Re: Reloading Ballscrew?

First step, check the balls to see if they are all one size or do they
alternate full size/under size. If they alternate, separate the balls into
two piles.
Do the recirculating tubes come off? Some are attached with screws and some
are pressed into their holes in the nut.
You will need a dowel the size of the minor diameter of the screw and a
sleeve over the dowel that will hold the dowel centered in the nut to get
you started.
Start feeding the balls (big one, little one, big one) into the
recirculating tube hole while turning the dowel just enough to move the
balls into the nut. Keep sliding the sleeve out of the way as the balls take
up the space. When the nut is full, put the rest of the balls in the
recirculating tubes (you might need to use a little grease to keep the balls
in the tube) once it is all together, screw the ball screw in letting it
push the dowel out.
