top end are ok but the pistons and rings are rusted. Boring is not out of the question as oversize pistons are somewhat available. It is worth a close examination to figure out if it can be saved. If it can it is worth something and a very useful machine. You will have to do a bit of disassembly to figure out the condition of everything. I would certainly be happy to get a machine like that for free. Cheers Dan
