Has anyone ever seen a harmonic balancer key way wear out before? and for replacement I was thinking about an aftermarket light weight pulley any opinions on that? Figured since it a boxer that there would be no need for a balancer and instead just a pulley... I seen a topic on dirty impreza about using a light weight pulley just was wondering on some more opinions on it

Plenty of people run the one piece pulleys. Just be sure to get the bolt good and tight or you'll have the same problem again.

Okay thanks, what's the best way of torquing it if it's an automatic?

A 12 in long screwdriver through the flywheel inspection port will hold the crankshaft. I put 130 ft lb on the bolt even though the 90's subaru spec was less then that.

the keyway isn't need - torque that mojo down and the pulley will not back off. it's iron crank so it's not aluminum and not prone to strip like much of the motor.
i've got a one piece on as well. no big deal, just bolt on and go. i noticed zero difference in performance with it.
