Interesting & won't pick holes in it but ya do what you have to with the gear you have, & my rebuilding leaves a lot to be desired haha but not had a failure--yet. Not sure how the first one or both set the side clearance or if the pin comes through to touch the block thingy on both sides exact for clearance but doubt it. Then if that's the case the bearing must come up to a step or to give clearance to the pin. i'll have another look.
