12. Stand the screw on a soft surface with the threaded end down.
Use a small screw driver to push the o-ring (#15) down into the
recess of the nut.
13. Slide the spiral retaining ring down using a small screw
Driver. Spread the end that is nearest the nut apart and push the
leading edge into the groove on the inside diameter of the nut. Follow
the retaining ring around with the screw driver (in the same fashion as
threading a nut onto a bolt) until it snaps into the groove. Push the
snap ring out from the inside to make sure it is seated in the groove in
the nut.
14. Using the vise handle turn the screw counter clockwise while
holding the front nut until the nut comes to a stop near the holding
block. There should be a small gap between the front nut and holding
block.
15. Spin the holding block counter clockwise until the set screw is
facing straight up and in line with the top of the nut.
16. Place spiral retaining ring (#6) on the threaded end of the screw
and slide it down towards the front nut.
17. Take seal (#5) and using a utility knife cut a slit in the diameter
and place the seal around the diameter of the screw just behind
the threads at the end of the screw. This seal is very stiff. Cutting a
slit in it allows you to slip it around the screw without having to push
it on over the threads and possibly damaging the seal.
18. Place a small amount of grease in the rear nut (#4)
and thread it onto the screw in a clockwise direction
until the threads are fully engaged in the nut.
19. Stand the screw and nut up on the rear nut. Slide the seal (#5)
down and use a small screw driver to push the seal into the relief
of the rear nut until it sits below the snap ring groove in the nut.
