Fits Statler and Gammill Machines with a 2 wire motor plug
This Z Motor Adapter (not pictured) allows you to install a new motor on your older machine. For many years the motors used a 2-wire connection, later models changed to add a third wire for grounding purposes. Coming out of the side of the old motor is a wire. 3-4 inches along (and before it disappears into the machine) there is a connection (you can kind of see a line along the black plastic covering). Pull firmly apart and the connection will separate, allowing you to see easily whether there are 2 or 3 metal pins. The new Z motor WILL HAVE 3 WIRES and so this Motor Adapter is required for those older machines where the old motor had just 2 wires so that your new motor can plug in.
