Soak it in lacquer thinner or acetone, but not a plastic tank, to remove all the old castor oil.
Lube it well with normal motor oil you put in your car.
You can't 'fix' pitting on the case. Just clean it up with thinner and an old tooth brush.
You can pull them all apart also if you wish to. Good luck. :)
