Guys
I have a seized bearing in an alloy hub. Is there any way to remove it without destroying the hub completely?

Thanks

ummm, maybe you could heat up the alloy hub enough so that the bearing falls out of the hub, like with a engine bearing

hope this help a bit

I have to agree with Pro-4...the aluminum will expand more then the steel bearing and will drop out easily. for every 150*f temperture increase, steel will exapnd .001" per inch and aluminum will expand around .00225" per inch.

Good luck.

I would just stick a saudering iron in there and then it should pop right out.

you could arrange special clamp with these ingredients:
long M4 screw (6cm+) and M4 nut + 4 mm drilled FRP / aluminum 3 mm plate (around 4 x 4 cm) + suitable strong plastic/pvc tube or pipe (about 4 cm length with 10 mm internal diameter)

1. put the head of M4 screw (preferably with socket head) behind the bearing
2. attach the plastic tube or pipe perpendicular to outer hub surface carefully
ensure bearing can go through it
3. put the drilled FRP / aluminum plate on top of it through M4 screw
4. put the M4 nut on top of it, then turn clockwise
5. Hold the socket head (bearing) with suitable Hex key
6. Turn the M4 nut clockwise with M4 mm wrech (tamiya wheel wrench works perfectly)
7. voila.. bearing ejected nicely.. hub stays cool unscathed
sorry for my english,
