Another good idea! Thank you. I’ve been using a chip remover tool which is essentially some big tweezers with bent ends, but I’m definitely hooking under the bearing as I do it. This causes me to pull the entire “assembly” off (stack, bearing and o-ring). It’s ok. I mean, it’s not a big deal to put them back on, but I haven’t spent a lot of time talking yoyo maintenance. It’s neat to see how other people do things or don’t do things. Sorry to derail the thread, though.
