From good quality tool stores, you can get, telescopic extendible=20
extractor with exceptionally strong magnet on the end.

Before doing any serious disassembly or other operations, go get one of=20
these tools and try. May or may not work, but at least try.

Don't get one from a cheap shop, seek out high quality, the magnet is=20
better.

You only need a sniff of iron in the bearing, and the strongest magnet=20
may be enough to help out, you won't know if you don't try!

Good luck!
