I was chasing the other night and a pinwheel locked up. I yanked it loose and periodically stopped the back-end to add grease to the ring tube, but the next night it locked up again. I haven't done any maintenance to an elevator wheel before. All I know is they weigh about as much as my car. Does the ring tube ride on bearings? How do I access them to replace them? I'm on my way to the center right now to get the manual, but I don't recall it contained this procedure. Thanks, guys.
