mcnulty Posted February 13, 2009 Report Share Posted February 13, 2009 took 05 front fork apart according to ryp process but the seal and the centering bushings stayed in the lower part of the fork???they act like they are jambed in place. and yes the clip was removed. any sugestions as how to get thosebushings and seal out of the lower part as know the tefflon is junk. I think I found why the forks are sticky. help Quote Link to comment Share on other sites More sharing options...
trialsnutterman Posted February 13, 2009 Report Share Posted February 13, 2009 You'll probably be ably to get the seal out with a self tapping screw, screw one or two into the seal and pull the seal out with pliers. I'm not sure how strong the bushes are, I'm thinking if they are relatively thin and flimsy you might be able to use a long thin screw driver to hammer one edge over so collapsing the bush in on it's self but you risk damaging the fork. Hopefully someone will come up with a better method. Quote Link to comment Share on other sites More sharing options...
trialsnutterman Posted February 13, 2009 Report Share Posted February 13, 2009 Have you got access to a big Lathe, might be best to turn them out, once they get really thin they will collapse really easy. Do the top one first then the spacer between the bushes should come out no problems then do the lower one. Quote Link to comment Share on other sites More sharing options...
scraggydog64 Posted February 13, 2009 Report Share Posted February 13, 2009 I can't picture the arrangement on a Sherco but I think I had a similar problem on my road bike. The problem being the bush is stuck in the lower fork tube and you can't get behind it to drift or push it out. I tried levering with screw drivers etc. to no avial. What I did do was cut a bit of 10mm wide steel bar marginally bigger than the inside diameter of the fork tube and then rounded both ends so it was a snug fit inside the tube. I then drilled a hole so i could get a bolt through the middle (Part A), the bolt needs to be a relatively slack fit. I also drilled a hole in a longer piece of bar (Part to bridge the top of the fork tube. I put a bolt through part A and lowered it so it sat behing the fork bush so I had hold of the end of the bolt at the top of the fork tube. I then put Part B over the bolt so it bridged the top of the fork tube. Put a nut on and gave it a few turns and the bush came out no problem. I appreciate its had to explain. If your really stuck pm me and I will email you some photos or a pencil sketch. Regards Scragg Quote Link to comment Share on other sites More sharing options...
b40rt Posted February 13, 2009 Report Share Posted February 13, 2009 I take it that the bar sits horizontally under the bush, and the slack fit in the center is so it can more at an angle to get under the bush ? Quote Link to comment Share on other sites More sharing options...
scraggydog64 Posted February 13, 2009 Report Share Posted February 13, 2009 B40RT Dead right. I am not good at explaining these things though I could probably get a job for haynes manuals. Scraggydog Quote Link to comment Share on other sites More sharing options...
b40rt Posted February 13, 2009 Report Share Posted February 13, 2009 Always good to pick up techniques, and I particularly like home made ones. Know what you (refer to previous chapter, and do in revers) mean about Haynes manual's. Quote Link to comment Share on other sites More sharing options...
copemech Posted February 14, 2009 Report Share Posted February 14, 2009 As I recall, once you remove the seal, it should fall out. I think I follow that the bush on the end if the tube came off, so the tube came out of the slider without it, leaving it loose and the seal in place.

I think I follow that the bush on the end if the tube came off, so the tube came out of the slider without it, leaving it loose and the seal in place. Sounds like it to me too. My mentors taught me to use heat (not a "pencil" flame, but one that spreads out the flame and play it over the surface so as to not burn the coating) to "loosen" seals and then rap the fork tubes apart and it has worked every time, so far. You might try some quick heat on the outside of the lower leg and then jab the top of the leg against a piece of hard wood on the floor. The quick heat on the aluminum should expand it fast enough to release it from the steel bushing collar. Jon Quote Link to comment Share on other sites More sharing options...
bukor Posted February 14, 2009 Report Share Posted February 14, 2009 Same thing happened to me as I was installing new seals in my wife's bike last month. Everything came out fine, but the bushings were STUCK! Obviously this probably isn't the correct way to free the bushing, but it's what I eventually had to do to get them out. I just happened to have a 3' long, 1/4" diameter steel rod, placed the rod through the bottom of the fork and was able to very gently tap the bushings out.
