Yea, so apperantly whoever installed the GFB crank pulley on my car either didn't properly tighten it or messed something else up, because today at about 7:20am, the damn thing fell off. Yea, Fell...

It made no noise so i figured a belt broke or something because the battery light came on (no alternator) and the steering was hard as a rock (no power steering.) Eventually the car died, about 1.5 miles away from the shop and uphill none the less. So I walked to the shop, grabbed the 22mm I needed, threw the pully back on (the damn key was missing by now, but i only had to get it to the shop) went to start it ,and no compression. boost gague shows pressure in the mani when cranking. $10 says I found where the key went....timing cover.... haven't had the cover off because I had to go to work... damn pulley

This seems to have been brought up a lot lately. Few people having trouble with pulley wobble. In another post someone said the torque spec should be much higher than what the FSM suggests.

Ya it says like 70ft-lbs in a haynes manual, but subaru told me 140ft-lbs, and mine fell off, 300 later, i got a new key, and a new pulley, and belts, and i could only torque the bolt to 100ft-lbs, so i brought it to subaru, they used a wrench with 4 bolts at the end to hold the pulley, and torqued it to 140ft-lbs and i watched them.

Techs at work torque them to 150 ft/lbs, you can hold the crank still useing a screw driver inserted in an access hole to the flywheel/torque converter behind the right hand cylinder head.

yea, when I put mine back on i used something similar to locktite as a bit of reassurance. and before anyone goes "OH NO DON'T USE LOCKTITE!!!" i only used a little bit and torqued it properly.

Using the medium strength locktite is fine, and in fact I recommend it, and was told so by a very reputable subie engine rebuilder.
