Rainbow D2 Chrome Dome

I've worked on thousands of Chrome Domes in my lifetime. First. you'll need a hammer and a good Phillips screwdriver. Hit the driver very hard while in the screw to knock it loose and drive it deeper in.

Once the eight screws are out, you can remove the flange. Then, you'll need to hit the spider nut with the hammer on each 'corner'. Use two sockets, one on the top fan nut and one on the spider nut. They turn in opposite directions. Don't remove the spider nut until last.

First, remove the fan nut, the fan clips, and then the fans and spacers. You'll come eventually to the bearing plate. It's held on with four screws. Before you remove them, remove the carbon brushes AND holders. Then, remove the bearing plate screws and plate.

NOW remove the spider nut. There's a cross section to the armature where you can plate a straight screwdriver longways to hold it. Once the spider nut is off, the armature removes by lifting UP. You now have a motor housing with the lower bearing as well as the field coil. You will remove the field coil by removing the two screws and hitting (tapping) the housing against the bench until the field coil comes out. Remove the four bearing flange screws and remove the lower bearing. Now you are ready to wash everything (except carbons and bearings).

Checkrate/Likes I found a Rainbow D2 Chrome Dome the thrift shop the other day and it seems to have followed me home. I guess it shouldn't be any surprise that a 50 year old water vacuum is going to prove difficult to take apart but anyways I guess I need a challange. Two questions so far, the screws that hold the motor in have pretty much turned to mush, any tips for getting these out. And how does the spider come off? I assume you turn the nut but what way does it unscrew and is there anything else that has to come off. That nut is also welded on pretty good. Thanks Cameron.

Checkrate/Likes 1 *Hardest thing* To work on ever devised...But Tom and Clay like to work on them!!I have seen Clay take one apart in about ten minutes, I always used a impact driver, I did Rainbow service for a while, I like the machine, but would do almost anything to keep from working on one!
