Sun May 28 20:54:20 GMT 2000 PICS End Patrol **PICS PROBLEM**: Sun May 28 22:10:43 GMT 2000 I disassembled the occulting wheel gearbox and cleaned and inspected all the parts, there was no damages, maybe the noise was gear chatter caused by vibration harmonics. I repacked all with grease and it sounds good now. Before disassembling I isolated the noise to the motor/gearbox assembly using a power supply. WEATHER COMMENT: Sun May 28 22:13:55 GMT 2000 Lots of clouds for the last few hours.
