    shock mount stuck on 160 HD

    hey everyone:

    having an unusual problem

    I've got an RC4 on my HD, and id like to change the spring on it.

    so i go out to the garage, unbolt the front shock mount (the one in the limbo chips), comes out no problem.

    i start to unscrew the back shock mount, and something seems very, VERY wrong: the axle itself seems stuck on the press-fit mounts. as i unscrew the axle, the press fit closest to the head of the axle moves as i unscrew the axle. the net result is: instead of the axle coming out of the frame, its just WIDENING the gap between the rear triangle.

    so, i do the next thing i can think of: take a soft hammer, tap the the press fit back into the shock - again, no problem. the issue remains, though - the axle doesn't want to come out of the frame.

    I'm totally at a loss.

    I had a problem like this on my old Mojo C. I had bent the rear shock mount bolt, Since getting a Ti bolt kit I never had the problem again and now I have a HD no prob either. On the C I had to drill the threaded end of the bolt out, without damaging the threads in the frame. This is a pretty delicate operation starting with a smaller drill and going up to the just below threading size.

    I would try using lots of spray lube before drilling out the bolt.

    I Just want to clarify a few things.
    Can you get the bolt unscrewed from the frame?
    If you can, try using a small metal rod to tap the bolt out with a hammer. If you don't have a metal rod the right size you can use an old blunt drill bit, a smaller bolt, or a small screwdriver that you don't mind getting burred.

    Spray some WD40 or penetrating oil in there.
    You could also try getting something to keep the triangle from widening. Maybe a belt or tie down strap. Then as you unscrew there is no way the gap can widen and whatever bond exists between the bolt and mounting hardware will be broken.
