    Fork Seal Removal

    78 GS750. The fork seals are in pretty good. Does someone have a good way of digging them out? Don't want to damage the sides of the forks.

    Thanks

    Take the slides out if you can't dig them out safely.
    I use a small chisel to cut one side then pry it out.

      Since the fork dust boot covers the top very well I take a propane torch and heat all the way around the seals till i can detect some little bubbling from the oil around the edges. This softens the rubber and breaks the old seals free from the tube walls. Then, you get a flat tip screw driver and JUST so it gets a grip on the inside rim of the seal and pry against the fork and it will pop right out. This has never failed for me. To seat the seals before driving them down and seating them, get them statred with finger pressure and level..invert and rest the seal on a flat board. Whack the cap bolts with a rubber mallet and this will seat them into the tube. Then use a piece of PVC or a big socket that just fits the ID of the tube to seat them into the fork all the way.

        Chiselling, cutting, or prying between the seal and the fork is a bad thing in that it will scar the sealing surfaces of the fork leg...in my experience and opinion, of course.

          If it's an air fork, just pump it up to about 80 psi.

            The sliders came out easily.



            I will try to heat this up today and get things loose. Burn baby burn.

              Dont need them till they smoke or anything...just get them hot enough to soften the rubber on the seals. Then go down the middle and JUST catch the inside rim of the seal with the screw driver and pry up..may have to go side to side but they will pop right out without any scarring of the seating surfaces in the fork tube itself. Clean the surfaces well with some laquer thinner or something and be sure theres no little pieces of old seal rubber left behind.

                This would be a time time to check your slider bushings. The ones under the fork seal and the ones at the bottom of your fork tube sliders.

                Ah, don't forget to take the retaining spring off the seals first!

                  deck screw.

                  go and grab a sharp wood screw, such as a deck screw, and drive it into the seal from above, keeping well clear of the fork walls. All it takes is one or two turns in. There should be a couple of metal rings bracing the sides of the seal, and they should help protect the fork walls.

                    I pry with a wood dowel instead of screw driver.
