CG 5 disassmble

I have read enough about the "sticky" grease to motivate me to relub my mount. But the disassemble has me stumpted. Do you have to have a special tool to take the worm gear assemble apart? Looks like it might require some kind of spanner wrench but the one I have is for retainers and is no where near strong enough.
