    Default Fork Seal Removal

    My 2000 Funduro has only done 19K and has developd a leaking fork seal. I got the forks off but cannot budge the seals. We tried a fair amount of brute force by tugging and slamminmg the fork tube up to the seal , then tried heating and brute force. Still won't budge. It appears that the steel seal has seized to the alloy of the casing. Has anyone out there any advice on how to sort this.

    Thanks

    It might be a stpid question but you did undo the bolt that holds the slider to the top part?

    If it has been undone brute force should do the trick.

    Thanks Ton but sadly we did remove the bolt. I guess I'll try more brute force and if that fails will try a a hydraulic porta press.

    I had the same problem on some old Honda NTV forks, just had to clamp the slider in a vice and give it all!!!!

    got there in the end but was hard work

    nearly forgot to say that you could try some heat on the alloy slider, I would only try this if all other options fail!!

    I had the same problem - it took HUGE amounts of brutal violance to get the stanchion out. You may want to order new fork bushes because chances are you destroy them with all the hammering you'll need to do (I did).

    Thanks for all the advice. We got the forks sorted last week. I could not believe the amount of force needed to get the seals out. Still, all well now, new seals, bushes and gaiters so shouldn't have to repeat that for a while.
