Yes, I agree with Ross. Assuming the crankshaft journals are in good shape it's an very simple matter to replace the bearing shells.
For those with an interest here's a picture from the 1933/34 Service Letters of the crankpin trueing tool commonly in used in the babbitt bearing era when crankpins were generally not hardened. They worked very well and an advantage with the babbitt is that you only had to turn the crank to whatever dimension was required to true it up and then just size the Babbitt accordingly, so for example, if you need to remove 0.004" to get the journal true, you didn't have to go another 0.006" to get to the next available undersize of bearing shell.
