Assembly Of Ball Nut Unit - Greenlee 1904Pg Instruction Manual

Assembly of Ball Nut Unit

1. Remove the return tube clamp and the return tube
from the ball nut.
2. Place the nut approximately midway on the spindle
(13) and align the ball grooves in the nut with those
on the screw.
3. Place a short length of rod or dowel into one return
tube hole to prevent loss of balls.
4. Place balls successively into the other return tube
hole, rotating the screw so that the balls are fed
along the thread and through the nut, until the ball
circuit is completely full.
5. Remove dowel or rod, being careful to not rotate the
nut. The balls must not be in the return tube holes—
balls must only be in the mesh between the ball nut
and screw.
6. On both ends of the return tube, place a small
amount of light grease.

7. Load this half tube half full of balls.
8. Place the second half of the return tube over the
balls and hold the two halves tightly together.
9. Place the return tube ends into the return tube holes
in the nut (the grease in the tube will prevent the
balls from dropping out).
10. Place the tube clamp over the tube (taking care to
keep the two halves together) and secure with the
clamp screws.
