front pulley bolt, how tight is that damn thing?
 

I tried to pull off my pulley tonight. Started with a ratchet, progressed to a 1/2" breaker bar until I thought I was going to break my engine stand, then a 1/2" impact gun, thing didn't budge. it isn't left hand threaded, is it?
my impact gun is old and weak but it should still hit at least 200 ft lbs.

Mine was very tight and we had a heck of a time breaking it loose on my 930.

Not sure what it was torqued to before, but it was ungodly tight when we tried to break it loose.

I live in Orange also and you are more than welcome to try my Snap-On impact wrench. I have had good luck with it.

You likely have a "Durlok" pulley screw: 125 ft-lbs installation torque, even more to loosen. See:

Oh well, shame on me. My IR 2131P impact gun broke earlier this year and I've been putting off getting it fixed. My excuse was that I can use my old worn out "made in china" impact gun for most things.
Obviously it doesn't hit hard enough for this job. Looks like I have an excuse to spent the $ on parts to fix the IR gun now.
Anyone have a lead on where to get OEM IR pneumatic parts for reasonable costs? I know I'm dreaming but I had to ask.
I have a place I deal with at work but they aint cheap.

EDIT: i just found a place online that sells a complete repair kit with hammer anvil for $55, I ordered it so everything is good again. That price is alot better than the $125 I was originally quoted to repair the gun ($100 parts, $25 labor).
It's supposed to hit with 600# so if it doesn't get the bolt off nothing will.
