Adjusting the LevelWind Position
As line is deployed in or out, the direction of the LevelWind travel and the direction the line as it is rolled
off the spool should be in-line with each other. The LevelWind’s reciprocating motion is generated entirely
mechanically via rotation of a diamond screw. The LevelWind Drive Belt links the diamond screw to the
spool. Spool rotation, in turn, drives the diamond screw. A pawl (dull blade) sits inside the diamond screw
grooves. As the diamond screw rotates, the pawl traces the contour of the groove and drags the follower
along with it. When the end of travel is reached, the diamond screw thread loops back on itself, which
causes the pawl to reverse direction and travel the opposite way.
To adjust the LevelWind position:
1. Follow
Lockout Procedure
to prevent winch operation while adjusting the LevelWind.
2. Disengage the LevelWind pawl by pulling down.
3. Move the LevelWind to match the position of the line as it comes of the spool.
4. Engage the LevelWind spring pin by releasing it. Ensure that the pin is fully seated into the dia-
mond screw groove.
5. Manually pull off line and observe that the when the LevelWind travels the line on the spool
matches the direction of travel and location so that line is pulled straight off the spool.
