1998 tracker 4 sp crank pulley wobble

[fixkick]

Thanks for your response. I didn't take into account the crank end play. So the measurement isn't useful. The reason I did measure it is because the crank timing gear is loose on the x/y/z plane (not torqued down) in comparison to the spare crank I have. I'm wondering if its possible that since it wasn't torqued down properly the crank snub has been ground down? For what its worth measurement was done without belts attached.

this is what kills dead many G16, vast failed. 
the new cog on a new crank snout is almost and interference fit,
in fact I used a puller  to remove,  3 engine  cogs here.
it is a snug fit out of the factory new,

the key there only is for getting the TDC timing right at first assembly, the key does nothing else.
only the proper torque holds it from walking on the snout,  damaged 5 ways, 
the key slot (an 2 key) the shaft surface 3 and the rear face gets torn up 4 and cog bore wrecked.5

see photos in my link of horrors.  House of horrors cog.
 why is easy fail is here:
#1 cause A/T transmission that , makes folks forget to lock the crank, so they can torque it. (5sp use 5th gear)
#2 not reading the TSB,
