Yes, the next move I’d definitely splitting the case. And yes, crank bearings would be too easy to pass up. What I’m trying to figure out is whether I need to replace the crank and rod assembly. Are the rod needle bearings very susceptible to debris damage as compared to a conventional babbitt rod bearing (that is very sensitive to debris).

When bottom ends give up what usually happens? Are we talking broken crank/rod (and killing the case) or a nondestructive seizing of the rod bearing?

Just trying to get a feel for what I’m up against cost wise and risk wise.

 

Thanks.

Jimmy
