  • Such method includes the steps of moving the pin means axially relative to the connected shaft.
  • the method steps include securing a bolt to a threaded aperture formed through a pin until the bolt engages the motor shaft. Upon further rotation, the bolt will function to move the shaft axially away from the pin to disengage a spline connection thereof.
  • another bolt is threadably attached to the shaft and pulled to draw the shaft into the pin to reconnect the spline connection.
