Just over 6".  You'll want at least 6.25" for clearance.  From memory, 
ID is just over 1.5" I believe.  It's a fairly tight fit on the sun gear 
shaft.  I believe the shear bolts are a 4" spacing.

It's all put together, so that number is rather difficult to come by 
right now.  I believe it is right at 3".  I'm thinking the bolt circle 
was 3.375" diameter, but I'm going to have to reserve the right to be wrong.

1.75"


I fabricated a fiberglass shield that sits between the stator and PSRU.  
The object being to keep trash out of the rotor.
