Screw rusted; cannot remove

I was given an older Rainbow, vintage 1986, that I'm hoping to be able to use. However, the screw cap that holds the filter bowl (or whatever that slotted plastic protector is called) on is rusted. So, when I turn the screw cap, the piece (bolt?) beneath turns, also. I have sprayed it liberally many times with Rust-Ez and Wd40, but I cannot grab anything stable to help force the two pieces apart (because the filter blocks the way). I even whacked the cap with a hammer, hoping to JOLT it into submission... to no avail! I then removed the 4 screws from the bottom, but decided I probably can't remove the bottom because of the filter being screwed on! So, I tried to pry the top from the bottom area (where the multiple slots/tabs are between the two pieces), but I'm afraid I'll break it! Is there an easy trick to making the top and bottom pop apart (assuming I can resolve my problem by coming from the top)? What do I do? How can I remove this screw cap so I can clean this machine, and make it work for me? Any help you can provide in removing this screw cap would be greatly appreciated. Thanks! Signed, Screwed Up

Nut, is attached to the motor ( armature) the plastic housing is a cheap replacement but the nut that is attached to the motor is not, crack the plastic housing (looks kinda grayish right) AND ATTACH A VICE TO ONE AND A NEEDLE VICE TO THE LOWER THIS SHOULD WORK,,,,,DO NOT STRIP ANYTHING DONT WORRY ABOUT THE BOLT IT IS A CHEAP REPLACEMENT TO

Re: screw rusted; cannot remove

Ok for one, once you remove the screw hopefully you havent damaged the armature, which is the most important part,,,,1. get vice grips 2. try to get something to lock the sides down, ......question first, do you know if it works, if it does why are you taking the screw off, also if it doesnt its unfortunately probaly not worth fixing, if you need parts off of it just crush the side open..... if you come across another unit that has a screw loose, use silicon on the bolt and screw it will help keep it from rusting...

How do you replace the top shell of the Rainbow D series? It doesn't look like the wires can be disconnected without cutting.

To replace the top cap of a D4 Rainbow vacuum:

Remove the separator.
Remove the 4 screws on the bottom.
Pull the bottom off around the foam tank gasket.
Remove the next 4 screws.
Carefully pull the wiring up through the middle section wire hole.
Remove the top cap 4 screws.
On the bottom of the switch there are 4 fingers, one on each corner.
Push the fingers towards the center of the switch and push the switch through the rectangular hole
Pull the wire through the middle section and the top cap to give you as much loose wire as possible.
On the long sides of the switch near the wires are 2 small round holes with small semicircular tabs pushed through the sides of the switch assembly. These tabs hold the wire assembly in the bottom of the switch. Very carefully push a jewelers screwdriver between the switch body and the wire assembly on each side simultaneously to release the tabs and pull the wire assembly from the switch body. BE VERY CAREFUL. Do not pull the wires hard. The wires are held in the wire assembly by small friction clips. They are not soldered or attached except by the friction clips. These friction clips fall out very easily. The twist in the wires alone will pull them out of the friction clips. So hold onto the wires in such a way that they cannot twist free. If you loose a wire or two, you will have to push them back in and reset the friction clips. This was a challenge of dexterity. During factory assembly, The wires were probably pushed one at a time into the bottom of the completed assembly. You could record the position of each wire and replace them as the factory did. This was the most difficult step as the switch came apart very quickly and without warning and the wires very nearly separated from the switch assembly.
Remove the old top cap from the wires and replace it with the new top cap. A 3rd hand may come in handy.
Push the wiring assembly back into the switch body the same way it came out.
Push the switch back into the top cap.
Reassemble the vacuum.

How do I change the hepafilter on my Rainbow E series? Thanks

You have to remove rear cover (on the opposite side than the intake is) There are 2 kinds of HEPA and 2 kinds of filter covers:

HEPA encased in black plastic - on the bottom of the unit you will see two latches and you can use a flat screw driver release them and filter cover just pops out.

HEPA older style (white filter with black plastic frame) - there are 2 Phillips screws on the bottom of the unit and 2 more under the cord caddy. Use flat screw driver to remove the cord caddy (put it in between the housing and the caddy and it would come off)

If you need filters - they are HERE.
Good Luck

Power Switch

This is not that hard:
1. - remove gasket (it is glued so you may end up damaging it)
2. - remove 4 screws holding baffle
3. - under it you will see 4 more screws holding cap
4. - Four more screws and you will remove cap cover
5. - cut the cable tie, make a note how wires are connected, use flat screw driver to press on the latches holding the switch in while pushing onto the switch OUT. Tension will not let the latches pop back in.

6. - reassemble in the reverse order.
Switch - if you have old style switch installed you will need to push something into each hole next to the wires to release them. There is a cooper lip in each hole that you have to bend a bit to release each wire. Installing new style switch (with 4 wires) - attach one power cord wire to one blue switch wire and another to another blue switch wire. Attach one motor and one power nozzle cord receptacle wire to one black and another pair to another black wire.
Gasket - use weatherstripping glue to glue motor gasket back (you can get some in almost any automotive store)
Need parts - visit our store HERE.

No diagrams - sorry. It is Rexair, Inc. intellectual property and we can not use them...

My Rainbow SE vacuum was working fine until I ran over the edge of a rug and it went in to the nozzle. I immediately switched the vacuum off and proceeded to move the rug. When I tried to turn the Rainbow...

hello lilbutmunch1,
The brush is motor/belt driven so you probably either broke the belt or it shifted off the motor or brush shaft. I suggest you unplug it,flip it over and look for screws that hold the baseplate together.. remove those screws and seperate the baseplate to gain access to the brush and motor head. Once open, it should be fairly obvious what the problem is.. a broken belt, a belt that has shifted or the brush won't spin freely due to an obstruction. Hope this helps..

Having problems removing separator on Rainbow Vacuum....

Not a good sign. If your Rainbow is SE or newer - separator should not spin freely.

Some may recommend torch but I am afraid that you may end up melting some plastic parts so be careful. I'd say put a wrench on the nut, hold the separator and press it towards the motor (thus holding the armature as much as it is still possible) and then hit the wrench that is on the nut with another one - create momentum.

If this does not work - you can use pliers to destroy the separator completely so you would gain access to another nut that is under the separator so you can hold the armature with another wrench.

I can not guarantee 100% that you will succeed as sometimes those nuts are so rusted that you have to have the armature held in a vise.We usually disassemble the motor so we can hold the armature by hand or in a vise but if you do not want to go that far into the motor - use described above method - maybe it will work.

Changing the two HEPA filters in the Rainbow E Series.

Plastic thing is fine. it probably has "e" in the middle...
To replace the motor filter you would have to remove cap. You have to get clear plastic lenses off the unit (you will need small flat screwdriver to release latches on the top of the lenses). Under those you will find a total of 4 or 6 screws. They hold the cap onto the main body. Filter is under the cap. See HERE if you need the filter.

Good Luck

There a number of screws that you have to get out. Maybe a screw extractor may work, last resort would be to drill the heads off of the screws, then after the plate is off, remove what is left of the screws.

Take off water tank, remove the screws to separate the top from the bottom, take out the screws inside the top and take out the plastic shell and the switch will be there.
