Help removing alternator pulley for Whipple SC 10 rib

[aedfam]

Update: I got the pulley removed. I used a H17 socket like @Jmeo mentioned in a previous post. He was also helpful in private messages. The problem was with the torque gun I was using. I could not get it to move with a Milwaukee medium/compact size torque gun. But thanks to @db252 for mentioning to try using a different torque gun which is what I did - I put the H17 socket on a larger gun and it came out within seconds. For anyone attempting this in the future you will need to hold the pulley tight. Also I don't know if this helped or not but I also sprayed some WD40 on it and when removing it I tapped the gun forward one quick time then put it in reverse to pull that sucker out.

Generally you need an impact gun for the alternator nut. I would start there.

I have an impact gun, I still need to know what socket to use to remove that nut with the impact.

Maybe try some by hand till one fits without slop? Probably a 15mm would be my guess

The stock pulley is removed using the H17 like you’re using. A really good impact is your best friend as not all impacts are alike. Of the 10 rib installs I’ve done, using the impact while holding tension with the 6 rib belt around the pulley has always worked. The new 10 rib pulley will be held on with a nut.

Takeoff the alternator and take it to any shop. give them 20 bucks and they’ll do it for you

Nice, glad you figured out the issue. My old brain was right after all, the impact was the issue, not the noodle.

I couldn't remember how many ugga guggas I gave it, but I knew it came off without issue.
