multi tasking male Posted January 24, 2011 Author Report Share Posted January 24, 2011 just tryed it and the ring wont move at all, wont even come apart because its presed down and pushing up against the bearing, looks like its been overtightened chris Quote Link to comment Share on other sites More sharing options...
forteh Posted January 24, 2011 Report Share Posted January 24, 2011 I would be inclined to use a club hammer or similar rather than a rubber one, you need a sharp shock to break the wedge action of the compression ring; the rubber will absorb alot of that energy.

multi tasking male Posted January 24, 2011 Author Report Share Posted January 24, 2011 i hit it once with a metal hammer but it just bured the edge of it because there crap ashton forks, will try it with a piece of wodd on top so it dosnt mark them chris Quote Link to comment Share on other sites More sharing options...
Theta2 Posted January 24, 2011 Report Share Posted January 24, 2011 I would be inclined to use a club hammer or similar rather than a rubber one, you need a sharp shock to break the wedge action of the compression ring; the rubber will absorb alot of that energy. ^ This. With a pig because of the compression ring getting so tight, you have to twat it quite hard with a solid hammer, careful not to let the loose ball bearings go everywhere though i hit it once with a metal hammer but it just bured the edge of it because there crap ashton forks, will try it with a piece of wodd on top so it dosnt mark them chris If in doubt, twat it harder Always works Quote Link to comment Share on other sites More sharing options...
forteh Posted January 24, 2011 Report Share Posted January 24, 2011 Again the wood will absorb alot of the energy, however you can always file the burrs out If you get a steel plate 5-10mm thick, put an m6 counterbored hole in there to basically create a dummy top cap you dont mind thrashing with a club hammer that would be a better bet.

multi tasking male Posted January 24, 2011 Author Report Share Posted January 24, 2011 have smacked them numurous times with a metal hammer and they havnt moved at all, seems like they have rusted in and wont move but they havnt, no sighns of rust and wont be rusty, kept inside and washed regulary anyone else got any ideas ? would it work to heat the head tube up so it expands and then pull the forks out ? was thinking of spraying it soon anyway haha chris Quote Link to comment Share on other sites More sharing options...
Object Posted January 24, 2011 Report Share Posted January 24, 2011 Once you've removed the stem and all spacers put the topcap back on the forks and do it up tight so that the topcap is hard against the top of the steerer tube. Hold the topotube of the frame firmly in one hand with the frame between your legs so that you can brace it and stop it flapping about. Using your free hand, hit the topcap hard with a metal hammer (A lump hammer is best but you can use a claw hammer if it's all that you have). The only potential damage will be dents in the topcap.

Luke Rainbird Posted January 24, 2011 Report Share Posted January 24, 2011 Chuck a load of penetrating lube (lulz) on there, leave it for 5 minutes to soak through a bit, then give it a whack. Never found a set of forks that a swift knock wouldn't get out, but they can be pretty stubborn at times. Quote Link to comment Share on other sites More sharing options...
bikeperson45 Posted January 24, 2011 Report Share Posted January 24, 2011 I had the same problem a few days ago. I just sprayed some WD40 around them, left them for a while and used metal hammer with wood a few times to get them out. Mine had been in for about 5 years I think so took a few good hits to get them out. Quote Link to comment Share on other sites More sharing options...

haydon_peter Posted January 24, 2011 Report Share Posted January 24, 2011 I'm sure you will need to remove the tapered split ring before removing the forks. I don't think I have ever had to use much force when removing a set of forks! If a hammer is required I would advice you place a bit of wood on the steerer to protect it then hit the wood rather than directly hitting the steerer!

court Posted January 24, 2011 Report Share Posted January 24, 2011 If you haven't managed to removed them yet, you can do it by hitting the face of the steerer tube that's sticking out, and not the top of it. This will shock the tapered split ring out of the top race...after all, hitting it down as you are should in theory only make it harder to remove due to the split ring doing it's job by tightening onto the steerer tube and holding it all together with the more force applied? I think it was a Pig that I was using when I had to do this. That should sort it. Quote Link to comment Share on other sites More sharing options...
