Please help with Kohler K304 shower valve

[smthompson]

I replaced a part in the valve and now I can't get the bell to screw properly back into place without the stem becoming very tight to turn. What am I doing wrong?

You need a more complete model number, but if you search on K-304- don't forget the dash at the end....that will just get you the shower valves. There are several different options, but if you browse through, you should see your model and how if goes together.
