TR3A Thermostat Sending Unit

["Terry Smith" <terryrs@adelphia.net>]

In an effort to change the thermostat sending unit, I've removed the hollow
bolt from the housing (which I have dismantled and in the cellar), but the
sending unit bulb remained inside.  How does it come out?  Do I push it out
from the inside out, or push it down from the outside in?
