I took Fred's advice and put the motor parts through the dishwasher. I did so with a little anxiety. But alas, it all turned out well! I didn't run the main housing parts through the dishwasher. But after seeing Fred's photos in another thread, I feel confident to do that in the future. My hand washing of the main housing wasn't as thorough as the dishwasher would be. But I did use bleach and laundry detergent to make certain it was sanitized. |

Once the motor was reassembled, I thought it would be important to test the motor before putting the entire vacuum together. I did test everything with my multimeter and it checked out OK. But this is the true test. Everything check out OK, so it's now time to move to the next step of the reassembly process. If you need to seat motor brushes, I would think this is the time to do it. But the old brushes were just fine, so I simply reused them. |

Once it got it all reassembled, the last step was to install the gasket onto the motor flange. I just a little weatherstripping adhesive from the automotive department at Walmart. I think a little bit of that stuff goes a long way. It's all clamped down to the water basin right now to allow the adhesive to get set. |

Fred, I think the slinger ring serves a dual purpose (and this is a little bit of guess work on my part). First, it helps to hold the bottom bearing in place once the retaining clip is installed. And second, it's designed to hold grease. I believe it is called a slinger ring because it's designed to "sling" grease onto the bearing face and armature shaft. The lower bearing used today is double sealed. But I think the grease is used as a precaution against moisture. It probably is overkill today because of improved bearing design. I'm guessing the grease is not really necessary (if the machine is properly maintained). Plus, when the spider is installed, it is seated into the slinger ringer thus providing an additional seal. The main reason I used the grease is because the guy who owns the local vacuum shop told me that's what he does. LOL! I have a spider on another D4 that's like yours. I think that is an early design for the D4. I kind of wonder if it's design is intended to concentrate airflow. Not sure! Can't wait to see yours when it's all done! |

Wow! This is very interesting, I'm amazed that you can put all these thing in the dishwasher. You did a beautiful job and the SE looks very happy. |

Wow, you guys just amaze me with these breakdown pictures. Absolutely amazing. Fred you have a really nice Rainbow, that will give you years of service. I still have mine. If you clean the separator after each use and wipe the flange, that is all the mntc it will need for a very long time. I told Ken Bashford on Friday, when I was ordering the longer 14ft hose, that he needed to read the forum and see all the interest generated about the newest Rainbow. He said he had read some of it, but not all. I would have loved to have seen his demonstration in Texas....
Anyway goodluck with your Rainbow, I am sure you will like it alot. Sincerely, Bud Mattingly PR-21 |

Fred's question about the "slinger ring" piqued my curiosity, so I did a little research using Google. First, I found that they are used on propeller shafts in order to "sling" antifreeze onto the shaft. I also found that they are used in electric motors and generators to sling oil onto the bearings. I guess that would include the armature shaft. Looking at Rainbow schematics that I've found online, the part dates all the way back to the Model D. It wouldn't surprise me if it was utilized on earlier models too. So my guess is that back in the day when open bearings were used, it acted as a bearing seal and would also provide additional lubrication to the bearings somehow. Again, it's just a pure guess. However, with the use of double sealed bearings, it may be a redundant item. Or it may just serve ONE purpose today and that is to help hold the lower bearing in place. It makes me think of the finger spring in a Kirby motor. Early on, it was needed to hold the bearing seal in place when Kirby was using open face bearings. But with the move to sealed bearings, I wonder if it is even needed. I don't know if it's found on the G series motors, but it was being used all the up through the Tradition. I wish I knew someone with a Rainbow service manual. That would explain it for sure, because my guesses are probably way off mark! |
