Perrin crank pulley is this normal??? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I installed my perrin crank pulley about 2 weeks ago and followed all instruction meticulously. After install i cheked to see if there was a wobble and everything seemed fine!

Yesterday i deceided to do a little rechek on my pulley and noticed that the head of the bolt is offset from the bolt?? The pullley is perfectly straight no wobble or anything but the bolt in the center is not turning very symmetrically maybe 1 or 2 mm offset and is turning in kinda of an oval shape??
I doubt i could have warped the bolt with a 1.5 foot breaker bar so im just wondering if it is normal or if i should have the bolt replaced

Thanks mike,

Thanks mike,

Nope, they are all like that. It was not caused by anything you did. You must not have noticed that when you first installed it.

The hex and sometimes the outside of the bolt are not centered over the threads. It's just the way they make the bolt and it is nothing to worry about.
