SUBTASK 27-51-32-480-001
(1) Install the lever and clamp tool on the ballscrew:
NOTE: The lever and clamp tool is a part of the tester, SPL-1753.
(a) Put the lever and clamp tool in its position on the ballscrew aft of the ballscrew nut.
NOTE: Make sure the load surfaces of the lever and clamp tool touch the aft side of the
ballscrew nut.
(b) Tighten the clamp-up bolt to 200-300 pound-inches (22.6 to 33.8 newton-meters).
NOTE: Make sure the handles of the lever and clamp tool are in the relaxed position.
SUBTASK 27-51-32-480-002
(2) Install the dial indicator assembly on the ballscrew:
NOTE: The dial indicator assembly is a part of the tester, SPL-1753.
(a) Put the dial indicator assembly on the ballscrew.
NOTE: Make sure the pointer touches the forward end of the ballscrew nut.
(b) Put the strap around the ballscrew to help hold the dial indicator assembly on the

(c) Adjust the dial indicator to zero.
SUBTASK 27-51-32-220-001
(3) Measure the backlash of the ballscrew and ballscrew nut:
(a) Move the handles of the lever and clamp tool together until the dial indicator stops.
NOTE: This will apply a load to the ballscrew nut, and move it forward on the ballscrew.
(b) Use the dial indicator to measure the movement of the ballscrew nut.
NOTE: The movement of the ballscrew nut is the backlash.
(c) Do these steps a total of five times to make sure the movement of the dial indicator is
repeatable.
