    Front Axle Seized!

    Help and advice required.

    I wanted to replace my front mudguard and service my front brakes, easy peasy I hear you all say!

    I undid the two pinch screws and undid the front axle.  However, all that happened was that the fork legs splayed apart.  I used a rubber mallet to knock the Axle out to no avail so any ideas?

    I don't know exactly what it means that the fork bottles were separated, I think what happened is that the fork springs have fallen more than the others and now do not match to enter the central axis.

    That should not have happened, if more than one has fallen, it means that one has more pressure than the other.

    No matter how many blows he gives, he does not adjust them, because the spring pressure does not rise and the blows are not successful.

    What you can do is release one of the handlebar forks, it has a screw on the top and two on the bottom. (motorcycle tightly fastened) once you let it go up the fork effortlessly.

    Then attach the fender and you can fit the central shaft.

    Once this is done, you should lower the fork bottles to their place of origin.

    I forgot to tell you that the fork screws are important to adjust with a torque wrench to 25 Nm.

    In the case of a delicate part, if they are not tightened to 25 Nm, which is what the manufacturer has, it could break some of its screws.

    Did you totally remove those two fork leg pinch bolts or just undo them a bit?

    Sounds all a bit strange I must say,......what part could be corroded/catching I wonder? :187:

    I tried both ways, loosen and fully removed.

    Have you taken both calipers off?

    Sounds like you have but it's not clear...

    Earthman, I think what happened to you that when you take out the wheel and the fender, the forks by the compression of the springs themselves have been lowered and it may be that one of the forks has lowered one more than the other, and they must be misaligned and cannot enter the central axis ...

    When the wheel is removed, the forks are still aligned because the fender holds them. But ... if you take out the fender, the fork bottles rotate freely and one can lower more than the other.

    It would be nice if GarminDave sent us a picture of how they are now.

    Here’s my diagnosis :

    The Spindle is threaded at the opposite end to where you insert the 17mm Hex tool.

    The Spindle is obviously unscrewing from the threaded part of the left Fork
    but because it is not withdrawing it must be corroded and “stuck” onto one or both of the wheel bearing inner surfaces.

    The seized bearing(s) will rotate as the Spindle is unscrewed,
    but as the Spindle is fixed to the Bearing it cannot withdraw,
    and the result is that the Fork legs will be splayed apart
    by the amount that the Spindle is unscrewed.

    Time for some copious quantities of WD40 to be squirted into the Hub
    in the hope that it will free off the corrosion.

    I would not recommend you keep unscrewing the Spindle if it cannot be seen you be withdrawing as this is likely to bend the Fork tubes !
