Did you get this project done? The freezer and hair dryer trick is, yes, clever and effective, kudos to SvenMN, and when both are at ambient temperature should give a very secure fit; similar techniques are used to place much bigger bearings into precision CNC machines. Red locktite seems a bit overkill, I'm about to do the same replacement and will not be using any adhesive. I will use a small / medium bearing puller to get both sides into the BB, with a 5/8" washer to distribute force to both bearing races. I also won't use the circlips. If the spindle shifts in the bearings, I'll re-mount using just a trace of blue vibra tite on the bearing IDs. It should be good for 20+ years or until the spindle cracks.
