Hmmm, I thought I posted a reply last night but now I don't see it!
Let's see. Here is a link to some pictures - never mind... it won't let me post a link

It says I have to post 5 or more times until it will let me. If you want to contact me at my email maybe I can send you the link via email. Mine is

The big round black piece is the cylinder that won't spin. There is a rod going into it (that the stick/shaft goes into) and it simply does not "spin". If the whole cylinder is supposed to spin once it is installed it seems way too tight in the opening when assembled to be able to spin.
So once I turn the motor on it simply snaps the stick/shaft.
Any advice you can give is appreciated. As I said, I am determined to do everything I can before I drop $400 - $500 on a whole new lifter pump!!!
Thanks!
