I've come across situations like that and about the only thing I could think of was to pull spark plug #1, put a small rod or long screwdriver down the cylinder and turn the crankshaft pully SLOWLY AND BY HAND while I watched the rod move up or down. Once the rod got to the top and started to move back down I turned the pully backward and then carefully positioned the pully to the point where the rod was at it's highest point. I then did something to the mark on the pully so that I would know which was the indicator for #1, either a chalk mark or a little extra filing on the pully.

There is either a tensioner or an adjustment screw on a pulley. A Haynes manual or Chiltons manual will help with the routing of the belt, and how to adjust the belt tension as well. Usually the idler pulley is used, before loosening the top bolt , loosen the center bolt of the pulley.
Yes, it is used to adjust the tension on the A/C compressor. Looking into the engine compartment from the passenger side it is to the left of the alternator. To adjust tension you need to loosen the bolt which holds the pulley and then adjust the bolt which is directly above the pulley. Once you have proper tension tighten the pulley bolt.

1998 Nissan pathfinder crankshaft pulley bolt is right handed.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
Using a 14 mm wrench, loosen the bolt in the center of the tensioner pulley, then tighten the tensioner bolt with the same wrench. Then re-tighten the bolt in the center of the tensioner pulley when the belt is tightened to your liking.
on the camshaft pulley there are six notches located on the inside lip closest to the block. there is a 2in pin at the 1 o'clock position when viewed from the front. each notch is a certain degree I have yet to verify.
On mine there are a series of notches cut into the edge of the main pulley nearest to the engine block. The notches are not deep and can be filled by dirt and paint and so can be hard to see.
