Was on the hook over Labor Day weekend and the generator stopped.
Opened the impeller cover and half of the blades were missing. So I got out my spare and started the replacement process.
It took me two hours to get the old impeller out. Access is tough on my 390 MY, but I had done it before on a cold generator and didn't have an issue getting the old one out.
I assume that it was that the impeller was still hot and I couldn't get a grip on the rubber. I would just pull a chunk of it out and the impeller would move little, if at all. Finally got a drywall screw into the base and slowly pulled it out (after several attempts that just pulled the screw loose).
I still have the old impeller with the screw in it, and it is SOLIDLY in the (now cold) rubber.
Just wondering if anyone else had the same experience.
Yes, I could have waited for it to cool, but then it would be midnight or the next morning, and I wanted to get it done.
Was hoping for a couple seasons on the impeller. I guess this will be an annual replacement item from now on.
