The two dome rotation motors are 180 degrees apart; east and west side of the observatory. The west motor wheels began to loose their grip on the underside of the dome support ring (
DSR). When I first inspected the trouble, it appeared that there was insufficient tension from the motor chassis tension spring, at the left side of the motor chassis as shown in image below.
