2084 slop

[Kneale Brownson]

The opening in my 2084 crankshaft tool for removing/installing the 
pulley bolt is at least 5.5mm larger than the projection in the pulley 
opening over which the tool fits.  Is this common?

If I have the pulley positioned against the tool to remove the bolt at 
TDC, the mark on the crankshaft pulley lines up with its dent in the 
valve cover perfectly, I can see my flywheel mark in the window and the 
distributor rotor points to its mark.  If I turn the engine against the 
tool to tighten the bolt, the crankshaft pulley becomes a tool off, the 
flywheel mark disappears and the rotor points a bit off its mark.

Is it my pulley, or is this normal?
