The harmonic balancer (pulley) spun loose from the nose of the crank! They no longer use a key and keyway design for the pulley, and I need to know the proper procedure for replacing the pulley!

Hello,

On this vehicle you need to mark and note the position of the harmonic balancer before removal.
Did the complete pulley come off or did the hub stay on the shaft?
Unfortunately, the manual does not provide the scenario for the replacement when the pulley is off without any markings.

I have attached diagrams below for your reference.

Let me know of any questions.
Thank you.

Hi Sean, thank you for this information, but I was also hoping to find out the torque sequence or procedure!
