Z, thanks for posting these pictures.
I'm going through this in my head trying to visualize the assembly of this amazing bit of pieces. Please correct me if I'm wrong.
Okay, I think the rotor will bolt to the under side of the Centa housing with the spline holding the drive side of it on the S&S crank.
So the larger Centa outer hub is bolted to the motor crank and has some possibility to be out of round, off centerline axis and "may" cause some vibration. It looks like you have a new bolt and washer for this purpose.
I see a bolt pattern in the top of the out Centa housing, but cannot see anything in the pictures to bolt there. Maybe if nothing goes there, Centa used this portion of their aluminum mold for another purpose.
The new shaft would go in from the trans side of the adaptor plate between the compensator housing the bell housing of the trans, of course a new bearing with the new parts. The retainer holds in the new bearing.
The Centa inner webbed part will slide onto the long end of the new shaft and probably be retained by the nut and washer.
Of course the rubber logs will be slid into the inner and outer during assembly. But with the amount of pre-load on the rubber logs, it looks like it could be hard to hold and slide all four rubber logs in at the same time.
What I don't see is any means to "couple" the two halves together for alignment purposes. If there is any miss alignment between the comp housing, trans adapter and bell housing, the unit will not be on the same center axis and could cause vibration.
I know it would be very hard to assembly, but maybe if there were like a trans input shaft pilot bearing in the Centa outer housing just above the crank bolt area. This would allow the inner hub and shaft to pilot from the opposite direction.
I would think that's why some have the new vibration and some don't. It will all depend on the alignment on reassembly.
On your current assembly, there is still the BMW type 6-bolt rubber spider that will allow and compensate for "some" out of alignment. I just see no true way to confirm true alignment of the Centa system. Please enlighten me.
Just for grins and giggles Z, how many dollars are laying on the top of your table?
I look forward to your review and pictures of the installation process.
Have a great holiday weekend.
