The bearing OD should be a press fit. I have no doubt Modern built it that way. Once you presss it into the crank it is not going anywhere — no LocktiteŽ required. The bronze insert will provide the support the input shaft needs w/o the danger of a steel to steel seizure, which is the proper way to design the bearing.
The bearing looks to be everything you need. Just be sure it is a press fit. Before installing it clean the bearing register in the back of the crank, clean the bearing OD, apply a light coat of
oil and press the assembly together. You will be good to go.
