I have one fb460v apart. Someone removed all labels, so I can't determine the specific model. The crank has "37" on one side, and "J" on the other. The crank is worn. I have another fb460v. It has a label: CS-02. I haven't disassembled it yet. Will the crank in the second work in the first? Are the cranks the same in the 30-50 different variations? Is there any way to determine which model engine I have from the letters on the crank? Thanks. Rick
