Step 1: Remove the three small set screws from the center of the Clamp (use the provided 2.5mm hex key).

Step 2: From the bottom surface of the clamp, thread the Brass Bushing into central hole of the C-12.  A penny or similar sized coin can be used as an installation tool.  NOTE: Make sure the bushing is fully installed and is not protruding.  The purpose of the bushing is to keep the bubble level from falling out of the stem.

.

Step 3: Attach the C-12 to the ball stem using the three M3 screws and tighten with the 2.5mm hex key.  Lightly tighten all three, then go back and firmly tighten each one.

There should be a piece of foam in the stem’s central  hole; do not remove it!  Its purpose is to keep the stem’s bubble level from rattling around.
