Engine type EJ251AXBWL in a 2002 Outback, the AC belt jumped and was wound up behind the timing belt cover and the crank pulley. Part of the timing belt cover was melted by the crank pulley which was rubbing on the timing belt cover. I removed the crank pulley and the timing belt cover. The timing belt seems to be a good condition with only 40K miles since it was last replaced. The timing belt cover is slightly bubbled near where the crank pulley would be. The crank pulley itself has a couple places where there are tiny notches broken away. My first question is, has anyone seen this before? I am trying to figure out the cause of the AC belt failure. Looking at the Alternator Belt, this belt is well worn with cracking and a couple of missing pieces of splines. Now I am in the process of ordering replacement parts. Besides the Alternator and AC belts, and the timing belt cover, do you think I should replace the timing belt cover gaskets? I could take a file and smooth out the tiny notches in the crank pulley or should I replace it too? Thank you in advance for your comments!

Hi Everyone, Thanks first of all to everyone since I have read numerous threads to get as far as I am with my crankshaft pulley repair. The pulley had a significant wobble and the fan belt kept working its way off the PS pulley even though it was tight when I initially installed, reinstalled, now it just throws it off right away. So I have two questions now before I go further. 1. Woodruff key: It doesn't appear damaged, can I leave in place or if no how to remove? I have not taken out radiator or fan as of yet, trying to avoid. 2. It seems that the wobble has create a massive amount of metal shavings everywhere. It has also eaten through my cover and lots of shaving in there. I am able to do a timing belt repair but cannot do for a few weeks. Would I get away with installing the new pulley and replace cover when do timing belt? The cheapest crank pulley I can source is $170 new from Napa or $100 used from salvage. If I am redoing the timing belt I will put in the extra and buy new pulley, just hate to spend the money and wreck the new part. I am unsure why the wobble, should I be digging deeper or is this just a pulley fail? Appreciate any input or opinions ~ thanks! Rachel

Howdy folks, Newbie here. I need to inspect my timing belt---suspected jumped a tooth... see earlier posts by me in the last couple of days if you're interested in the full saga. I removed radiator, accessory belts already. Last step before removing timing belt cover is the crankshaft pulley, and I don't know how to get it off. I began following this tutorial by MercedesDieselGuy on youtube He advocates a bit of a redneck method for loosening the crankshaft pulley bolt (bracing a breaker bar against the body and cranking the motor for a split-second). I applied WD-40 beforehand and followed his advice; it loosened up with no problem. (It was only later that I came across this thread where user Alias20035 said (s)he doesn't like that technique, but as far as I can tell I didn't bork it). I can remove the crankshaft pulley bolt entirely, and the pulley itself stays in place. It rotates just fine (I'm using an old leather belt & vice-grips), but I can't for the life of me figure out how to get it to slide out. MercedesDieselGuy, in the youtube link above, recommends turning the pulley clockwise to align the hash mark with the "0" reading stamped on the timing belt cover. (Later in the vid he seems to change his mind; thinks that step may be unnecessary). In any case, I did that (using a white paint mark I found on the front face & grooves of the pulley) and it doesn't seem to help with yanking the pulley. The timing belt cover seems to be plastic---so there was nothing solid to brace against when I tried wiggling a prybar gently. Other notes: the grooves at the back of my pulley are banged up, a couple of chips, making me think previous owner &/or a sloppy mechanic had the same trouble I am having, and tried brute force. Finally, I used a small mirror and my headlamp to get a good look at the pulley's center hole. I can see a notch at the back of the pulley on one side; hard to tell if it's part of pulley or another component/bushing behind it. But if I slowly turn the pulley with my belt wrench while watching with the mirror, I can see the notch rotates with the pulley. Is that back notch the "crank key" referred to in the thread I linked above? Any advice on how to get this dang thing off? Is there a trick to it? Thank you!
