Default Flywheel & Compensator Shims for Primary Alignment

Hi guys, I have a question here as I'm working on updating our Harley parts application list. We have a 3-phase stator/regulator conversion kit for Harleys, but I've recently noticed some fitment problems with various models of bikes.

What I need to know to narrow this down is about the shims used on the crankshaft for primary chain alignment. Unfortunately, I'm not very familiar wit Harleys, and need to clarify some mechanical issues so I can ensure our stator fits correctly.

I'm attaching a picture to show what I believe is the correct layout under the primary cover:
Click the image to open in full size.

This is drawn looking down on the primary case internals from above.
The crank is in black at the top, with the stator in blue, mounted to the engine sidecase.
The rotor/flywheel is in pink, and covers the stator.
The shims are in green on the outside of the rotor.
The compensator sprocket (is this the right name?) is in black outside the shim, along with the locking nut.
The chain is dotted black lines.
The clutch is on the bottom.

I have a few key questions:

1)
How is the rotor held in place on the crankshaft?
Is the shaft tapered and has a woodruff key? Or is it splined?
The main thing I need to know here, is if the rotor slides onto the crankshaft to a certain point, and is fixed at that location...ie it is a fixed distance away from the stator windings.

2)
Where are the shims to align the primary chain located? From my understanding in my above drawing, the shims are located between the rotor and the countershaft sprocket, to allow you to adjust the alignment of the primary chain in line with the teeth on the clutch basket.

3)
Are these shims the only adjustment of the primary chain alignment?
From what I've read lurking through the forum it sounds like the transmission and therefore the teeth of the clutch sprocket can be adjusted too?

Thank you guys very much for giving me some information on these points!

Evan

Rotor is fixed postion as well as the stator. No shims. You need to get you hands on either used parts or the actual bike to confirm fit up and dimensions. Fastest way I know of. Both components are simple as dirt, once you see them but have the price of gold.

Hi Ron,
Thanks for the info.
I talked to a Harley Tech at a local dealership last Friday, and he confirmed this.
That was exactly what I needed to know!
I appreciate the help.
