Default Engine Crank pulley

Ok all, I just discovered last night that my pulley was shaking all about and so I tightened the bolt and drove home. Well this morning I decided to pull the pulley off and this is what I found. Is there a way to replace it or not? Any help and suggestion would be great! Thanks!

Aaron

Here is a couple pictures I took.

You need to replace it. Looks like a Cobb Pulley.

I really like my cobb pulley. Probably going to get another one. Its like 1.4 lbs and the stock on is like 4 or 5 lbs. I did notice my car revs a lot quicker and maybe a very slight power gain but not much. I also got it because it was gold in color!

The crankshaft damage is the more concerning part, You're probably going to need to pull the plastic timing belt cover off and clean up the end of the crankshaft with a file (only if there is bent/damaged material in the way of the new pulley) before you can install a new pulley (yes you do need a new one). When you do install the new pulley apply loctite generously and hope that the rest of the key doesn't snap off, because that would mean a new crankshaft (aka new motor).

That pulley is f'd and so is your woodruff key. You need to get the key sorted first by a PROFESSIONAL. Then decide if you want the professional to install another lightweight or OEM pulley. One thing's for sure though, you need to reevaluate who works on your car as this job is literally one bolt and whoever did it, borked the install.....if it was you farm installs out from now on....if it was someone else, stop going to them.

I would suggest taking this to a professional. Like Unabomber said, you need a new pulley and woodruff key. If it did enough damage, I've seen it also mess up the crank where the key goes in. If this is the case you could need a new crank.

Ok, I got the cover off but I haven't taken the belt off yet. It looks like only the key is damaged. I checked for play but it didn't budge. Going to my local subaru dealership to see what I can get out of them and then going to the shop I use and seeing what they can do and then figure out my next move. Lol. Again I really do appreciate all the help.

Aaron

p.s. I'll definitely keep posting about my situation because I'm still a noob.
