I was cleaning up a trackball today, and wanted to know if these indentations in the rollers are normal, or if that's 25 years of wear and tear that has slowly worn away at the metal.
It's normal, I have a wico that looks the same. Bob roberts sells the rebuild kits, but I think he is out of stock of the wico 3" last time I checked. eBay has the 3" wico rollers and bearing kit for $25 I believe.
Thanks, my question wasn't worded well anyways. I'll order one of the kits from ebay and get it rolling smooth again. I'm just surprised the metal wore away that much...It's not as noticeable in the pics, but it's a fairly deep tread the ball has worn into the metal.
