Abstract
A gear driven dial indicator is used to indicate the door closer size for a door closer having an adjustable closing force. A drive gear is attached to the door closer adjustment screw. In the preferred embodiment, this drive gear engages a ring gear which is formed as part of the dial indicator. As the door closer adjustment screw is turned to change the door closer size, the drive gear turns with the adjustment screw. The drive gear then turns the planetary gear which turns the dial indicator, thereby changing the indicated size of the door closer.
