The bearing will knock out with an appropriate drift . If you heated it in an oven
( when your missus isn't around ) , it might shift easier . I'm guessing it's for a
DT1 B , if so the bearing is a 6204 . I'd use a double rubber seal example .
They are readily available at bearing suppliers ( SKF , SAECO , NTN ) .

That's probably fine . I've always done them cold myself .
Some people heat heat engine cases when installing main bearings / cranks .
I would guess a similar temperature would work . Hopefully someone else will comment .
