Swamping out the crank pulley and the boss / spacer came out and didn't get aligned correctly on the reinstall.  Need help on the parts list.  We're ordering a new bolt, o-ring, and boss but we're not sure what else we will need up to the sprocket.  In the pictures you can see the back of the boss damaged at the keyed opening.  At the sprocket it looks like the key is the piece at about 10 o'clock and it's also damaged.  I think the sprocket is good, is that little piece the key #E50506? and is the shiny metal ring behind it against the sprocket a separate piece or part of the sprocket?

 

Anyone who has any additional information please help, thank you.

In general a Subaru only needs the crank pulley bolted on, that’s it. You don’t need Anything else. The key isn’t necessary at all unless you’re planning on installing the bolt too loose. 3 foot pipe over socket, crank down the bolt and the crank pulley will not come off.

I’ve repaired tons of these - mangled cranks, keys, pulleys from pulleys that weren’t installed right enough. Just clean up the metal shavings, make sure the sprocket isn’t damaged such that it’ll damage the timing belt, massage until pulley sits flush and bolt it on.

If you have an older gen with distributor, where you want to be able to set the timing off the crank then just stick any small bolt/wooden dowel, coat hangar, etc - through the dowel pin holes to line up the crank pulley.

Sure if you want the key and H6 cover and get it all perfect then have at it but they are not necessary.

Maybe my phone isn’t showing the whole thread but I don’t see any pictures or info. Don’t know what vehicle you’re working on or trying to do it what happened?

I have no idea what you mean by “boss” and other words you’re using. Crank pulleys don’t have orings although EZ H6s have a cover that maybe had an oring. It’s not necessary or requires. It yeah replace it if you want.

Trying pics again.  After looking at them on the computer vs phone I can see a crack in the sprocket now too.

ah a 2017 BRZ that certainly changes things. 

 

is it still under warranty?

 

i think you posted this in the wrong forum - this needs to go in the correct Newer Generation forum, maybe more people will see it?
