Looks like that part of the gun is very similar to the Super Redhawk/GP100 design.
You can remove the cylinder from the crane without too much difficulty, but I would recommend not trying to remove the ejector star. It requires a special tool and attempting removal without the tool can bend the ejector rod (#3 in the diagram below) which is bad.
If you remove the cylinder from the crane, be very careful not to lose parts. There are some small parts and springs to deal with.

You'll need to depress part #28 in the diagram. It's in a hole in the crane. Push it down farther into its hole and you'll be able to remove part #30 in the diagram. Be careful not to lose part #29, the spring that tensions part #28
When you remove part #30, parts #22, 27, 32 & 31 will all come out of the front of the crane--. Be sure you know how they all go back together before taking things apart--referring to the diagram helps but you'll want to pay close attention to everything before you take it apart. Getting everything back together is a little fiddly. Helps to have an extra hand or two.
The video is pretty good, but parts #28 and #29 may come out when you do the disassembly and he doesn't show them coming out or going back in.
