For the mid-line bb's with the drive side cup built into the cartridge (Centaur and below), always seat the side with the cartridge first and fully and torque it to spec. Then install the nds cup and torque it to spec. If the bb shell is the correct width, both cups should be flush. If it's too narrow, let the nds cup stick out a little.
For the Record and Chorus bb's with two separate cups, install the drive side cup and torque it to spec. The slide the cartridge i andinstall the nds cup. Again, if the bb shell is correct, both cups will be flush.
