Maybe this is a silly question, but in the guide to the 32-day clock, it is indicated that if you have 623RS bearings, the rubber seals should be removed.
Why is this? Do I just stick a pin into it and try and pull it out?
That is a perfect video showing the exact steps I use to clean the bearings. I use a safety pin to pull the seals. Thanks for posting it.
He must be using a cut off ball needle. Mine have a blocked tip and holes on the sides. I use a larger nozzle, but try not to spin the bearings too fast. I have heard reports of bearings exploding when blowing on them with high pressure air.
OK, I opened them up and then wondered how the heck I was supposed to clean them. Then I saw this video:
Is that what you did? Soak them in degreaser and then try and blow them with an air pump through a ball needle?
