Any ideas on how to get the alternator pulley off? Is it LH thread or RH thread?

Cheers

Normal threading.

I like the shadetree mechanic way.

Impact gun is the easiest way by far. If you don't have one already, one of the small electric impact guns will fill the need for this and lots of other homeowner tasks. SeanR recommended them to me several years ago now, and that tool is by far the most-used power tool in my home workshop.

For U.S. readers, there's a holiday sale right now on the Makita tool I use for about $100 at Home Depot. I add a set of hex-to-square-drive from Harbor Freight for under $5, so I can use common impact sockets.

There are others available with significantly higher torque ratings, including some with the Milwaukee name on them. I like the light-weight Makita for other things too, and usually use one the air-drive impacts for the bigger stuff. And FWIW, there are very few 928 tasks that get any impact gun use here. Like removing large suspension bolts and the motor mount nuts.

I ruined the fan fins on one trying to get it off with just wrenches and vises and stuff...don't make the same mistake I did....pretty much need an impact wrench. I wound up taking it down to a service station and using theirs.

Ha.
I've shown up a few times at the local Indy for stuff like this, or a random crush ring or what-not.
They raised eyebrows the first time, but now I'm just that crazy Porsh guy.

I held the handle of my ratchet wrench in my open palm and smacked it with a rubber mallet a few times. Slightly painful, but it worked.

I use a strap wrench around the pulley to hold it and then you can use whatever you want to loosen the nut, an impact being the fastest and easiest.
