I concur.

1mm=.03937"
The crankshaft will have a hardness of ~Rc 40 in the pilot bore.
The bearing outer race will have a hardness of ~Rc 64.
A very tight interference fit at a diameter of 35mm would be .002".

At an interference of almost .040", there is absolutely no way that the bearing could be inserted, even with a large press, while still intact. The outer race would be shattered.
