Ever take apart a Turbo actuator?

Generic pic.

The engine swap I'm doing, filled with coolant and there was a coolant leak from the actuator, turns out the threads in the actuator are stripped right out so I was going to buy a new actuator when i noticed it looks like the top housing can come apart? Cummins doesnt sell individual pieces but I wonder if any of you have taken one apart? I thought maybe I could grab a core and use the top section of the housing.....
