About to install a Sugino 75 bottom bracket (caged bearing/open setup) and have a few questions.

-What are torque specs for the bottom bracket cups? I have the crank bolt torque specs but not sure about the cups.

-Besides greasing the bearing cages/inner cups and light grease on the cup threads, do I need to do add any grease to the plastic shell? I was going to do the ends but not sure about the interior/exterior walls of the shell to help keep water out.

Thanks.
