right remove the handle and turn the
stem 180% (you don't need to remove the
pin or cartridge to do this) Then put
the handle back on and you are done.

These instructions were right on the money, I know nothing about plumbing but I was able to change the cylinders in my tubs easily following these instructions. THANKS! Very helpful Website.

two pieces. Of course, I bought the wrong replacement
and had to make a second trip to Home Depot.
