[Healeys] overdrive planetary alignment

[Richard Ewald]

bwaaaah?
This makes slightly less than no sense to my 15 watt brain.
If you have the planets out of alignment it will throw the sun gear off
center?
WTF?
Assuming that the planets are concentric it should make no difference the
position of the planets when the sun gear is fitted.
If the planets are not concentric the sun gear is going to wobble as planets
walk around the sun gear, and the mesh between the planets and the ring gear
will vary and quite possibly bind.
Like I said WTF?
Can somebody explain this to me using short simple sentences?
