- That should be less effective than making the hole slightly undersize
- and assembling it with the case heated and the bearing chilled. That is,
- unless the bearing race is knurled or "spined" like Harleys Evo engine
- cylinder liners. In that case, the aluminum might bond to the iregularities
- and stick better than a "shrink" fit. Anyway, if the bearing seizes (maybe
- what happened to yours), a shrink fit will cause less damage to the case
- than casting the races in, so you may be better off than stock if you fix
- it this way.
