I don't know how loud your 'squeel' is, though here's my experience with WCS94:

WCS94 was one of my first pins. My initial impression of the spinning soccer ball noise was that the gears were disintegrating and that I'd need to replace the motor or gearbox mechanism.

I went ahead and ordered a new mechanism and installed it. Before putting the platform on the spindle, I tested the motor. Ran fine. Nice and quiet. I then added the metal disc and tightened it with the set screw. Again, a power-up resulted in a nice and quiet rotation.

Finally, I added the rubber 'ball' and it sounded just like what I started with.

In the end, and after comparing my WCS94 to others in the area, I learned that the spinning soccer ball is just plain noisy.

Sounds like you might have some play or a gear missing a tooth in the gearbox.

Or, PM me and I'll cut you a deal on my spare motor.

I had a squeal on my Motor for the cannons on my STTNG

I gave 1 drop of 3in1 oil in there never happened again

maybe try that ?? Cheaper then a new motor

Where you able to diagnose and resolve the problem? I just picked up my WCS and I find the motor/gears to be a little noisy. I have a lot of work to do on the pin but this is one of the things I will be working on soon.

I had the exact same problem, now my motor burned out. Ordered a new one. Hopefully will work again. Good luck with yours!

I am now experiencing the same problem. Once the wheel/ball gets up to speed it is quiet, but sometimes there is too much drag for it to get up to speed.

I dropped the motor out of the gearbox by two inches and then fired it all back up. Still had the squeal, so I know it is the motor. Unfortunately they don't see the motor separately. Ebay has the replacement for $75 while online shop has it for $150.

Does anyone know where I could just get the motor as it cannot be that complicated.

Let me know. For now I just unplugged the motor.

Found replacement on Ebay and installed. All good now.

Could you share the listing or the part number / specs that let you find a replacement motor?

Marco has the Ball Motor in stock now:

I have an issue with the spinning motor making too much noise and have a new motor/ball from Marco on order that should show up tonight. I'll have results in the main WCS94 owner thread later this week as to whether or not it does anything about the whining sound.

I fixed my noisy soccer ball motor for 5$ and it is a job you can do in 5 minutes.

I had purchased a replacement motor from Marco supplies, and to be honest it was even louder than the old one... MUCH louder. It sounded like a remote control electric car was 5 inches from my ear every time it turned on... I wonder what their return policy is.

In any case, before I reinstalled the old one, I took it apart and saw that there was 25 years of gunk in there. After some research, I cleaned the motor with a paper towel and squirted in some Lithium Grease (5$ at Home Depot in the Automotive Section) and hooked it back up. It is MUCH quieter. You can still hear it, but it is not nearly as loud, spins up faster, and continues to spin a little even after the motor stops sometimes.

If you wanted to do this yourself, you can do it without having to solder anything and by only removing 2 screws. If you look at the motor, it separates from the gearbox with 2 flathead screws. If you remove those, the motor will pop out leaving the gearbox. As you can see from my photo it was filthy. I gently wiped it with a paper towel and squirted in the lithium grease. Make sure you do not lose the little black O ring. The whole process should take maybe 5 minutes.

I think the WCS noisy ball has a couple causes, but after a lengthy investigation into my identical issue (squeal) I can say with absolute confidence that the specific one this thread was started for is the bottom pin of the motor rubbing against the surrounding nylon.

So remove the motor (2 screws), put a drop of tri-flow (or similar lubricant) on that pin and allow it to seep in there via gravity while manually spinning the top gear.

While you have the motor off, you can add some white lithium grease to the gearbox and your soccer ball should be good to go for a long time
