Ah, so it's a roller bearing, I thought it was a slide bearing more like a bushing, that sure explains it... So do I have to get to it from inside / front part of the overdrive section?

Where the yoke slides in, yes, there is a bushing. A little farther up the output is a roller bearing. Like on a 727. That is what I'm speaking of.
