Jack,

I'm with you. I'm thinking about just radiusing the new bearings as much as the old ones are now. What I don't want is that reduced oil pressure if there is too much clearance on the first few runs. Yes I'll lose potentially 5% of bearing material, but I doubt this is significant.

I'm then going to tell the owner that he needs to start looking into a new crank. This is a 90 hour motor, so it'll give him some time to find a new one, and there won't be a ton of hours on the main bearings before a refresh is needed.


...and as I might have mentioned, the thrust bearing is showing copper on the shoulder surfaces, further strengthening the lateral end-play theory.
