Re: Onan 4ky Generator
After 3 weeks the supplier is sending me a new rotor, but the fact remains this is the second rotor that has self destructed. So now I am afraid to run it again after i install the new rotor coming until I can find some answers. I find it very funny that Cummins agreed to send a new rotor no questions asked and didn't request that i return the old one396Views0likes0CommentsOnan 4ky Generator
I have a Onan 4ky generator on my RV, I had to replace the rotor because the last one self destructed. I installed a new one inspected and vaccumed the entire generator tray and checked the clearance to the stator everything looked great. I reinstalled the generator and ran it with the AC on for the load. It ran great for exactly one hour and then shut down. I removed the cover and noticed pieces of plastic and a small piece of copper wire in the tray. I removed the generator again and found the new rotor was destroyed. It appears the winding breaks loose from the rotor shaft where it is glued, moves out breaking the plastic winding frames. The plastic then gets caught in the stator breaking the windings. Has anyone else see or heard of this issue ??? These rotors are $500 bucks, i think the supplier is going to replace it under warranty but I need to know what is causing this, defective rotor ??Poor design ??1.8KViews0likes9Comments
