Trying to change timing belt on my 93 Maxima, trying to get the
crankshaft pulley off. Before I go wrenching on the center bolt, is
this a reverse-thread or normal bolt? If memory serves, and if I'm
thinking right, it's reverse. Am I correct?
Thanks for the help,
Steve

it turns CCW to loosen the bolt.

You may need a good quality puller to get the harmonic balancer off , a.k.a
crank pulley

.. to get the crankshaft pulley off. ..
Std bolt, open=ccw ...nice to loosen with a pneumatic too

Check the 'Favorite Links', top left: http://www.cardomain.com/ride/748507/

The FSM etc has confuzeus tightenin procedure. Whatever u do, in the end, verify that the belt bends downward half inch with 20lb force (as FSM says) between cam sprockets. (Free resting tensioner spring effects this tightness.

After "2years", its good to check/retighten the belt: pry cover top ajar, test this bend with long screwdriver or similar

..definitely need an impact wrench to get the bolt off. It won't work any other way
Having puller wont hurt. Like you, I have never needed a puller. Some pulleys have needed 'jacking' from opposite edges..

Starter off, locking the flywheel by its teeth, veeery loong tools - if no impact wrench
