Reply To: Crankshaft Roll Pins

Thanks everyone. I understand about the “bumps” now.  But, that brass cup only holds the spring and if it spins with the crankshaft the spring above it can’t spin. There is no connection aside from some oily friction and the spring isn’t attached to the stainless washer and cork seal above that so they wouldn’t spin. Upward pressure makes sense for a better seal overall
