I have a spare upgraded alternator layin around, I think it's a 180 amp or so, and It's bad, so I'm in the process of rebuilding it. I cannpt get the pulley nut to come loose so I tried putting it in a vice but it's very tight. I used pb blaster on the bolt also. ANyone got some ideas?

 

got it off..
now how do i proceed?

 

What's wrong with it? You would probably want to replace the brushes regardless of anything else. You could replace bearings, voltage regulator, diodes without testing, but that gets expensive.

Did you read this thread?

yup lol i did. it appears that all the components are connected together with rivets...so I'd need to drill them out.
This is an upgraded alt that I put in 2006, for a big class d amp, and it was $300 or something, and it went out on me a few months ago, so I'm trying to fix it.
BTW...do you think that an alternator off an infiniti G35 would fit the vq30?
