In older versions of Ansys, you would have to go into the CAD system and put the pin on the left side of one hole and the right side of the other hole to get the clearance taken up in the correct direction before starting the solution.  Newer versions of Ansys include a Stabilization Damping Factor in the Contact definition that allows a pin with clearance to the hole to sit in the center of the hole, not touching any side, and the stabilization will allow the solver to close the gap during the solution, which is an amazing time saver over the older version.
