That may be OK, but realize that you MUST use a new crank bolt. The crank bolts are one time only use for torque and torsion reasons...they are compromised upon removal.

Also, if you are looking for changing the crank pulley out why wouldn't you go with the 185mm. It does not limit what other modifications you can do, you can still belt wrap, HE, Intake, pump, IC separation, etc...

Nothing changes except it provides more power...it is a proven part for the AMG 3.2L engine.
