Position the side block collar 13.5 mm from bottom of
center hub to top of side block collar. Slightly tighten(should be able to still move it). Move the side block pins up in the side block
collar. May have to rotate side block collar one way or the other to
align the side block pins with side block collar. Remeasure and then finish tightening.
