[SEL] Fairbanks Morse ZD Flywheel Magneto Timing Mark Question

[FRM8198 at aol.com]

Hi List,
Here I go again.  
I have two Fairbanks Morse ZD flywheel crankshaft assemblies which are 
pressed together.  The problem I am having is that the flywheel magneto timing mark 
on the rim are NOT in same relative position on both assemblies.  Using the 
reference tooth (beveled) on the crankshaft (camshaft mating gear) timing gear, 
one assembly has its timing mark is about 90 degrees clockwise (opposite the 
rod journal) facing the rear of the flywheel.  On the other assembly, the same 
relative flywheel timing mark is about 195 degree.  Which one is correct?  One 
of these assemblies must have been pressed together incorrectly.  I don't 
think that the flywheel could have rotated on the crankshaft.  Is there any other 
procedure (other than using the flywheel timing mark) available to time the 
magneto?
On the bright side, the good thing about finding these discrepancies, it 
tends to make the gray matter work in an overtime mode.
