Only the cartridge assembly is placed in the balancing machine. That is the bearing housing with the backplate in place and the turbine wheel and shaft, and compressor wheel.
The compressor cover and turbine housing don't need to be attached to spin it up with air pressure and grind metal off the turbine wheel "nut" to balance the assembly.

After balancing is done the compressor cover and turbine housing is installed and it's done.

Watch the video... Turbo Technics VSR balancing machines - YouTube

edit: this video may be better, i don't get sound on the other one.
