As above the ratchet is screwed onto the ejector rod shaft.
I don't recommend it, but some people use a socket that fits over the actual ratchets as a wrench.
I used a special tool that fit over the ratchets, but this was really nothing more than a flat bar with a octagonal hole that was a snug fit.
Note that the ejector rod and ejector are staked in place. This often distorts the threads right on the end.
When you screw the assembly back together, things may not go on straight because of the distortion.
For that reason, I used a die to chase the ejector rod threads to insure it went on correctly.
Once you get it on wrong, you're in big trouble because the ejector will be at an angle and you can't get it straight unless you have the threading die.
Also note, the head space is set on these guns by precision machining the rear face of the ejector to set the space.
A used ejector will have already been set for a different frame and may be too short to be usable.
Check head space.
If you need to further disassemble the ejector rod and spring, this requires a special tube wrench. You cannot get it apart any other way.
Brownell's sell the wrench.
