Glad to read the OP's cage installation worked out. They are tricky. Doing a hammer installation, I inadvertently let my CZ-75BD sear cage disassemble itself today -- and now I know what CGW means when they say about the L-Spring, "Often lost, seldom found."
I found the L-Spring again and reassembly is almost complete. But using my SP-01 Tactical as a guide, I noticed that the L-Spring on that gun was not in the tiny notch it needs to be in to operate the lifter arm. I had used the slave pin to do a hammer installation on that pistol last week... but, shame on me, I must have let the pin go in just a tad too far, letting the parts loosen up too much, and allowing the lifter spring to jump out of the tiny groove in the lifter (but happily, the spring remained captive on the actual pin). I would never have noticed it, if I hadn't gone back this week to take a good look at the way the parts are assembled.
Something to check after using the sear cage slave pin.
