Hey all, I found out last night my pulley was shaking pretty violently and so this morning I decided to take it off and found this. To be honest I thought the bolt came but I was wrong. I would definitely appreciate any help and advice! Thanks!
It's a COBB lightweight, that yellow is so obvious... :blol:there is an in between case too George, but will reserve mentioning it till he is able to hopefully get the rest of that keyway removed
that pulley doesn't look fine to me
what type of pulley was this?
yep, seen it a million times...pays to pay attention to it when you do the first timing belt service and periodically inspecting thereafterIf you have the stock harmonic balancer, the rubber can be separating.
If you need a replacement lmi, i have like 5 I'm willing to let go for cheap.
Hmm... That particular crank cam has less of the key covered. On the EJ's, about 3/4 of the woodruff is covered by the crank cam when installed, and when the pulley comes off it only covers more as the cam walks forward, so I'm thinking it tends to prevent keyway damage. The front of the key gets completely buggered, though. It's also something I really dislike about the key, since so little of it fits into the crank pulley it takes very little loosening to spin the key inside the pulley. That's what happened to me after I failed to torque the crank bolt to spec, the pulley loosened up just a teeny bit (assisted by the side loading of the supercharger belt) and even though it was an OEM steel pulley, it was shredded on the back.I was going to say, there is no way I'd be using that pulley for anything more than a paperweight at this point
Timing belt wise, yep, needs very careful inspection to make sure the sprocket didn't start chewing the inboard side of the belt
For the crank/key it all depends what he finds once he cleans the keyway out. I too used to think that the key being soft, it can't harm anything - till I had experience that proved otherwise (not a Subaru). When we g0t it all apart the slot in the crank was widened on the back end, and that made just fitting a new key impossible. Ended up needing a few new parts, plus it introduced me to the wonderful world of ATI's pullies. I'd never do a serious build of any kind without one anymore.
WOW, that looks like nothing freaking happened! The crank cam didn't even move! You got lucky, the crank cam must have been on it so long it didn't feel like walking forward. And the woodruff key barely looks touched. Guess that's an advantage of using the softer aluminum pulley. I would get a new pulley, don't reuse that one, and put it back together.All right I took the cover off and checked for play but I didn't take the belt off yet. The belt looks fine, I didn't see any rips or tears. Woodruff Key 1 Photo by Aaron2000Subaru | Photobucket
