I am still using my Genie, with time limits. After cabbing awhile the motor gets hot & I get a scratching, crackling noise out of it. At that point I shut it off & I am done for the night. I generally limit myself on what I work on & turn it off before it gets that hot & the noise starts. What I want to to is replace the bearings in the motor & I am wondering if anybody else has done that & could give me some instructions as how to do it myself. Can't seem to find any information on the net giving me instructions. Thanks - Donnie

Donnie: I replaced the bearings in my bandsaw moter a few years back...........no instructions, just took it apart pulled the bearings, one seemed OK. Took both of them to a bearing company, got two new ones (much better ones) and put the thing back together, and it ran better than when it was new. Bearings are VERY standardized so replacing hem is not a problem, but it helps if you take the old ones to the bearing company. You can also do this on-line by matching the bearings. Woody

Thank you, Woody, doesn't sound so bad. So where is it I go to find bearings? Is it an actual bearing shop that I can find in the phone book?

You would be better off finding a motor repair shop. Bearings wear out and make noise all the time. The noises you describe don't sound like bearings to me. I don't remember if you replaced the capacitor before but I would start there.

My wife picked up a "heating " Genie at an estate sale really cheap, capaciter was out, cost about $5.50 at Graingers. The bearings seem to be somewhat problematic on these machines, easily replaced. Best to get them from a bearing supply [Applied Industrial Technologies, or U.S. Bearing, many others]. The motor shop here will get them from one of these places and mark them up 100%, best to shop it.

Now you tell me! I just spent $30.00 plus on a capacitor. Oh well, it's too late now. I will start with the capacitor & go from there. Right now motor sounds beautiful. Fast, quiet! After I replace the capacitor if I still have problems I will move on the the bearings. Thanks for the info though. That is good to know & I will check out both places for the future. Donnie

Donnie,
I bought my Pixie from Diamond Pacific a couple years ago. Late last year I took the machine into their factory as there was some problems with it. They replaced the bearings for free. I had the time to drive it out to Barstow, but did you try to contact them directly? They are an excellent company to work with.

Yes, I did. I have an older Genie, from the 70's. It was given to me as a used machine that had been sitting for a long time. They suggested that I ship it to them & they would check it out & do whatever needed to be done. I just couldn't afford what that was going to cost me to that, let alone what the shipping would cost. I talking about hundreds of dollars. So I am taking it step by step myself. I can still use it, runs good. But after about 2 hours or so is when it starts to make a crackling noise, when it's hot & very wet. Sounds electrical to me, not like the rolling marble noise noisy bearing would make.

I agree with Donnie above
Cracking noise and wet = a short circuit check the wiring clean the motor up pressure hose the wireing (coils) and get all the dust + crud off
At guess what is happening the dust has covered the whole thing then the moisture gets on the dust then the electricity starts to track, = crackling noise
When a bearing goes it is a continuas noise that eventualy degenerates into a crunch that gets worse
Also the shaft gets more movement on it ? Check the shaft movement when it is Idle ?
Bearing removal will be difficult as it needs a bearing Puller to pull the bearing off the shaft.
There is generally a set of nuts around the motor and thin bolts go right through that you start with to get it apart
Hope this is of help

Jack, the Genie has a totally enclosed double shafted motor. They run hot normally. I recommended a motor shop since the motor is a very expensive OEM motor and I don't know Donnie's mechanical aptitude. Unbolting the motor would be relatively simple. Replacing bearings maybe not so easy. A motor shop can inspect windings, etc. and make repairs as needed A $450 OEM motor is generally worth repairing. From her description the bearings are not the problem but a motor shop could replace if needed. Sometimes it is cheaper to pay for expertise.

Yes, Jack that does help. It gives me better insight into the motor & it makes perfect sense as far as replacing the capacitor, which is the same thing as what John told me. Hopefully the capacitor will be here today. Thank you very much! Donnie

I understood! Got two pictures in my mind - one was a yes & the other a not. Air, not water! I am mechanically inclined, thank God for that. Rather I am capable of doing the motor that is another question. We will tackle that one later, if it is really necessary. Still waiting on the capacitor and I just wish the bottom wasn't warped. Wasn't when I got it, sure is now! Donnie

I agree. Simple motor repairs like cleaning and oiling are usually easy but replacing the bearings in a sealed unit might be tough. I'd say a motor shop would have no problem getting that thing running normally again. Steve

Donnie, the warped base board is a real problem. They use a laminated particle board with a really heavy motor in the center. I've had several customers receive a brand new Genie and have the base board broken in shipment. I suggested they leave the rubber feet off so they can ship with a flat surface but "they have always done it that way". That has nothing to do with yours. Particle board is sawdust and non-water proof glue compressed. While you have the motor off pick up some exterior 3/4" plywood and cut a new base. Cover it with a water proof surface like Formica or even sheet vinyl flooring and it should outlast the machine. A few good coats of an exterior varnish or paint would do pretty well also.

Thanks, John, I was hoping someone would have an answer for that. I wrote the info down & will get what I need to do that while the motor is off!

Hi I have washed electric motor armatures & windings wet many times it dosent matter wet or dry as Long as you Blow them dry with compresses air (I think what makes electric track is damp dust ?) Some times paraffine is the only thing to get the oily crud off or a comercial cleaner I would Stop at taking any electric motor apart to replace the bearings if you havent done it before and you havent the tools eg Bearing pullers and a Press to push the new bearings back on This Rules out most people (Including me now as im retired) As John js Gems says [glow=red,2,300]I recommended a motor shop since the motor is a very expensive OEM motor and I don't know Donnie's mechanical aptitude.[/glow] There is a lot to Motors that can go wrong , even the simple Alignment of the case , shaft Shims to name but 2 Wash out !!? Ok But bearing replacement a Definate NO NO Its job for the Electrical Egineer [glow=red,2,300]Donnie [/glow] Have you no Electric workshops near you ? Re winders ect Im in the country in Uk but there is a electrical engineering workshop only 5 miles away Check them out they would be a lot cheaper and no postage /carrage charges Jack Yorkshire uk

Jack, thank you very much for the info. I don't think there is a motor shop near me. Everyone laughs because I say I have to go to the mainland to get anything seriously done. Forty-five minutes to Homestead maybe I can find a motor shop there other wise it's the big city (Miami) for me & I don't like being in all the traffic & busyness. Capacitor first, if I have to move on to the motor I will find a professional. Donnie

Hi Donnie Well at least your in a warm place ?
check on Electrical Shops and electric rewind shops rather than motor shops
Were in a agricultral area and farmers have a lot of corn elevators = dust = moisture = burnt out motors I suppose
Any way Donnie Have a great Easter
and all the best in sorting out that Motor.
