Yeah, it's 19 years old bought new and I'm doing the very first main teardown replacing old parts. The bearings actually feel ok. I'll just do a good cleaning of the motor and replace the carbon. Thanks a lot for your insight. |

Pardon my ignorance but they appear to be ok, but I will defer to you to be sure. Thanks for your help. I made sure to keep note to put them back into the original side after cleanup.

There're two screws holding down the lower motor black plastic housing. I closely inspected the lower motor bearing and cleaned the motor housing properly. The bearing rotates quietly.

Surprise! The fan easily slide off clean after a bit of WD40 and waiting for a while. I applied a tiny bit of JB weld upon reinstall of the fan.

We highly advised against removing the fan as those fans ARE NOT meant to come off. Well at this point hopefully your JB weld holds up |

I made the mistake, ONCE, of removing the cooling fan from an E series motor. Thought I had it pressed back on correctly. Customer returned time and again complaining about the motor's thermostat tripping - overheating. Since the fan is pressed on at the factory, the stating torque routed out the hole in the middle of the fan. Glue didn't hold up. Nothing did. I finally had to bite the cost of a brand new motor for the customer.

I called RAINVAC and tech support said JB weld is the factory recommended reinstall process when pressing the fan back in. Will hold up just fine. |

I was looking through my binder of factory service updates to the service manual and I don't see anywhere that Rexair recommends removing the cooling fan from an E-Series machine. Rexair's factory service manual only covers replacing carbon brushes and the revolving fan stage. They don't recommend replacing bearings, armatures, field coils, etc.

WE HIGHLY ADVISED YOU NOT TO...
have the stones to repair your own machine, and maybe learn something in the process. God forbid that happens. What a nasty attitude to have about this. Especially here, a place dedicated to vacuum knowledge. Come on now. You could've just said 'hey it might not stay on now.' The fan looks like aluminum. If it fits loosely back on the shaft, well that's probably because you wiggled it off and ovalled the hole, as opposed to pulling it straight up, which might've proved difficult without a specialized puller tool. I would've held the fan and tapped the shaft through it with a hammer. Still, it's soft aluminum. If the hole is deformed, you can gently squeeze it with some pliers, but don't overdo it. That should do the trick, assuming the JB weld doesn't hold. You can only learn by doing. Vinci, don't let these guys intimidate you. Learning is important, sometimes that comes with mistakes made. Part of life, friend. |

a video on youtube of someone servicing a rainbow......and instead of removing the fans, they took it outside, taped some things up, and turned it on, poured water in the shaft area and the water shot out the back (this is with it running)...He clearly stated in the video that people watching this might get pissed, but someone he knows knowledgeable in rainbows taught him that. I guess pouring water through while it's running somewhat cleans the fans. I don't know. I sure wouldn't do it. But it looked like it worked.

is fairly easy. I performed a refurb on one back in September 2020. Removed and replaced the fan (and bearings) without issues and the owner (Thomas) has been running it since then. I'm saddened that some "experts" don't understand what "press fit" means.
If I wasn't so pressed for time, I also would have used JB Weld as well. Bill |

Yea - I remember you really are against removing the fans at all. I remember you said it makes it worse and it's best to not take the fans off. I remember because a couple of years ago when I dropped my rainbow off at the dealer to have them fix the control board, I left my #. He called me back and I asked if, since he had it there, if he could take the fans off and clean them..He told me they didn't need it. I asked him to do it anyway and he didn't. (LOL) I remember you saying that it's a good thing he didn't because taking the fans off can cause more troubles. The only thing is, I've seen many many people take fans off and clean them and never mention it being an issue.

"Experts"
Exactly. Look. If you're a novice, and everyone's telling you just to buy a new motor... just TRY to fix your old motor. Worst case scenario, you screw it up and need a new motor, which you already needed, so no great loss. And best case, you fix it just fine, and saved yourself the cost of a new motor. And succeed or fail, you learn something in the process, making you a better human being. |
