Hi, I need to replace the stator and rotor in my HDKAJ 7500 gen set. I took it out and found that the rotor has lost 2 magnets. The stator is also damaged and cannot be repaired, in my area anyway.Any suggestion for repair or replace beside Onan direct for a better price? I was quoted 1200 for the stator and 621 for the rotor.Thanks

That's a good price, most folks have paid a lot more. I got about that number ten years ago with dealer assist on pricing. USD

I got another price from Yakima generator, $557 free shipping for the rotor. For the stator, there is a place where they rewind it for $750, Eurton Electric, but don't know shipping fees yet, and it is very heavy, probably need a wooden box. There is a good difference in price, but from Onan, it is new and the did have an upgrade on both parts.

I had mine done during a 1000 hour service at Cummins Onan service center. $2800 for service and stator/rotor replacement.

I took my stator to two really good rewind shops and both said Onan does something special...don't remember what, but they could not guarantee it. Lots of work if you have to pull it again, BUT you will be more experienced. :)

I have a zillion pictures of dismantling that generator, all the way down to that rotor and stator. I got real lucky on my replacement rotor. I found it on ebay. It was out of an 8KW Onan. It's the same exact rotor. I got it for $200 which, included shipping. As for the stator, well, that's another story. I looked all over the place and finally found one for $1,150. I bit the bullet and bought it. I did the complete tear-down and install. Our gen is on a sliding tray which, makes this sort of repair CONSIDERABLY easier. Since the loss of Photobucket, I've not be able to post any pics on here or, otherwise, I'd show you a ton of photos that might help in your process. That is, if you're the one that's gonna be doing the work. If not, no biggie. Any questions, PM me if you'd like. Scott
