Well- got my 803 up and running. Thanks to Light in the Dark located 2 parts machines. So off to Vermont I went and picked them up. Took 1 apart for flywheel and put mine back together. Everything works perfectly. Thanks for everyone’s help. I have 2 engines (don’t turn) and 2 generators. Good...

Sorry he has it in parts and misc.

Also in the parts for sale there’s a guy selling a whole 803 but I can’t figure out how to message him. I tried to start a conversation but no response?

Yeah I already did that.

Still looking for a flywheel. Anybody?

Without a doubt!!

Yeah looks perfect. Thanks

Thank you for that info. It could very well be true. I am trying to find bolts for it also. The finer thread makes it slightly more difficult. Maybe someone that has a flywheel will have bolts also.

When I purchased this unit it had 12 hrs on it. Real hours. You could tell by how everything was new. Everything. Most hrs that I put on it were very low load. Not that it matters. And as I said the engine was still running when I realized it wasn’t generating. Running rough because of no...

That would be wonderful. Let me know. Thanks. Jim. 732-664-3051

Haven’t had any luck with the suppliers being able to send me a picture. Still not sure of the correct part #.

Yes sir. Will do. I will call them in the morning. Thanks for the help. Jim

That is true but I think the part number that was mentioned is for the 400Hz machine?

The 186 6467 one that I see on the Onan website parts book shows a much smaller flywheel than the one I have. That number seems to look like the one that fits the 400Hz machine according to TM.

What I am also concerned about is the 60Hz machine and the 400Hz machine have 2 different part numbers in the TM and they look totally different?

The # in the TM is 104-1744

So am I safe to order the 186 6467 ? I sure appreciate everyone’s help. And it is a very heavy flywheel so I can see an engine problem not running smoothly to possibly shear the bolts. I was gonna drop the oil and filter and see if there’s any debris in there.

That’s the # stamped in casting. The printed # is 30554-88-20234 MFR 44940

170-4287. I didn’t see any pictures on the ones that I looked up with that other part #. Just wanted to make sure I was ordering the right one.

Yes it was running but poorly. I was assuming with the flywheel not turning it had no balance or counterweight to keep it smooth. Although something else could be going on? And I am concerned about WHY the bolts broke. We’re they never torqued properly? Or did something else in engine cause...
