Morning all
How do I go about removing headset cups from a frame? In a way that is sympathetic to the frame.............
Do I need any special tools?
Many thanks
-
I usually use a drift and smack them out.
-
i normally use a socket set extension bar and a hammer.........a couple of taps and they ping out :daumenhoch:
it's getting the fookers back in thats the tough part!
-
The socket set extension bar is a good idea, do you use the wide end against the cup? My drift is an old valve rod from a motorcycle engine, its hardened and has a flared cup on the end that catches the edge of the cup nicely.

However, if you want to do it properly then get yourself one of these

£17 wasted if you ask me.......the tried and tested hammer and socket bar works a treat.....i would however spend £20 odd quid on a press to fit them into frames....that is money well spent! :daumenhoch:
-
I put cups back in with a home made press, threaded bar from b&q and some flat plates with hole in em. easy peasy.

Me too :) Cups in the freezer overnight, frame in a warm room - next day pop cups in - little tap with me rubber mallet to start 'em off then home made press - consists of 10mm threaded bar - couple of flat plates with hole - couple of washers and 10mm nuts on the other side - couple of spanners - job done :daumenhoch:
As for removal - as above some sort of bar angainst the inner rim of the headset and they should tap out easy with a couple of light knocks from your hammer of choice ;)

big hammer and socket arm for out
big hammer and bits of wood for in.
the key is a good twatting with the hammer, both ways :daumenhoch:

Damn straight! :daumenhoch:

BITD I used JT's method, never had a problem, only gone over to using a home made press as suddenly my frames seem to have aqcuired holy status and a press seemed more worshipful...

Tools for the Job boys.... the removal tool is bloody fantastic, yes the extension socket bar will work but you still chance fookin a cup up with it. the way the tool works it removes it straight rather than a side at a time and never damages cups.
I use a home made press for putting in but bought the Chris King adapters for fitting same, i aint chancing fookin one of those up...

Thanks guys (and girls?)
Sorted. One set of headset cups coming out. :daumenhoch:
