Re: Lesser of two evils..cracked main babbit or used replacement?
By fitting, put the crank in and spin. High spots should be shiny chect fit. Bit of an art to know what to do next, but if the crank turns tight and the clearance if good then you need to bring down high spots. I am not very experienced at it so I do not dare go further. Obviously you will playing with shims at the same time to get the fit.
FWIW there are special babbitt scraping tools. You may have to make due with a knife edge.
