Removing the coffin magnet: the plunger is threadlocked into the magnet core

Cause: The plunger shaft screws into a thread inside the magnet core under the large nut, and it is held with threadlocker.

Steps

• Pull the spring down out of the way.
• Hold the squared part of the shaft under the nut with small pliers or a wrench.
• Loosen the large nut with the right size wrench.
• Unscrew the shaft from the magnet core, breaking the threadlocker; use medium-strength threadlocker when refitting.
