yyf bearings and spacers

why is it so difficult to get thease 2 things apart to change? i dont have a problem getting my fhz bearing on and off because its really not connected at all! whats the logic behind this?

Its just that they are tight. Another problem I see is that the metals the spacers are made is very soft. When I was taking out my protostar´s bearing the spacers got all scratched, dentented and got marks really easily.

The logic is that this way, bearings will sit tightly on the seat.

Sometimes, yoyo’s can have vibe from looser sitting in the bearing seat.
This is just a guarantee that YYF throws won’t have that.

I see. Thanks for the replies!
