Is there any way to get the nut holding the alternator pulley off without using air tools?

I have the pulley secure and I am putting over 250lbs of torque on this nut and it is not budging... how can I get this nut loose?

I need to pull off the old pulley because I am upgrading it with a pulley kit.

 

I managed to get mine off using a long *** breaker bar (3' long). How can you even put that much torque on it without air tools?

 

Took it by midas and the guy got it off in 3 seconds with air tools, lol

 

It has loctite on it - you need an impact with the correct socket. Several rattles of that and PRESTO - it's off


Later

 

it took me 2 alternators to figure out you need an Impact tool!!!!

 

Just take it to a shop up the road that isnt busy. Most will do it for free.
