I finally found a UK youtube clip that show it, but his spring is obviously larger or tensioned ligther.
In the real world, at least on a Eagnas, that spring is a LOT tighter. I finally got the spring onto the drum last night by winding it one quarter-round at a time and holding it onto the drum with my fingernails. It finally disfigured the springs a little (stretched them open), and at least it works again. Thanks guys.
