Rainbow D3 vibrating badly

[universaldave1]

I'm hoping some Rainbow people will be able to help me on this one. I really like using my Rainbow D3 that I got at the VCCC convention, and after a good cleaning, and a new hose, it turned out pretty well. The only problem is that it sounds like it could blow up when in use. The motor shakes so badly that I'm scared to use it. If I put my hand on the top housing, it quiets it down significantly, but obviously, I can't do that when I vacuum. I tried tightening a few screws on the underside, but that didn't help. I'm not too well versed fixing Rainbows, as some of you may know.

A common problem...

The fans have dirt in them throwing them out of balance. it needs a good tearing down and cleaning. Rainbows have this problem as they age. might try a new separator. the hole in them sometimes wallows out with age and makes them vibrate.

Seems like it's

Time for a cleaning and rebuild.

Try running it, WITHOUT water, with the separator off. Ive seen that cause your problem before, but if it still sounds awful, the motor needs a good rebuild, and possibly new bearings.

I took the machine to a Rainbow dealership today, and they said that the lower bearing is bad and that they do not repair D3's anymore. So...

Dont believe that..

There are plenty of guys here who can fix it with no problem!

Thanks for the offer,

But I'm in a finacial hole right now. I can't even afford supper tonight, much less shipping a Rainbow halfway across the country.

 

[kenkart]

Ive been there too..

Just hold onto it and I'm sure one of our Rainbow experts will be glad to help you when you can. I haven't worked on one in years and no one could pay me enough!LOL

 

[universaldave1]

Oh yeah,

I know what you mean about that. I refuse to tear into any Rainbow older than the E2 one speed. Those are pretty easy. But the older ones are ridiculous! I tore up my old chrome dome because I wasn't paying attention and forgot how it went.

I at least made the D3 look better. I took its helmet off and cleaned all the fine dirt out, so now it's clean and clear at least.
