This is not good.

What happens when the cylinder is put back into the hole and it is not properly lined up it shears the end of an indexing pin off. The fix is to remove the IP side cover and see if there is enough pin to push it further in. I did the same thing on one port on the same application IP and had the IP shop fix it. Hopefully there is enough pin left to push it in where it will index the way it is supposed to.
