removing sealed bearings

(1/1)

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?

perry:
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  :daumenhoch:

Glynnyboy:
cheers for that i'll get looking through my tool box.

What Perry said   :daumenhoch:


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
