I've got a Star Trac ST2000 treadmill, pretty old but came from a low-use physical therapy clinic and still works great. Last years, our basement flooded and the treadmill was sitting in 1-2 feet of water for several hours. We were thrilled that everything still worked once it had been dried out... but the rear roller eventually seized up, I'm sure from water getting into the bearings & creating rust.
So now, I have the rear roller removed and I'm trying to disassemble it to replace the bearings. Youtube videos make it look pretty easy. But this Star Trac roller has black plastic covers on either end of the cylinder that hide the bearings, and for the life of me I cannot figure out how to get those covers off. Does anyone know? And/or does this cover have a purpose other than cosmetics? If not, I could cut it out with a Dremel or something else.
I really would like to repair this roller, since it's the only problem with the unit and I cannot find any complete replacements. I'd also be curious to know if roller from other treadmill brands/models would be compatible replacements. Thanks!
