* the bearing outer race is 2mm bigger than case Id.
Wrong bearings. Measure your old ones. I'd contact treats to see if the crank is even correct.
The right crank wrong bearings. Looking for the right size though. They sent me 6004 c-3's
those sound like the right bearings - freeze the bearings and heat the case (edited)

It wont make up 2mm difference. Somethings wrong.
Potential interference fit will be between −0.001 mm and −0.042 mm NOT 2.0 MM (edited)
6004 c-3's Have worked for me several times. Maybe there’s not a 2mm difference.
