Yes, the only wrong way to install the pulley is to forget the o-ring. I
have yet to see one bend without breaking. If it is visibly moving in/out,
then the crank is moving which means some ting happened to the thrust
plate and shims behind the flywheel. It should only be able to move ~
004".

Everything is pretty straight foward around that pulley.
Was that pulley "out of whack" when you got the van/engine? did you ever
notice? if something as just started lately, that big bolt is loose, if
not,
it as been like that for a wile and you never noticed!
There is no way that pulley will go bad if nothing happen.
If it as been like that for a wile, it was simply wrongly installed, it
was
force in and the key/groove were not align properly, to do so, you must be
drunk :-) There is nothing to it, align pulley, bolt it in. I never use a
torque wrench, i always use my impact gun for this one. As to belt, again,
there is nothing there. just leave some loose, i mean you should be able
to
move this one up and down about 1/2 in, or better, you should be able to
twist this one 180deg (even more) EASILY.
No, if that pulley is really offset, go see a mechanic before this one
spin
out an/or break the cranshaft!!! i have seen that happen, not pretty.
