I discovered when checking for thigtness of the coupling of the worm
who the white gear in RA gearbox have a not linear movement at
64x-600x-1200x (e.g. like a 33rpm disk when play on a turnatable and
the disc is a bit twisted)
There will always be a small amount of up/down motion at the edge of the gear
disc. This is of no consequence and does not cause the sound that you are
experiencing. Once a year lubricate the gears inside and outside with a thin
white lithium grease.
