    fork tube removal

    howdy everyone,

    i'm trying to get the front fork tubes off to take for new seal. the wheel is off and all associated brake stuff. the pinch bolts are super tight or they used some crazy locktight goop. the top ones are not an issue. the ones on the lower tree are a real pain. i have removed the plastic tray that holds the horn for better access. i'm afraid of stripping out the allen head while trying to loosen them. one in particular. i can't get a ratchet with a hex key bit up in there. am i going to have to remove the front light assembly? has anyone else done this?

    also is there any sequence/trick for removing the electronics from the left tube?

    I’d try penetrating oil on the threads and also on the bolt heads. A little in the clamp gap wouldn’t hurt either. Those bolts shouldn’t be very tight (18.5 ft lbs); there’s a good chance you’re dealing with mild corrosion/seizing, and penetrating oil might help a lot.

    FWIW, WD 40 is better than nothing, but not nearly as good as a purpose made penetrating oil, like Liquid Wrench.

    cool espresso. i thought about that while walking my dog in defeat. it could very well be some corrosion. it has some miles through all types of weather. the pinch bolts for the front axle ere definitely corroded. thanks for the tip.

    I did it. Don't use ratchet - it is useless, there is not space for it.

    First high torque movement I did with this:

    then I made it with typical hex key.

    It is not fast, but works.


    As for disassembling the leg - you will need special head.

    Of course that was not my way, so I bought another tool for ratchet (check the pic below, the only difference - I found U-shape)

    thanks funtik. i've used the penetrating stuff and it's soaking now. i'm off to buy another tool. i'm having a suspension shop handle the guts of the matter. they do a lot of aprilias and others. i've used them before.

    That reminds me - it is a lot easier loosening fork caps while the forks are clamped than after you remove them; then you don’t have to worry about how to clamp your nice, smooth fork tubes in your rusty home shop vise. Ditto for the final tightening.
