I took the whole thing apart today and got my dizzy into better
alignment.
In the end even with no paper shims and the pedestal bolted down with
cleaned surfaces, the drive gear still has some vertical movement so I
don't think it needs any shims. I may add one just to give me something
to coat with gasket dressing to help seal that interface.
This is quite a busy little gear, driving the distributor and the oil
pump and the PI metering unit on the injected cars. I guess they are all
light loads in the end.

Stan---What might help cutting thru all of this proceedure is to surmize
what the good people at Triumph and Bentley wanted us to carry out. That
being, to have a slight amount of runnng clearance beween the bottom of
the pedestal and the drive gear. (Which would also give clearance
between the drive gear and the cam gear) The idea here is to keep these
two gears in proper mesh.
Too much clearance might permit timing variation. among other
undesirables. Too little, and parts would get hot, wear prematurely,
and/ or possibly lock up.
When you get this .005 clearance, you'll be able to stick a finger into
the center of the drive gear and feel a "wiggle" it as you lift it up.
If you can't feel any slack, it's probably too tight and needs another
shim.
Te "silicone" could have been the PO attempt to keep stuff from getting
in or out.
