I just swapped my middle reel with a different reel I had.
It's so much quieter now!
I swapped the baskets to see if I could pinpoint the problem noise.
It was still fairly quiet...
I'm convinced it's nothing electrical over here, just one old stepper motor.
The sound emanates from the bearings inside the stepper motor and
not from the baskets or the strips.
However, removing the strips makes it a touch quieter meaning
that the strip is acting like a amplifying sound board.
My strip had sticky adhesive to join the ends together like so many strips I have.
Nothing different there.
When I put a short strip of scotch tape on it, there was no change in sound -
the sticky adhesive is enough to do the job.
Swapping the noisy reel to another reel onboard didn't do anything so
I know now that the sound was coming from that one bad stepper motor bearing.
The same may or may not be true for your reels daddy2yea?
I'm gonna shop around for brand new stepper motors or
take one apart to see if I can replace the bearings.

 Hail Hail Hail Hail Hail Hail Hail Hail Hail Hail Hail

Stayout - I'm real anal when It comes to sound and looks of my machine.   If you could find replacement motors that would run silent, I would vote to elevate you to God status on the boards.

I removed the basket from my noisy reel.
Pulled off the 8-pin plug and removed the 4 nuts that secure the motor to the reel plate.
One nut of the 4 secures the green ground wire from the motor.
I then pulled the stepper motor apart and rotated the bearings by hand...they are rough!
That's where the noise comes from!
The stepping motor is made by "Teco Electric & Machine Co. LTD. based in Taiwan.
Type:  4H5618X0606
Degrees: 1.8
Volts: 16Vdc
Amps: 0.4
There are 2 bearings on the motor shaft.
The bearings have writing stamped on them>>

NMB 627Z Thailand

I will do a search for new bearings, order some, replace and see how this baby works now!

OK I'm still going to check the volts as per a69mopar.  But I do have a stepper motor with a bad bearing in it(the #2 reel that talked about earlier that I replaced with another reel) and as luck would have it I have a large bearing distributor right here in town. SO thanks for the head up that the bearings are replaceable.   Mike

PS how about new video of the machine now. also for me Swapping the noisy reel to another reel onboard  jush cause the noisy reel to run quiet and the quiet reel to be noisy  like I said whatever pluged in to the 4TH spot.

Hey!
I just got this email from one seller>>>


Mark-

The bearing you mention is probably ZZ – two shields. It shouldn’t be duplexed.

We have he 627ZZ in stock $6.50 EA

Now, I wonder what he meant by "shouldn't be duplexed"....hmm?

Here's a couple of pics of the bearing inside the stepper motor casing...

does that look like a part that can be replaced?  What type of bolt is that in the center?

That's the one!!!!
It's exactly like mine....the 627ZZ is cross-referenced to 627Z.
All that the ZZ means is that it has a dust cover...
I'm ordering some and I'll let you guys know how it works!

There's no "bolt" JDK, only the shaft in the middle...
I have a little gear puller by the way...
I believe you place the shaft in the freezer for a couple of hours,
heat up the bearing a touch with a blowtorch and slip it onto the shaft.
When both parts are at room temperature, they will be snug as a bug in the rug.
At least that's how I put my bearings back in my motor on a motorcross bike...

Duplex Bearing
     A duplex bearing is a bearing with controlled axial location of faces of inner and outer rings which makes this bearing suitable for mounting in various combinations with one or more bearings controlled in the same manner.

Yes, you could but I don't think you need it because
I was able to pull the bearing off the shaft just by sticking
two flat screwdrivers under the bearing,
turning the screwdrivers a little and the bearing popped right off!
That pin to line up the basket reel is tough to pull out though...
I inserted the pin into a long socket with the shaft resting top of the socket.
With a small hammer, I tapped down on the pin and voila! It came out of the shaft!
Now, I'm able to take the top part of the motor casing off and remove the other bearing as well!

haha! Behold! The bearing near the top of the motor is slightly brownish/dis-colored!
Right where the ball bearings would be under the cover!
That means it's shot! That's where the noise was coming from!
I'm ordering some bearings from that link dadd2yea posted!
I'll get the box of 10pcs. and send you guys what you need.

I think when you get them Marc we'll need a new thread to detail how to do this.  I think I'll need 4 myself.  I would love to have a whisper quiet machine.

Remember, this stepper motor is from your old Bally ProSlot5500...
now, I'm wondering if the Bally6000 has the same motor in the reels?

daddy2yea,
It looks like low TP3,TP4 and TP5 readings to me...
maybe a69mopar will have the schematics drawings to see if those voltages are sufficient. yes
But , I'll bet he may know exactly which components need to be changed/beefed-up to get the correct voltages!

Man good catch -  the whole bracket assembly is completely different.    When I get home tonight I can take my spare reel apart and (with your help lol) see if it's the same.

When I took apart the Bally ProSlot5500 16Vdc, 0.4Amp stepper motor,
I found that the top most bearing was very dis-colored.
I think that it was overheated and is shot !
Time to replace it!
I'll bet that the reel will run much quieter after this replacement...

<a href="http://www.youtube.com/v/nS87vl3BFps&rel=0" target="_blank">http://www.youtube.com/v/nS87vl3BFps&rel=0</a>

Rudy has four of them for sale guys.
These ones are 24Vdc and 0.2 Amps...
Make sure they're the SAME as the ones for your Bally 6000's...>>>

Since I am getting my own Bally S6000 soon, I guess I should check the reels when it is operational. Lets see first if that is the source of the noise..........I'll bet it is! Good one Mark. K++ Wonder (out loud) if there are corresponding parts on IGT stepper motors? maybe we should find out.

I was doing some searching around and
found this very cool video on controlling a stepper motor.
The funny thing now is this:
If you listen to the sound emanating from the second motor
he attaches to the controller board - it will sound like daddy2yea's reel. Weird Eyes
And it really doesn't sound like the bearings are bad...
so what's going on?
Pull the slider bar to about 6:26 seconds and
you'll see what I mean if you've listened to the earlier videos
we posted on the reel sounds.>>>
