Default Crank pulley almost fell off

So I started hearing a weird noise a couple days ago, couldn't figure it out... Then I was driving and it dawned on me for some reason that it could be the crank pulley. So I checked it and sure enough the pulley was loose, kindof wobbling back and fourth, then wobbling up and down when I would rev the car.

Anyway i removed the pulley and never found the keyway / woodruff key. I thought it dropped in the timing cover when I removed the pulley, but I removed all the timing belt covers and I still can't find it.

Does this mean the shop that did the timing belt (before I purchased the car) put the crank pulley back on without the woodruff key, or could it have come out some other way????

Is it possible to just buy the woodruff key? Will it damage my crank if I drive without the woodruff key?

Any ideas?

Thanks

-Matt

an autoparts store should have an assorment of woodruff keys, esp one that has a machine shop. The wooddruff, key keeps the pulley from spining on the crank.

The result of no woodruff key is your issue.

This should be your part, it shows good on on subaru parts.com. Its what I come up with in my parts book.

looks to be the same one for all ej engines from 93 to 2001

If the pulley comes loose, and has been loose for long enough, it might have chewed the key up along with the Crank Pulley and Crank Sprocket. I've seen it happen several times. Inspect the crank sprocket very closely before you put the crank pulley back on. I've seen the keyway warn so bad that it allowed the crank sprocket to have about 10 degrees of movement on the crankshaft and it really throws the timing off and makes them run like crap. If the crank pulley is chewed up at all, I would recommend replacing it. (When the pulley comes loose, the key usually makes a big groove in the back of the pulley, and forces you to replace it). If you want pictures of damaged components, PM me and I'll be more than happy to give you examples of what happens when the pulley comes loose.

Default I just bought a woodruff key from the dealer for $4.60. In case anyone's interested

They wanted 141.70 for the crankshaft pulley for my EJ22. Is there a cheaper place to buy that part? Also is there a cheaper tool for removing the crankshaft pulley other than buying the Subaru special tool for 150+++???

I have a box full of those pullies. And junkyards are full of them. AS for removal? There are a handful of threads here about the breaker bar/starter method of removal...

Strange! I went to my local autowrecker and they said they had NONE for me. I have removed the pulley, now I need a way to hold down the pulley while I tighten it. Do you guys use threadlocker?

I'm going to try to build my own "special tool" this weekend. If I can avoid building my own tool, it would be better.

No threadlock and an impact wrench set to 100...

As far as junkyards, I guess it depends on where you live. Here in CO Subbys are the Accords and Civics of the state...

There are plenty Subarus here in OR but the autowreckers wanted to sell me the entire block.
