Adjusting the Detent Force
If adjusting the Friction Cap does not provide enough tension, there is a spring plunger in the indexing hub that can also be adjusted to vary the force. Use a flat blade screw driver to move the plunger in and out as desired. A convenient way to adjust the plunger is to screw the plunger all the way in until it gently bottoms out. Then unscrew the plunger about one complete turn.
