Bill, I do not see the slots :( Would these be on the armature shaft nearest the fan or the copper windings?? |

They are on the windings. You know how all those metal segments cover the windings? There are probably twenty of them. Each of the segments has about a 1/8 inch gap between them. Anyone of those gaps is where the tool is slid into. The photo is a Rainbow armature, but a Kirby armature is the same. When I rebuilt my first Kirby in that series, I had the same problem! I had the tool, but I had no clue about how to use it. I'd love to say that it was great skill and a keen mechanical mind that led to the discovery. But it was purely by accident! LOL! Hope this helps! |

I never even removed the field from the plastic housing. Thats the odd thing indeed. I just cant figure it out, everything goes into place, the armature just cannot spin without hitting the copper winding... |

Derek, I think I see your problem from the first photo. Somehow, the fan got pushed down too far. It's too close to the spacer on the windings. It needs to be further up the shaft about 1/4 inch or more. I don't think I remember seeing an Omega armature quite like that. The ones I've seen have etchings machined into the armature and the fan sits on those etchings. I think they are there in order to create friction to hold the fan in place. In fact, it looks like the fan made scratches in the shaft when it was somehow forced down toward the windings. You might try taking long punch pin or screw driver and place it on the underside of the fan to force it up. |

WOW!!! What a difference! Thanks for the insight my friend! I will let you know how it turns out. |

Oh yeah, I'm sure you know this. But it helps to put the armature shaft in a vice in order to stabilize it. Just be sure to wrap it in a cloth to prevent gouges. Gouges will cause it to run off balance and that will ruin the motor field (and the armature too). Also, be careful not to bend the fan. I think if you butt the screwdriver against the riser on the bottom of the fan, you'll be safe. |

Derek, you might try taking the fan completely off and then installing one or two tolerance rings onto the armature down by the spacer (depending on how much tolerance you need) and then putting the fan back on. A tolerance ring is light weight and I think it will keep the fan from riding down the armature. The grooves that are machined into most Kirby armatures essentially function as a tolerance ring. But you can also put them on after the fact. I've included a link so you can see what they look like. I think teflon tape might work too if you could be sure that it would stay adhered to the armature. If you do use the tape, you might want to wipe the armature down with some acetone or MEK to make certain that oil and other residue is cleaned off. CLICK HERE TO GO TO eurekastar's LINK |

Thanks for the heads up Bill. The Omega should be good to go very soon! |
