Large Black Output Gear ( 1000095 ) used in 460i and 460TC Only.
Does Not work in older 460 NovRam, nor any 440 series timers.
This gear has no "gap" or overhanging "teeth", like the output gear used in the 440 series of timers ( Gear - Red or Black Output 440 Timer - 420B52, 1001583 )
So, don't be confused by their similar appearance / color.
