[GreenKeys] Model 19 gears

No matter which oil or penetrant you prefer, heating the stuck bearing 
will greatly help freeing it up.  Heat softens the varnish created when 
oil gets rancid and helps the chosen solvent dissolve it. Good judgement 
in the source of heat and ultimate temperature is crucial. My favorite 
method where there are no plastic or other easily meltable parts is to 
use  drops of oil as a heat bridge between the tip of a large soldering 
gun and the shaft or bearing to be freed, triggering the heat on and off 
to keep the oil sizzling but not smoking.
