    Shifter shaft seal..left side

    The seals weeping a tad and I have the new one. As it looks, I am thinking pry the old one out, wrap the shaft in tape so sliding the new one on doesnt cause damage, and seat the new one in the well.

    Sound about right???

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

    Pull the old seal with some wood/drywall screws.
    Probably not a bad idea to wrap some tape around the shifter splines but I don't remember doing that as it was so long ago the last time.
    I DO remember sanding the shaft where the seal rides with some mechanic's cloth and cleaning with brake cleaner/compressed air and applying some grease to the seal lip before installation and on the shaft where it rides.

      I was thinking steel wool actually then thought about just laying down some masking tape. I havent had occasion to change one yet but thought I was on the right track based on how it looked like it was set up. Gonna take the seal to Home Depot and find something to make a seal seating tool out of thats long enough to accommodate the shaft inside.

        You could wrap it with a piece of plastic from a milk jug if you wish to go that route. The large Cummin's engine front main crank seal comes with a plastic guide sleeve similar to that idea as well as some others that I have encountered.
        Remove after installation. Grease will do the same thing though.

          My issue is the rust and pitting and dont need the seal shredded almost instantly. I know you understand the situtation too.

            Popped a hole in the seal casing and used a zip screw. Took vice grips and gave a few yanks and it was out. Took longer to get the tools out than it took to extract it. Worked as you guys suggested.

              Watch out for the circlip groove in the shaft ragging the lip on the seal, use insulation tape to help it over. I used a garden mower plug socket, it was long enough to get the seal in. Don't let the shaft go in to far it will go out of mesh on shift mechanism, don't ask how I know !

                The shaft did move in a ways as I was sliding the seal on and I thought about that. Didnt think it had rotated any so I just pulled it out and put the retainer and clip back on. If it gives me any trouble shifting I will have to pull the clutch cover and realign..hopefully not though.
