What size bearing splitter are you using in this video? By the way thank you for you time in making this very informative video.

[@jonathanbrazeau970]

when you have a series of pistons, so a crankshaft with a few different loabs and wrist pins, if the journals are using actually bearings, like in a multiple cylinder motorcycle engine... if the wrist pins are just round cylinders and pressed into place, how does everything stay aligned and indexed correctly?

[@elmeradams8781]

They are pressed together. The outside of the bearing spins. The inside doesn't.
If I understand your question

[@shimmershine1585]

Where can I get those bearings in the middle of the crank?

[@5StarPWC]

wsm or sbt has them

[@jenniferlynnmathewsmojaveh5843]

I have a crank that I'd like to replace all bearings on because a piston broke and there is probably metal in those bearings. Are you a business? Can I send my crankshaft to you for repair?@@5StarPWC
