Engine was out of the car, so a Milwaukee 1/2" impact whacked the bolt right out effortlessly. In the car, it can be a hassle. I have used a chain wrench for leverage in a car before, but I am not thrilled with how it can gouge the pulley a little bit, though thats probably avoidable by wrapping it with something else first.

My issue is the bolt, not pulley sliding off Crankshaft. My engine is in, otherwise, we would not be having this discussion.

I would use chain wrench, if I was certain the pulley bolt was going to come off. Didn't want to risk damaging it.

Thanks to everyone for the help.

Since the last post, few things have changed for the better.

I now have a shop with a hoist! I have all my tools in close proximity and essentially every tool I need.

Had the car up, undershroud off, Transmission held with lock tool, used the breaker bar with 3 foot extension and wham, off it came.

The pulley wiggled off as with all Nissans in my experience.

So, trying to fit the new ATI, I still feel that it is somewhat tight. I measure and measured and it shows I have some clearance, but it seems tighter.

I will heat up ATI hub (with heat gun not torch), and try to cool crankshaft mount portion and see if that helps. I will also use anti-seize on crank shaft (per ATI instructions) tht may also help.

New crank end seal is on order.

Stay tuned.

I had mine clearanced a bit. Some don't do it, but MA Motorsports mentions the spec.
