    How do I adjust the cones on a Duraace 7700 rear hub?

    My 7700 hub is tight, and has ancient grease. I want to service it.

    I pulled the end off, but the cone itself is screwed down onto the axle and I can't get to it. It's buried in the freehub.

    with that comes the issue - I won't be able to hold it in place to tighten the assembly when I have the appropriate settings on the cone. How the heck do you get to it?

    Can't you get into it from the other side, where the cone and locknut should be easily accessible?

    Every Shimano freehub I've ever seen is adjusted from the left side, not the right.

    Here's an exploded diagram:

    Yes, unlock the left locknut and cone and remove them. And before you do anything else, put the driveside locknut back on and lock it to the cone again. Leave that side alone from there on. Personally, I'd suggest using an axle vise to immobilize the axle itself. Park Tool AV-1 will do the trick.

    I didn't realize the cone on the other side was attached to that nut. Dur dur.
    It's perfect now. Packed full of brand new grease and dog hair.

    Dog hair is not a good lubricant. Use only the finest cat hair: http://www.rideyourbike.com/shopcats.shtml
