removing sealed bearings

[Glynnyboy]

just thought i would ask before a bit of elbow grease goes possibley where it shouldn't. I am stripping a suntour rear hub to send for re anodizing. Got the axle out had a quick poke and prod with a screw driver caused no damage. Anybody got any tips or advice before it's time to go medievil on it raising the damage risk?

id tap them out from inside with ideally a proper panel beating flat punch but anything long/thin and with as blunt an end as possible

its a hassle replacing the seal if you damage it

dont be heavy handed and for instance go 12 oclock , 6 oclock , 3 oclock , 9 oclock and repeat

you need to tap it out square so it doesnt damage the hub

What Perry said   


It's a good fit, so it'll require drifting out with something decent. Follow the 12 o'clock, 6 o'clock rule and there's no need to hit it hard. You'll feel it start to move then it'll just be series of 'polite' taps to pop em out   

It's worth buying a couple of good punches, one with about a 6-8mm flat head and one around half that size. They'll do most jobs for ya

to save money grind an old screwdriver head off flat

thats the word " drift " memory like a sive lol

tap it at the very edge not the centre of the bearing , ive seen a few sealed bottom bracket bearings destroyed because people hit the inner of the bearing and they dont like that kind of side load so shatter
